1.1.2 Display During Power-Up

Display flashes the parameter set number between 300 and 399 for about 2 seconds.

1.1.3 Display With No Run Command

The three center segments are illuminated continuously.

1.1.4 Displaying Target and Actual Frequencies If the commanded frequency is changed while the drive is stopped the set frequency will display and the Left Status LED will illuminate. After about five seconds, the display will begin alternating between the set frequency and the stop indication shown in 1.1.3 above. Press the Mode button to stop the alternation, if desired.

Set frequency (10.2 Hz shown). Left Status LED illuminated.

When the drive is started, the display will show actual frequency as the drive ramps up to the target frequency. The Left Status LED will flash to indicate that the drive is accelerating or decelerating. If the target frequency is changed during drive operation, the display will indicate the target frequency until the actual and target frequencies agree. At this time, the Left Status LED will illuminate steady for about five seconds and then extinguish. This indicates that the target frequency has been reached and the display is indicating actual frequency.

1.1.5 Changing the Frequency Command Source

The source of the frequency command can be changed while the drive is running. For example, a digital input may be programmed to change from the 0-10 VDC input to 4-20 mA input. If this is done, the display will momentarily show a message to indicate the new speed source. Refer to Table 1.1 for a description of these messages. If the drive is being controlled by any other source besides the ∆ ∇ buttons, a press of the ∆ or ∇ buttons will cause the display to momentarily display the frequency source. Example 1: Assume the drive is running and the present frequency reference is the keypad and TB13A is programmed to select a 4-20 mA signal as the speed source. When TB13A is connected to TB2, the display will flash “EI” to indicate that the frequency reference was changed to the 4-20 mA signal. If TB13A is opened, the display will flash “CP” to indicate the reference was changed back to the keypad. Example 2: Assume that the frequency reference is a 0-10 VDC signal. If the ∆ or ∇ button is pressed, the display will flash “EU” to indicate that the reference is the 0-10 VDC input and that the ∆ or ∇ button cannot be used to change the frequency.

1.1.6 Display Messages

2.0 Safety

Safety is an important concern when working with any electrical equipment. AC drives operate at dangerous voltage levels and dangerous voltages can be present for several minutes after power is removed. Only persons experienced with the installation, operation and maintenance of AC drives should be allowed access to the drive enclosure. Failure to follow proper electrical safety procedures could lead to serious injury or loss of life.

2.1 Danger

This manual will use the following symbol when, due to the nature of the procedure, serious injury or possible loss of life is an issue.

The symbol will be accompanied by a boxed description in bold text describing the potential safety issue and steps to take to avoid injury. An example is shown below.

!DANGER

HAZARD OF ELECTRICAL SHOCK OR BURN!POTENTIALLY LETHAL VOLTAGES EXIST IN THIS DRIVE AND MAY REMAIN AT A DANGEROUS LEVEL FOR SEVERAL MINUTES AFTER POWER IS REMOVED. BEFORE ATTEMPTING TO SERVICE THIS CONTROLLER, WAIT 3 MINUTES AND MEASURE THE DC BUS VOLTAGE TO INSURE THAT IT IS ZERO.

The DC bus voltage can be measured by placing a DC voltmeter suitable for 500 VDC (230V drives) or 1000 VDC (460V or 590V drives) across the B+ and B- terminals. Only an experienced electrician should attempt this measurement.

!DANGER

2.2 Caution

In addition to the Danger symbol and typical statement shown above, some actions have a smaller potential for injury but failure to follow proper procedures could cause damage to the drive or to the driven equipment. This manual will use the following symbol when the operation requires care in performing the procedure but conditions are not normally life threatening.

The symbol will be accompanied by a description in bold text describing the potential safety issue. An example is shown below. Notice that Caution alerts are not boxed.

!CAUTION

CONSULT THE MANUFACTURER OF THE MOTOR AND THE DRIVEN MACHINE BEFORE OPERATING THE MOTOR ABOVE RATED SPEED. FAILURE TO DO SO MAY RESULT IN DAMAGE TO EQUIPMENT AND/OR PERSONAL INJURY.

2.3 General Safety Precautions

2.3.1 Always • Read and understand the contents of this manual before attempting to

install or service the AC drive. • Allow only qualified persons experienced with the installation, set-up

and maintenance of power electronic devices to work on this equipment.

• Disconnect power before attempting to work on the drive or connected motor.

• Follow plant and electrical code lockout procedures to insure that power is not accidentally applied while working on the drive, motor or driven machinery.

!CAUTION


7

• Measure DC bus voltage with a meter capable of handling DC voltage

up to 1000 V to insure that the DC bus capacitors have fully discharged before touching any components or terminals in the drive enclosure or before opening the motor conduit box.

• Insure that proper grounding procedures have been followed during installation of the AC drive and motor.

• Follow proper procedures for handling static electricity sensitive electronic equipment.

• Insure that the AC line voltage at the drive installation agrees with the drive rated voltage, as imprinted on the ratings label on the side of the drive or as listed in the Specifications, Section 8 in this manual.

2.3.2 Avoid • Working on the drive when power is applied unless absolutely

necessary for troubleshooting purposes and then only by a qualified electrician.

• Touching the drive heatsink because of the possibility of burns due to elevated temperature.

2.3.3 Never • Remove or install the drive cover while voltage is applied. • Never stand directly in front of the drive when applying power. • Never connect or disconnect any wiring, either power or control, while

power is applied to the drive. • Never touch any component on an electronic circuit board with power

applied. Some components are at DC bus potential. • Never short the DC Bus (B+) and (B-) terminals to discharge the DC

bus capacitors. • Never run conductors from multiple drives and motors in the same

conduit or raceway.

!DANGER

HAZARD OF ELECTRICAL SHOCK OR BURN!NEVER ROUTE CONDUCTORS BETWEEN MULTIPLE MOTOR AND DRIVE COMBINATIONS IN THE SAME CONDUIT OR RACEWAY. OPERATION OF ONE DRIVE MAY RESULT IN VOLTAGE BEING INDUCED INTO A SET OF MOTOR LEADS EVEN THOUGH THE DRIVE SUPPLYING THAT MOTOR IS OFF AND DISCONNECTED FROM ITS POWER SOURCE.

!CAUTION

ROUTING MULTI-MOTOR, MULTI-DRIVE CONDUCTORS IN THE SAME CONDUIT OR RACEWAY CAN RESULT IN DAMAGING VOLTAGE TRANSIENTS THAT CAN CAUSE PREMATURE MOTOR AND/OR DRIVE FAILURE.

3.0 Inspection and Storage

3.1 Inspection

Always inspect MD200 AC drives upon receipt to insure that no shipping damage has occurred. If damage is suspected, contact the freight carrier immediately to file a damage claim. Also, contact your local Sumitomo Machinery Corp. of America (SMA) Representative or Distributor to receive a Return Material Authorization and return the drive for inspection and, if necessary, replacement or repair. Attempting to install or operate a drive that has been damaged may create a safety hazard.

The following signs may indicate possible shipping damage that should be investigated further:

• Visible damage to the drive shipping container including cuts, tears or

punctures. • Signs that the container may have been dropped such as deformed

corners. • Signs that heavy items may have been stacked on top of the drive

container such as caved-in top, bottom or side. • Opened containers. • Loose parts inside the shipping container. • Evidence of water damage.

3.2 Storage

If the AC drive is not to be installed immediately, it should be returned to its original shipping container and stored in a location that meets the following conditions.

• Temperature maintained within -20°C to +70°C (-4°F to 158°F). • Not prone to large temperature swings. • Humidity within a range which will not result in condensation. • Away from dripping or splashing liquids. • Atmosphere is free from corrosive gasses and/or conductive dust. • Free from excessive vibration.

4.0 Installation

4.1 General Precautions

MD200 SERIES DRIVES ARE SUITABLE FOR INSTALLATION IN A UL POLLUTION DEGREE 2 ENVIRONMENT ONLY. THEY ARE UL OPEN CHASSIS (IEC DESIGNATION IP20) DEVICES AND MUST BE INSTALLED WITHIN A SUITABLE ENCLOSURE WHICH AFFORDS MECHANICAL PROTECTION FOR THE DRIVE AND PREVENTS ACCIDENTAL CONTACT OF THE USER WITH POTENTIALLY HARMFUL VOLTAGES.

4.2 CE Installation Requirements

4.2.1 EMC Directive Considerations

MD200 drives are CE Listed and can be used in European Community countries. A Declaration of Conformity appears in Section 10, CE Declarations. MD200 drives meet the requirements of the Low Voltage Directive without modification. Compliance with the EMC (Electromagnetic Compatibility) Directive requires additional equipment and special installation considerations.

A motor drive does not generally function independently. It is a component designed to be integrated into a machine control system, and is generally intended to be installed within another enclosure with other control equipment and devices. It is therefore assumed that the drive is installed in such a manner, and to assure compliance with the EMC Directive, the drive is tested in this configuration. Compliance with the EMC (Electromagnetic Compatibility) Directive requires additional equipment and special installation considerations. The following guidelines must be implemented in addition to standard installation guidelines as described in this manual. Refer to Figure 4.2.1 on the following page for additional information.

1. The drive must be installed in a metallic enclosure designed to contain

radio frequency energy. Basic requirements include RFI gasketing around all door or removable cover joints and continuous welded seams for any enclosure joints.

2. AC line input wiring must be routed in rigid metal conduit or metal jacketed flexible conduit. The conduit must be securely attached to the enclosure with paint or other insulating material removed at the point of attachment to insure positive electrical contact.

10

3. A separate ground conductor must be routed inside the conduit

carrying the AC line conductors. The ground conductor must be solidly connected to the enclosure ground stud.

4. The drive and motor must be solidly grounded to the same point. 5. Install a 1 % minimum impedance line reactor, as required, between

the drive and the power source. 6. An approved Radio Frequency Interference (RFI) filter must be

installed between the drive and the power source. 7. If required, a load reactor with a minimum of 1% impedance may be

installed between the drive and the motor. 8. Shielded power cables must be used to connect the motor to the drive.

The shielded cable must include a separate ground conductor tied to the drive heatsink on one end and the motor ground terminal on the other end. The braided shield or drain wire must be grounded to the drive heatsink.

9. Shielded cable must be used for all control wiring entering or leaving the enclosure that contains the AC drive. The shield must be solidly attached to the drive ground terminal.

10. A ferrite bead must be installed on control wire or cable entering or leaving the enclosure that contains the AC drive.

4.2.2 Low Voltage Directive Considerations

A power system is unique in its safety concerns and the methods used to ensure the safety of people, animals, plant and equipment. The applicable standard for this product family is EN50178: 1998 Electronic Equipment for use in Power Installations. This standard details the design requirements and verification testing required for power electronic systems, including motor drive products, and we have self-certified compliance to the Low Voltage Directive according to this standard.

1. 200-230 V Applications – MD200 drives are dual rated for 200 or 230V operation and carry a higher full load ampere rating when operated at 200V. The drive ratings tables and nameplate list 2 output current ratings. The higher current rating corresponds to the lower voltage rating and the lower current rating corresponds to the higher voltage rating. The result is that the VA rating of the drive stays essentially constant. For example, a 2 HP, 200/230 V rated drive lists output current of 7.8/6.8A. The rated current at 200 V is 7.8A and the rated current at 230V is 6.8A. In order to maintain conformity with CE, the drive must be applied to a motor with both voltage and current rating within the rating of the drive. Using our 2 HP example, if a motor with a 230V rating is applied to the drive, the rated amperes must not exceed the 230V rating of 6.8A. The additional 1.0A (7.8 – 6.8) is not available at the higher voltage.

2. 400-460V Drives – The same conditions apply as described in item 1

above.

3. The drive must be properly grounded by connecting the ground terminal on the drive to a solid earth ground using a conductor with a current rating equal to or greater than the current rating of the AC line feeder conductors. Wire each drive of a multi-drive installation to a common ground point. Do Not daisy chain the ground conductor between drives.

1. Do not use an Earth Leakage (Ground Fault) circuit breaker ahead of

the drive as a means for personnel protection.

2. Current limiting fuses must be used in the AC line feeding the drive even if a suitably sized circuit breaker is used. Refer to Section 4.4.1, Paragraph 4 on Page 13 for fuse recommendations.

12

4.3 Mounting Location

If an open chassis style MD200 AC drive is being installed, it must be panel mounted in a suitable enclosure. Ambient temperature inside the enclosure must be within the drive specification. Refer to Section 8, Specifications for information on MD200 drive losses. NEMA enclosed drives can be mounted in any location within the limits of the NEMA rating of the enclosure. For example, a NEMA 1 enclosed drive must not be mounted in a location where there is a possibility of water entering the enclosure.

!CAUTION

AVOID TOUCHING THE DRIVE HEATSINK DURING AND FOR SEVERAL MINUTES AFTER OPERATION. NORMAL OPERATING TEMPERATURES MAY CAUSE BURNS. INSURE THAT THE MOUNTING LOCATION IS SUITABLE FOR THE EXPECTED TEMPERATURES.

If the drive is installed in another enclosure, the enclosure must be sized according to the heat dissipation of all installed components and additional ventilation supplied, if needed. The enclosure must include a door, cover, etc. to prevent accidental contact with terminals or other drive parts that are at hazardous voltage levels.

In general, the mounting location should meet the following criteria.

• Temperature maintained within the drive specified operating range as

listed in the Specifications, Section 8 of this manual. • Not prone to large temperature swings which could cause condensation. • Humidity maintained within a range that will not result in condensation. • Away from dripping or splashing liquids unless the enclosure carries a

NEMA 4 rating. • Atmosphere is free from corrosive gasses and/or conductive dust. • Not prone to excessive vibration. • Heat sink fins must be oriented vertically. • Airflow must not be obstructed. • Avoid mounting the drive above a heat source (including another drive). • Maintain a minimum of 1 in. (25 mm) horizontal and 2 in. (51 mm) vertical

clearance between a drive and adjacent components including the enclosure wall.

• Install a space heater if the ambient temperature inside the enclosure is likely to fall below 0°C (32°F). A space heater should also be used to minimize condensation if high humidity combined with large temperature swings is anticipated.


13

4.4 Electrical Installation

!DANGER

HAZARD OF ELECTRICAL SHOCK OR BURN! FAILURE TO FOLLOW SAFE ELECTRICAL PRACTICES CAN RESULT IN SERIOUS INJURY OR DEATH. BEFORE COMMENCING INSTALLATION INSURE THAT ALL SOURCES OF POWER ARE TURNED OFF AND LOCKED OUT.

MD200 AC drives must be installed in accordance with the requirements of any national and / or local electrical codes in effect at the point of installation. An experienced electrician, familiar with the handling of solid state power conversion equipment, must perform the installation. In addition to normal electrical safety procedures, the following items must be considered in planning the installation.

4.4.1 Power Wiring

1. Remove all power from sources that feed the AC drive and any associated equipment. Install safety lockout devices in accordance with standard electrical safety practices.

2. Insure that feeder conductors and motor conductors are sized in

accordance with applicable electrical codes. Refer to the drive nameplate or Specifications Section of this manual. If long cable runs between the AC drive and power source are anticipated, insure that the conductors are sized to compensate for voltage drop due to the cable impedance. Failure to do so could result in reduced performance from the AC drive and connected motor.

3. The available short-circuit current at the drive input terminals must not

exceed 5,000 RMS Symmetrical Amperes. Use of a line reactor or isolation transformer may be used if necessary to meet this requirement.

4. The drive should be connected directly to the power system through an

appropriately sized current limiting fuses and a disconnecting means. Fuses should be Bussman Type KTKR rated for 2 Times the drive input current, but not less than 10 Amps. The use of a contactor between the drive and power supply should be avoided. If it is absolutely necessary to install a contactor, take care to insure that the contactor is not cycled rapidly to remove and reapply power to the drive. Removing and reapplying power more often than 6 times per hour may damage the DC bus capacitor precharge circuit and will void the drive warranty.

14

5. Feeder cables to the AC drive must be run in metallic conduit or covered

metal wire-way to minimize radiated electrical interference that could affect nearby electronic devices or cause interference in communication devices. Conduit or wire-way must be properly grounded. In some installations with sensitive electronic equipment, in may be necessary to install a properly sized Radio Frequency Interference (RFI) filter between the AC drive and the power system. Consult the factory for filter recommendations.

6. Do not run motor leads in the same conduit as input power leads.

Switching noise on the motor leads will be coupled into the AC line. 7. Conductors from the drive output to the motor must be run in metallic

conduit or covered metal wire-way to minimize radiated electrical interference which could affect nearby electronic devices or cause interference in communication devices. Conduit or wire-way must be properly grounded. In some installations with sensitive electronic equipment, it may be necessary to use shielded cable for the motor conductors. An installation that must meet CE listing requirements will require shielded cables between the drive and motor.

8. MD200 AC drives use Insulated Gate Bipolar Transistors (IGBTs) in the

inverter section. The extremely fast switching speed of IGBTs can result in potentially damaging voltage spikes being present on the motor leads. This potential increases dramatically with increasing motor cable length. Refer to Section 4.4.2 for additional details.

9. Do not run power cables from one drive-motor combination in the same

conduit or raceway as power cables from another drive-motor combination. This can cause coupling of voltage present in one set of motor leads into another set of motor leads. Potentially damaging voltage transients can occur resulting in damage to the connected motors and a safety hazard can result because even though one of the drives may not be operating, the motor leads can have potentially lethal voltage levels present.

!DANGER

HAZARD OF ELECTRICAL SHOCK OR BURN! DO NOT ROUTE MOTOR LEADS FROM MORE THAN ONE DRIVE-MOTOR COMBINATION IN THE SAME CONDUIT OR RACEWAY. DOING SO MAY CAUSE HAZARDOUS VOLTAGE TO BE INDUCED INTO A SET OF MOTOR LEADS EVEN THOUGH THE DRIVE FEEDING THE MOTOR LEADS IS NOT OPERATING AND HAS POWER REMOVED.


15

10. Do not run control wiring in the same conduit or wire-way with power

wires. Maintain a minimum separation of 36 inches (1 meter) between parallel conduits carrying input power or motor leads and conduits carrying control wires. If it is necessary for power and control wiring to cross, cross at a 90° angle and maintain as much separation as possible.

11. Insure that the correct voltage source is connected to the AC drive input

terminals, as shown in Figure 4.4.1 – 4.4.4, not the output terminals. Connecting a drive to the wrong voltage can cause equipment misoperation and/or failure resulting in a safety hazard. Connecting AC line voltage to the output terminals will destroy the drive and void the warranty.

Connect a ground wire to the terminal provided at the top of the drive. The motor ground should be tied to the same grounding point.

!CAUTION

INSURE THAT THE VOLTAGE OF THE AC DRIVE POWER SOURCE MATCHES THE VOLTAGE RATING OF THE DRIVE NAMEPLATE. CONNECTION OF AN INCORRECT VOLTAGE SOURCE MAY RESULT IN MISOPERATION AND/OR FAILURE OF THE AC DRIVE AND MAY RESULT IN A SAFETY HAZARD. DO NOT CONNECT AC LINE POWER TO OUTPUT TERMINALS (T1, T2, T3).

12. Avoid the use of a contactor between the AC drive and motor. If it is

absolutely necessary to install a contactor between the drive and motor, the contactor must be sequenced so that it is closed before the drive receives a run command and remains closed at all times during drive operation. Improper operation of an output contactor may cause the drive to fail and void the warranty.

4.4.2 IGBT Rated Motors

Operation of IGBT based AC drives such as MD200 drives can result in transient voltages that can be damaging to motors under some conditions. The potential for damage increases as the cable length from the drive to the motor increases. Motors used with MD200 drives should be Inverter duty and suitable for use with IGBT drives. Most motor manufacturers have motor designs suitable for application on IGBT inverters. All Sumitomo Machinery Corp. of America SM-Cyclo® F-frame Gearmotors shipped after August, 1996 are suitable for use on IGBT Inverters. Even though a motor may be IGBT rated, cable length between the motor and drive should be minimized. Refer to Table 4.1 on the following page for recommendations.

If an MD200 drive is installed to operate an existing motor that is more that two years old and/or the motor was previously controlled by a fixed-speed starter, it is highly unlikely that the motor is equipped with IGBT rated insulation. In this event, operation of the drive could result in failure of the motor. A line reactor or transient voltage suppressor installed between the drive and motor may provide the necessary protection. A suggested source of these components is:

4.4.3 Control Wiring

1. All control signals interfacing with the MD200 AC drive must be connected using shielded cable. Analog signals for 0 to 10 VDC, remote speed potentiometer or 4 to 20 mA should be run in shielded, twisted-pair cable. Cable shields for drive inputs must be grounded only at the drive end. The drive chassis is considered ground provided the power supply ground wire is properly terminated at ground screw. A jumper can be placed between any terminal labeled TB2 and chassis ground. All TB2 points are internally connected to each other. Note: TB2 must be connected to chassis ground when terminals TXA and TXB are used for RS485 serial communications. Cable shields for drive outputs must be grounded only at the connected device end.

2. Any relay, contactor or solenoid coil located near the drive, connected to

the drive or fed from the same power source as the drive must be equipped with a transient suppressor on its coil. Consult the device manufacturer for recommended suppressors.

3. A DC relay coil connected to one of the open collector transistor outputs

must be equipped with a flyback diode transient suppressor. The diode must be connected so that its cathode terminal is oriented toward the positive side of the DC voltage. Refer to Figure 4.4.5 below.

4. Refer to Figure 4.4.6 below to become familiar with the drive control

terminal strip. Observe the following when connecting to the control terminal board:

• Strip wires approximately ¼ in (6.5 mm). • Control wiring should be twisted, shielded cable with cable shield

grounded to the drive chassis. • Digital Input DI1 must be connected to common (CM) for the drive to

operate except when Jog Forward or Jog Reverse is selected as the function for Digital Input DI4 and the input is connected to common (CM).

• Refer to typical connection diagrams on the following pages for examples of common control circuits.

4.5.3 Two-Wire Control Separate Run Fwd, Run Rev Contacts

The advantage of using the method for two-wire control shown in Figure 4.5.2 is that unless reverse operation is required, TB13A does not have to be programmed for Reverse thus freeing it for assignment to another function. Two-wire control as shown in Figure 4.5.3 requires that TB13A be programmed for Reverse even if reverse operation is not required.

Figure 4.5.5 – Brake Motor Control

1. A separate brake relay circuit must be used to energize the brake

coil. The circuit must be powered from the AC line and not the AC drive output.

2. The open collector transistor output at TB14 must be programmed for Run to allow a brake to release when the drive starts and to allow the brake to set when the drive stops.

3. This set up is not suitable for applications that involve vertical lifting as no provisions are available to insure that motor torque is available prior to releasing the brake. For these applications, use the NTAC-2000 or AF3100α AC drives.


23

4.6 Explosion-Proof Applications

MD200 drives may be used with an explosion proof motor provided that the motor is UL Listed for use with an AC drive. It must specifically list the Class, Division and Group which is compatible with the location where it will be installed and must include the operating frequency range on its nameplate. Use of the drive with a motor that is not specifically approved for inverter duty will void the listing conditions and may create a safety hazard. Determination of the suitability of the drive and motor combination is the sole responsibility of the user.

24

5.0 Start-Up Instructions

!CAUTION

INSURE THAT THE VOLTAGE OF THE AC DRIVE POWER SOURCE MATCHES THE VOLTAGE RATING OF THE DRIVE NAMEPLATE. CONNECTION OF AN INCORRECT VOLTAGE SOURCE MAY RESULT IN MISOPERATION AND/OR FAILURE OF THE AC DRIVE AND MAY RESULT IN A SAFETY HAZARD. DO NOT CONNECT AC LINE POWER TO OUTPUT TERMINALS (T1, T2, T3).

!CAUTION

TO AVOID DAMAGE TO THE DRIVE, DO NOT APPLY AND REMOVE POWER FROM THE DRIVE MORE FREQUENTLY THAN ONE TIME DURING A TWO MINUTE PERIOD.

!DANGER

HAZARD OF ELECTRICAL SHOCK OR BURN! POTENTIALLY LETHAL VOLTAGES EXIST IN THIS DRIVE AND MAY REMAIN AT A DANGEROUS LEVEL FOR SEVERAL MINUTES AFTER POWER IS REMOVED. BEFORE ATTEMPTING TO SERVICE THIS CONTROLLER, WAIT 3 MINUTES AND MEASURE THE DC BUS VOLTAGE TO INSURE THAT IT IS ZERO.

5.1 Before Applying Power

1. If the drive has not been energized for a long period of time (generally over one year) due to storage or inactivity of the application, the dielectric material of the DC bus capacitors can begin to degrade. The dielectric must be “re-formed” by applying power for 2 hours prior to operating the motor. Failure to reform the dielectric can result in higher than normal leakage current in the capacitor and premature failure of the capacitor.

2. Insure that all wiring is completed in accordance with this manual and

applicable electrical codes. Verify that the input power leads are routed to the proper terminals.

3. Verify that the input voltage and phase matches the drive specifications on

the nameplate or in the Specifications section of this manual.


25

4. Verify that the connected motor ampere rating does not exceed the rated

output current for the drive. Also verify that the motor windings are configured for the proper voltage.

5. Insure that proper fusing is installed in the power circuit feeding the AC

drive.

6. If the driven load can be damaged by reverse rotation, uncouple the motor from the load.

5.2 Applying Power For the First Time

!DANGER

HAZARD OF FLASH BURN OR EYE INJURY! DO NOT STAND DIRECTLY IN FRONT OF THE DRIVE DURING THE APPLICATION OF POWER. INSURE THAT THE ENCLOSURE DOOR OR COVER IS CLOSED AND SECURED.

1. Never stand directly in front of any electrical power device as power is

applied. Miswiring or connection of the wrong voltage can result in catastrophic failure and hazardous release of energy. Close and securely fasten the enclosure door or secure the enclosure cover. The use of approved safety glasses is strongly encouraged.

2. Close the disconnecting means to apply power to the drive.

3. Open the enclosure door or cover to view the LED display on the front of

the drive. If the drive is not receiving a run command, the LED display will indicate as shown below in Figure 5.2.1.

Figure 5.2.1 Display w/Drive Stopped

The 3 center segments of the LED display are illuminated which indicates that the drive is stopped. Note: If you watched the drive power up in spite of the advice to the contrary, the LED will flash a number briefly. This number indicates the parameter set loaded in the drive.

26

5.3 Checking Motor Rotation

The following procedure assumes that the drive has been powered up for the first time and that none of the factory settings have been modified.

1. Press and hold the ∇ button to decrease the frequency setpoint to 00.0

Hz. The left Status LED will illuminate as the setpoint is decreased. The frequency will decrease in 0.1 Hz increments until the next whole Hz value is reached and it will then decrease in 1 Hz increments until the button is released or 0 Hz is reached.

Once 0 Hz is reached, the display will toggle between “00.0” and “- - -“ which indicates that the drive is stopped and zero Hz is commanded.

2. Give the drive a run command as shown in one of the wiring diagrams

shown in the Installation Section. Once the run command is received, the display will show a steady indication of “00.0” which indicates that the drive is in a run state and has a frequency command of 00.0 Hz.

3. Use the ∆ button to increase the frequency setpoint until the motor begins

to rotate. The left Status LED will illuminate as the frequency setpoint is increased. If the ∆ button is held continuously, the frequency will increase in 0.1 Hz increments until the next whole Hz value is reached and it will then increase in 1 Hz increments until the button is released or maximum frequency is reached.

!DANGER


4. Check the direction of rotation. If the direction is correct, no further action

is necessary. If the direction is incorrect. Stop the drive by removing the run command. Remove power from the drive, lock out the disconnecting means and wait for the DC bus capacitors to discharge. Reverse any two of the motor leads connected to terminals T1, T2 or T3 of the drive. Note that reversing the input power leads cannot change the direction. The drive is phase insensitive to the incoming power.


27

5. If the motor was uncoupled from the load during the rotation direction test

procedure, remove all power from the drive and install safety lockout devices as required by electrical codes and good safety practices. Reconnect the motor mechanically to the load.

5.4 Finishing the Start-up

Some programming of the drive will generally be required to optimize the drive’s performance in the application. Programming details are covered in Section 6, Programming. Some things to be considered are:

• Acceleration / Deceleration Time • Use of Analog Input for Speed Command • Configuring the Programmable Digital Inputs • Setting Motor Overload Protection

It is strongly recommended that the entire programming section be studied before attempting to change any parameters. The few minutes spent doing this can save considerable time and headaches when trying to set the parameter values.

28

6.0 Programming the MD200 Drive

Programming the MD200 drive is simple once the proper technique described below is learned. The drive may be programmed by one of three methods.

1. Using the 3 buttons and LED display on the front of an open chassis drive

(or the Operator Interface Module if the optional remote operator device is purchased or a NEMA 1 drive is supplied).

2. Programming the Electronic Programming Module (EPM) using the

optional Portable Programming Fixture.

3. The RS-485 port standard on MD200 drives.

These instructions assume that the programming buttons on the front of the drive are being used. Refer to Section 1, General for a description of the operator interface symbols used in this manual.

6.1 Basic Programming Steps

1. Enter the Program Mode. Enter the programming mode by pressing the Mode button on the front of the drive. This will activate the password prompt. Note: If setting the password value in parameter 44 to zero has disabled the password, this step will be skipped. The right Status LED will blink to indicate that the drive is waiting for the password to be entered.

Press Mode Display Reads “00” Right Status LED Blinks

Password Prompt

2. Set the Password. The Password consists of 3 digits that must be entered using the ∆ and ∇ buttons. The factory default password is 225.

Use the ∆ and ∇ buttons to scroll the display until the correct password value is set. Any number from 001 to 999 may be used. The factory value is 225. Setting a value of 000 in parameter 44 disables the password. Password Prompt


29

3. Enter the Password. Press the Mode button to enter the password set in

the previous step. If an incorrect password was entered, the display will show “Er” for a few seconds as shown below and the password entry process must be repeated from the beginning.

Display after incorrect password entry.

Invalid Password Entry

Otherwise, the programming mode is entered as confirmed the display changing to “P01” which indicates the beginning of the parameter menu. This condition is shown below.

Valid Password entered. Display indicates first parameter number. Use ∆ and ∇ buttons to scroll parameters.

Valid Password Entry (or No Password Set) – Parameters Unlocked

Note: After about 2 minutes of inactivity, parameter access locking will be reestablished and reentry of the password will be required. This can be avoided, if desired, by setting the password value in parameter 44 to 000.

4. Select the parameter. Use the ∆ and ∇ buttons to select the desired

parameter number. Refer to Section 6.4 for a listing of parameter numbers. The example below shows Parameter 19, Acceleration Time.

Use the ∆ and ∇ buttons. Display indicates parameter number.

Parameter Number Selection

30

5. View the parameter value. Press the Mode button while the desired

parameter number is displayed. This will cause the Right Status LED to begin blinking. The current value of the parameter is displayed. Refer to the example below.

Press the Mode button

Parameter Number Action Parameter Value

The example above shows parameter number 19, Acceleration Time, with a value of 20.0 seconds.

6. Change the parameter value. While the Right Status LED is blinking, the

value can be changed using the ∆ and ∇ buttons. Each press will increment the value by one or continuous pressure on the button will cause the value to scroll up or down.

7. Save the parameter value. Press the Mode key to save the new value,

or if no changes were made, restore the old value. Note that this also automatically exits the programming mode. If other parameters are to be set, do so within about two minutes to avoid having to reenter the password.

See Section 6.2 below for additional programming details.

6.2 Setting Parameter Values in Tenths Above 100

Parameter settings, where appropriate, and the keypad speed command can always be adjusted in tenths of units increments from 0.0 to 99.9. Above 100 however, values can be set in whole units or tenths of units, depending on the setting of Parameter 16 - Units Editing. If Parameter 16 - Units Editing is set to WHOLE UNITS (02), the parameter values and the keypad speed command can only be adjusted by whole unit increments above 100. For example, Parameter 19 - Deceleration Time could not be set to 243.7 seconds. It could only be set to 243 or 244 seconds. Likewise, the keypad speed command (set using the ∆ and ∇ buttons) could not be set to 113.4 Hz. It could only be set to 113 or 114 Hz.


31

If, however, Parameter 16 - Units Editing is set to TENTHS OF UNITS (01), parameter values and the keypad speed command can be adjusted in tenths of unit increments up to a value of 1000 (above 1000, whole unit increments only). Each push of the ∆ and ∇ button will adjust the value by one tenth of a unit. If the ∆ and ∇ button is pressed and held, the value will increment by tenths of units until the next whole unit is reached, and then the value will increment by whole units. When a value above 100 is being adjusted by tenths of units, the value is shifted to the left by one digit so that the tenths portion of the value can be displayed. This results in the first digit (reading from left to right) of the value disappearing from the display. Also, the decimal point will blink to indicate that the actual value is above 100. Once the value is no longer being adjusted, the value will shift back to the right and the tenths portion of the value will disappear. In the example below, assume that Parameter 19 - Acceleration Time is presently set to 243.0 seconds and it is being increased to 243.7 seconds.

Press the ∆ button to display tenths.

Present Setting

243 Seconds Action Parameter Value Shifted Left One Digit

Note above that both the Right Status LED and the Decimal Point blink to indicate that tenths are being displayed.

Press the ∆ button seven times.

Present Setting 243.0 Seconds Action New Setting

243.7 Seconds Press the Mode button to save the new value. Note that in the step above, if the ∆ button is pressed and held, the value will begin to increment in whole units after the first whole unit is reached.

32

6.3 Electronic Programming Module (EPM)

Every MD200 drive has an Electronic Programming Module (EPM) installed on the main control board. With open chassis drives, the EPM is located to the left of the LED display and above the programming buttons. It is visible through the front cover and can be removed by grasping it gently with a pair of needle-nose pliers. The EPM stores the factory default and the user program settings (and optionally, an OEM’s parameter settings). The EPM must be present for the drive to operate and the drive will display a fault message “F1” if an EPM is not installed. The removable nature of the EPM offers a couple of advantages. First, if a drive is being replaced with a new unit and the EPM is not damaged, the old EPM can be removed from the drive and installed in the new drive. Second, if many drives are to be programmed with identical parameter values, an EPM can be copied (using the optional Portable Programming Fixture) or parameter values can be downloaded from a computer into the EPM (again using the optional programmer). If OEM settings are not used or the data becomes corrupted, the drive will display a “GF” fault if a RESET OEM or use OEM SETTINGS selection is made in Parameter 48, Program Selection. The user must then either select USER SETTINGS to operate with user entered parameter values, RESET 50 to reset to 50 Hz factory defaults, or RESET 60 to reset to 60 Hz factory defaults. The EPM can be removed and reprogrammed with new OEM settings, if necessary. If the OEM settings, if used, and User settings become corrupted, the user must select RESET 50 or RESET 60 as appropriate for the application.

!CAUTION

DO NOT REMOVE THE EPM WHILE POWER IS APPLIED TO THE DRIVE. DAMAGE TO THE DRIVE AND/OR EPM MAY RESULT.

6.5 Detailed Parameter Descriptions

01 Line Voltage Selection MD200 drives have a range of acceptable input voltages. This parameter allows the drive to be configured for the range of voltage that is applied. For example, an MD240-A75 will work over the range of 380 to 480 VAC, however this is broken into 2 ranges, 380 – 415 VAC (Low) and 440 – 480 VAC (High). Setting this parameter for the correct range improves performance of the drive. Refer to the Table 6.1 below for details.

Note: If this parameter is changed while the drive is running, the new value will not take effect until the drive stops.

02 Carrier Frequency This parameter sets the switching rate of the inverter IGBTs and also controls the drive’s allowed maximum operating frequency. Increasing the carrier frequency will reduce audible motor noise but increase drive losses. Higher carrier frequencies increase the potentially damaging effects of voltage spikes on motor insulation. This effect worsens with increasing motor cable length. Parameter Setting Carrier

03 Start Method

!DANGER

POSSIBLE INJURY OR DEATH SETTING THIS PARAMETER TO “02” OR “04” THROUGH “07” MAY CAUSE A MACHINE TO RESTART UNEXPECTEDLY AFTER A FAULT OR POWER OUTTAGE. THIS VALUE SHOULD NOT BE USED IN CASES WHERE PERSONNEL CAN COME IN CONTACT WITH MOVING APPARATUS.

Continued on next page.


39

Parameter 03 Start Method (continued) Parameter

Setting Action Description

01 NORMAL

The drive will start when the appropriate contact is closed on the terminal strip or when the START key on the optional remote keypad (or integral keypad on NEMA 1 drives) is pressed.

02 START ON POWER UP

The drive will automatically start upon application of input power.

03 START WITH DC BRAKE

When a start command is received, the drive will apply DC Brake Voltage (Parameter 22) for the duration of the DC Brake Time (Parameter 21) prior to starting the motor. This is useful to avoid trying to start a motor that may be coasting.

04 AUTO RESTART WITH DC BRAKING

The drive will respond as described in START WITH DC BRAKE above with the addition that it will attempt to automatically restart up to 3 times after a fault condition or reapplication of power after a power failure.

05 FLYING RESTART 1

Low performance. Slowest synchronization and lowest current level resulting in the smoothest operation.

06 FLYING RESTART 2

Medium performance. Faster synchronization at a higher current level but maintaining smooth operation.

07 FLYING RESTART 3

High performance. Fastest synchronization at the highest current level. Sacrifices smoothness.

Parameter values 02 and 04 through 07 require that the drive be controlled by a 2-wire (maintained run contact) circuit to be functional. The run contact must remain closed during the restart interval for the Auto Restart function to work. The interval between restarts is 15 seconds for setting 04 and 2 seconds for settings 05 through 07. During the interval between restart attempts the display will read “SP” for Start Pending. If all 3 restart attempts fail, the drive will lock out and the display will read “LC” for Fault Lockout and manual reset will be required.

40

04 Stop Method Parameter

Setting Action Description

01 COAST TO STOP

When a Stop command is received, the drive immediately shuts off power to the motor similar to opening a magnetic starter. The motor coasts to stop or can be stopped by a mechanical brake.

02 COAST WITH DC BRAKE

When a Stop command is received, the drive will immediately shut off and activate DC Braking (after a variable, non-programmable, delay of up to 2 seconds). The magnitude of the DC voltage is controlled by parameter 22 and the duration is controlled by parameter 21. Frequent, prolonged use of DC Braking may result in motor overheating and possible damage.

03 RAMP TO STOP When a Stop command is received, the drive decelerates down to stop at the programmed deceleration time (Parameter 20).

04 RAMP WITH DC BRAKE

Similar to “03” above except at 0.2 Hz, DC Brake Voltage is applied for the DC Brake Time to facilitate final stopping of the motor. See parameters 21 and 22.

05 Standard Speed Source This parameter selects the source of the speed reference when the drive is in Standard speed mode. Parameter

Setting Function Description

01 KEYPAD Use the ∆ and ∇ keys to set drive frequency.

02 PRESET SPEED 1

The drive will operate at the frequency set in parameter 31.

03 0-10 VDC Drive frequency is controlled by a 0-10 VDC signal applied between TB5 (+) and TB2 (-).

04 4-20 mA Drive frequency is controlled by a 4-20 mA signal applied between TB25 (+) and TB2 (-).


41

06 TB14 Open Collector Output Function This parameter selects the function for the open-collector transistor output at terminal TB14. Open collector transistors can directly drive the input of most “sinking” type digital inputs of Programmable Logic Controllers or embedded controllers. The power supply common of the external device must be connected to TB2 of an MD200 drive. Open collector transistors can also be used to drive external relays to switch larger loads or loads with higher voltage requirements. When the transistor turns “on”, TB14 is pulled to common and current can flow from TB14 (+) to TB2 (-). Open collector transistors can only be used to switch DC loads. Parameter


01 NONE The output is disabled.

02 RUN

On when the drive is running. Off when the drive stops either normally or due to a fault. This is useful for remote run indication or to sequence a motor mechanical brake.

03 FAULT On indicates normal operation. Off indicates a fault or no power applied.

04 INVERSE FAULT

On indicates a fault. Off indicates normal operation or no power.

05 FAULT LOCKOUT

On during normal operation. Off after three failed restart attempts or if no power is applied.

06 AT SET FREQUENCY

On if the drive output frequency is between ± 0.5 Hz of the set frequency.

07 ABOVE PRESET SPEED 3

On if the output frequency exceeds the value set in Preset Speed 3 (parameter 33). Off if the output frequency is equal or less than Preset Speed 3.

08 CURRENT LIMIT On if the output current exceeds the Current Limit setting (parameter 25), otherwise Off.

09 AUTOMATIC MODE

On if an Automatic (terminal strip) speed reference is active. Off if a Standard speed reference is active. See parameter 5.

10 REVERSE On when reverse rotation is active, otherwise Off.

42

08 TB30 Analog Output Terminal TB30 provides a 0-10 VDC or 2-10 VDC signal proportional to Output Frequency or Load as selected in this parameter. Parameter


01 NONE The output is disabled. 02 0-10 VDC FREQ 0-10 VDC from 0.0 Hz to parameter 40 value. 03 2-10 VDC FREQ 2-10 VDC from 0.0 Hz to parameter 40 value. 04 0-10 VDC LOAD 0-10 VDC from 0% to parameter 41 value. 05 2-10 VDC LOAD 2-10 VDC from 0% to parameter 41 value.

Note: The 2-10 VDC signal can be converted to 4-20 mA by connecting a resistor in series with the signal so that the total resistance (Resistor + Load Input Impedance) is 500 ohms. The output cannot be used with “Loop Powered” devices that derive their control power from the 4-20 mA signal.

09 TB31 Analog Output Similar to TB30 above plus Dynamic Braking module control. Parameter


01 NONE The output is disabled. 02 0-10 VDC LOAD 0-10 VDC from 0% to parameter 41 value. 03 2-10 VDC FREQ 2-10 VDC from 0% to parameter 41 value.

04 DB CONTROL Provides the trigger that activates the optional, external Dynamic Braking module.

The same note related to 4-20 mA as shown in TB30 applies.


43

10 TB13A Function Select This parameter is used to select the function of digital input terminal TB13A. Connecting TB13A to TB2 (common) activates the programmed function. Parameter

Setting Function Description (When Active)

01 NONE The input is disabled.

02 0-10 VDC Selects 0-10 VDC connected between TB5 (+) and TB2 (-) as the frequency reference.

03 4-20 mA Selects 4-20 mA connected between TB25 (+) and TB2 (-) as the frequency reference.

04 PRESET SPEED 1

Selects preset speed 1 (parameter 31) as the frequency reference.

05 RUN REVERSE*

Two-wire control. Close to Run Reverse. Open to stop the drive. Programming this value forces TB12 to become Run Forward and TB1 must be connected to TB2 for the drive to operate.

06 START REVERSE*

Three-wire control. Momentarily close to start in the reverse direction. Momentarily open (disconnect) TB1 from TB2 to stop the drive. Programming this value forces TB12 to become Start Forward.

07 EXTERNAL FAULT

TB13A must be wired to TB2 through a normally closed contact. Opening the contact causes the drive to fault trip. This function is useful if a motor thermostat is used for over temperature protection.

08 REMOTE KEYPAD

Selects the Remote keypad (open chassis drive) or local keypad NEMA 1 drive as the control source. See parameter 14.

09 DB FAULT When this input is activated by the optional dynamic braking module, the drive will trip and the display will indicate “dF”.

10 AUXILIARY STOP

When the input is opened, the drive will decel to stop at the time set in parameter 42, Accel/Decel 2. If the input is activated after a stop command and the Stop Method is set to Ramp, action is as above. If the Stop Method is set to Coast, the motor coasts to stop.

* The drive will not operate in reverse unless parameter 17 is set properly.

11 TB13B Function Select

!DANGER

POSSIBLE INJURY OR DEATH THE JOG FUNCTION OVERRIDES THE FUNCTION OF ALL STOP INPUTS. CLOSING A JOG INPUT WILL CAUSE THE DRIVE TO RUN EVEN IF THE STOP INPUT IS OPEN.

!CAUTION

JOG REVERSE WILL CAUSE THE DRIVE TO OPERATE IN REVERSE EVEN IF ROTATION DIRECTION (PARAMETER 17) IS SET TO FORWARD ONLY.

Parameter





04 PRESET SPEED 2


05 DECREASE FREQUENCY

Causes frequency to decrease as long as input is closed or until minimum frequency is reached. Use in conjunction with Increase Frequency function for TB13C to achieve a Motor Operated Pot (MOP) function.

06 JOG FORWARD

Causes Jog operation in the forward direction. Drive frequency is controlled by Preset Speed 2 (parameter 32). Note: Jog overrides a stop command or input.

07 JOG REVERSE

Causes Jog operation in the reverse direction. Drive frequency is controlled by Preset Speed 2 (parameter 32). Jog overrides a stop input and will cause reverse rotation even if Parameter 17 is set to FORWARD ONLY.

08 AUXILIARY STOP

When the input is opened, the drive will decel to stop at the time set in parameter 42, Accel/Decel 2. If the input is activated after a stop command and the Stop Method is set to Ramp, action is as above. If the Stop Method is set to Coast, the motor coasts to stop.

Note: If a Jog command is given during drive operation, the drive will shift to Jog speed. The drive will stop when the Jog command is removed.


45

12 TB13C Function Select This parameter is used to select the function of digital input terminal TB13B. Connecting TB13C to TB2 (common) activates the programmed function. Parameter





04 PRESET SPEED 3


05 INCREASE FREQUENCY

Causes frequency to increase as long as input is closed or until maximum frequency is reached. Use in conjunction with Decrease Frequency function for TB13B to achieve a Motor Operated Pot (MOP) function.

06 EXTERNAL FAULT

Sets TB13C as a normally closed external fault input. If TB13C is open with respect to TB2, the drive will fault trip.

07 REMOTE KEYPAD

Selects the optional Remote keypad (open chassis drives) or Local keypad (NEMA 1 drives) as the control source. See parameter 14, Control.

08 DB FAULT When this input is activated by the optional dynamic braking module, the drive will trip and the display will indicate “dF”.

09 ACCEL / DECEL 2

Selects the acceleration and deceleration time programmed into Parameter 42, Accel/Decel 2.

13 TB15 Open Collector Output This parameter selects the function of open-collector output TB15. It has the same selections as TB14 described in parameter number 6.

46

14 Control This parameter selects the source of the Start/Stop and direction commands. Parameter


01 TERMINAL STRIP ONLY

The drive will only respond to Start/Stop and direction commands from the terminal strip.

02 REMOTE KEYPAD ONLY

The drive will only respond to Start/Stop and direction commands from the optional keypad.

03 TERMINAL STRIP or KEYPAD

Terminal TB13A or TB13C can be used to manually switch between Terminal Strip and Keypad control. This can be used as a Manual- Auto or Local-Remote function.

Notes: 1 - The Stop button on the optional remote keypad is always active. 2 - If the optional remote keypad is not installed, the terminal strip is always

active regardless of the setting of this parameter.

15 Serial Link This parameter configures the drive for serial communications. Selecting one of the settings below which includes a timer function activates a “watchdog timer”. If no communications with the drive are conducted within about 10 seconds, the drive will automatically stop. During set up or troubleshooting, it may be desirable to disable the watchdog timer but, for safety reasons, the timer should be used when the serial port is used to control the drive.

!DANGER

POSSIBLE HAZARDOUS SITUATION SETTING THIS PARAMETER TO “03” ENABLED WITHOUT TIMER DISABLES THE WATCHDOG TIMER. A FAILURE OF THE SERIAL LINK MAY PREVENT THE DRIVE FROM RECEIVING A STOP COMMAND.

The MD200 serial port is formatted as an RS-485 port for enhanced noise immunity. All communications takes place using the Modbus® protocol. The device communicating with an MD200 drive must be configured to match the communication settings selected for the drive as shown in the table on the following page. Further discussion of the Modbus protocol is beyond the scope of this manual. Modbus is a registered trademark of Schneider Automation, Inc.

Parameter 15, Serial Link (continued) Parameter


01 DISABLED The serial link is disabled and cannot be used to control the drive.

02 9600, 8, N, 2 ENABLED WITH TIMER

The serial link is enabled at 9600 baud, 8 data bits, no parity and 2 stop bits and the watchdog timer is active.

03 9600, 8, N, 2 ENABLED W/OUT TIMER

The serial link is enabled at 9600 baud, 8 data bits, no parity and 2 stop bits and the watchdog timer is not active.

04 9600, 8, E, 1 ENABLED WITH TIMER

The serial link is enabled at 9600 baud, 8 data bits, even parity and 1 stop bit and the watchdog timer is active.

05 9600, 8, E, 1 ENABLED W/OUT TIMER

The serial link is enabled at 9600 baud, 8 data bits, even parity and 1 stop bit and the watchdog timer is not active.

06 9600, 8, O, 1 ENABLED WITH TIMER

The serial link is enabled at 9600 baud, 8 data bits, odd parity and 1 stop bit and the watchdog timer is active.

07 9600, 8, O, 1 ENABLED W/OUT TIMER

The serial link is enabled at 9600 baud, 8 data bits, odd parity and 1 stop bit and the watchdog timer is not active.

16 Units Selection Above 100 This parameter allows for frequency and parameter selection in either whole units or tenths when the value being set is above 100. Parameter


01 TENTHS

Values less than 100 are always able to display to tenths of units resolution. If this setting is used for this parameter, values above 100 can be displayed in tenths using the ∆ or ∇ buttons until the next whole unit is reached.

02 WHOLE Values above 100 will always change in one unit increments.

48

17 Rotation Direction Parameter


01 FORWARD ONLY

The drive will not respond to a Run Reverse or Start Reverse input, however, Jog Reverse can still cause reverse rotation. Assignment of Jog Reverse to TB13B function should not be made if the driven load can be damaged by reverse operation.

02 FORWARD AND REVERSE

The drive is free to rotate in either direction as called for by the input commands.

19 Acceleration Time This parameter sets the acceleration rate for all speed reference sources (keypad, speed pot, 0-10 VDC, 4-20 mA, jog and preset speeds). This setting is the time to accelerate from 0 Hz to BASE frequency (60 Hz or 50 Hz). Set the desired value using the ∆ or ∇ button.

20 Deceleration Time This parameter sets the deceleration rate for all speed reference sources (keypad, speed pot, 0-10 VDC, 4-20 mA, jog and preset speeds). This setting is the time to decelerate from BASE frequency (60 Hz or 50 Hz) to 0 Hz. Set the desired value using the ∆ or ∇ button. Note that a value of “00” cannot be set.

21 DC Brake Time This parameter sets the duration of the application DC Braking voltage to the motor in seconds. Keep in mind that shorter is better because of the heating effect of DC Braking voltage.

22 DC Brake Voltage This parameter sets the magnitude of DC Braking voltage applied to the motor as a percentage of DC Bus voltage. The point at which the DC braking is activated depends on the selected Stop Method (Parameter 04).


49

If COAST WITH DC BRAKE is selected in Parameter 04, Stop Method, DC braking is activated within 2 seconds of the drive receiving a stop command. If RAMP WITH DC BRAKE is selected in Parameter 04, DC braking will activate when the frequency decreases to 0.2 Hz.

23 Minimum Frequency This parameter sets the minimum output frequency of the drive for all speed reference sources except the Preset Speeds (Parameters 31 – 37). This parameter also sets the drive output frequency which corresponds to the minimum value of 0-10 VDC and 4-20 mA analog input signals. If the parameter is changed while the drive is running, the new value will not take effect until the drive stops.

24 Maximum Frequency This parameter sets the maximum output frequency of the drive for all speed reference sources and is used with the Minimum Frequency (Parameter 23) to define the operating range of the drive. If the High Frequency drive option is used, the highest Maximum Frequency setting is determined by the Carrier Frequency setting (Parameter 02).

!DANGER

POSSIBLE SEVERE INJURY OR DEATH! DO NOT OPERATE A MOTOR ABOVE ITS RATED SPEED WITHOUT APPROVAL FROM BOTH THE MOTOR AND DRIVEN MACHINE MANUFACTURER.

This parameter also sets the drive output frequency which corresponds to the maximum value of 0-10 VDC and 4-20 mA analog input signals.

25 Current Limit This parameter sets the maximum allowable output current of the drive, which also determines the torque capability of the motor. The maximum setting is either 180% or 150%, depending upon the setting of the Line Voltage Selection (Parameter 01).

50

The drive will enter current limit when the load demands more current than the Current Limit setting, which results in a loss of synchronization between the drive and the motor. To regain control of the motor, the drive will automatically reduce the output frequency in an attempt to allow the motor load to decrease. The drive will return to the required operating frequency after the overload condition passes.

26 Motor Overload MD200 drives are equipped with an overload sensing and protection function to protect the drive and are approved by UL for solid state motor overload protection. No additional overload protective device is required. The overload function protects the drive and connected motor, from a sustained over current condition. The operation of this function allows the drive to deliver up to 150% of its rated current for one minute and higher currents for shorter periods of time. If the overload condition persists for a longer period than allowed, the drive will trip and indicate an Overload fault. The value in this parameter is expressed as a percentage of the motor current divided by the drive current rating. For example, if a motor rated for 3.4 A is connected to a drive rated 4.8 A the ratio percentage is calculated as shown below

Once the value is calculated, set the value in this parameter.

27 Base Frequency This parameter determines the Volts per Hertz (V/Hz) ratio by setting the output frequency at which the drive will output full voltage to the motor. In most cases, the Base Frequency should be set to match the motor’s rated frequency, usually 50 Hz or 60 Hz.

28 Fixed Boost Fixed Boost is used in applications that require high starting torque. This increases starting torque by increasing the output voltage at lower frequencies (below 30 Hz for 60 Hz base frequency) resulting in an increased V/Hz ratio.

D

MRatio I

51

Note: Since the increased V/Hz ratio is present at low frequencies, increased motor heating will result. The boost value should be kept to the minimum value that produces the desired result and continuous low speed operation should be minimized. Refer to the Acceleration Boost parameter below for a possible better solution if long periods of low speed operation are required.

29 Acceleration Boost Acceleration Boost is similar to Fixed Boost described above except the increased V/Hz ratio is automatically disabled after the drive reaches the set output frequency. This minimizes heating caused by a higher V/Hz ratio at low speeds.

30 Slip Compensation A typical NEMA Design B AC induction motor operates with a Slip value of between 2 and 3 percent. This means that as motor load increases from no load to full load, the motor will “Slip” or decrease speed by about this value. Most applications are not adversely affected by this small speed change. If motor speed must be maintained more closely, Slip Compensation may be sufficient to achieve the desired results. Slip compensation causes the drive to boost output frequency beyond the set frequency as motor load increases. The effect is that the actual motor speed does not decrease as load increases. The following example shows how to set the value for a motor with a 1750 RPM full load speed. Note: Synchronous speed is 1800 RPM for a 4-pole motor.

Set this parameter by entering the appropriate value in this parameter. For the example above, use either 2.7% or 2.8%. Note that the value can be adjusted as necessary to achieve the desired results.

31 – 37 Preset Speed #1 to Preset Speed #7 Preset Speeds (Frequencies) are active only when the drive is from the control terminal strip. The speeds are selected by connecting one or more terminals TB13A, TB13B and/or TB13C to common (TB2). The terminals must be programmed for Preset Speed 1, 2 or 3 for preset speed selection to work. See Parameters 10, 11 and 12 for details. A maximum of 7 preset speeds can be selected using all three inputs. The use of two inputs allows selection of 3 preset speeds (Speed 1, Speed 2 and Speed 4). The use of one input allows selection of 1 preset speed (Speed 1). The truth table below shows the selection pattern. A “0” means that the terminal is open and a “1” means that the terminal is connected to TB2.

No. 37) 1 1 1 Note 1: If all inputs are open, the drive frequency is determined by the setting for Parameter 05, Standard Speed Source. Note 2: If a TB13 terminal is programmed for a function other than preset speed selection, it is considered open in regards to the speed selection truth table above.

38 Skip Bandwidth MD200 drives have two skip frequencies that can be used to prevent operation at speeds which cause mechanical resonance and excessive noise and/or vibration in a mechanical system. Setting a value other than 0.0 enables the skip frequency function. The value set for Preset Frequency No. 6 is the starting point for the first skip frequency band and Preset Frequency No. 7 is the starting point for the second skip frequency band. The Skip Bandwidth set in this parameter is added to the starting point. Continuous operation within the skip band is prohibited although the drive will accelerate or decelerate through the band.


53

If the drive is operating at a frequency below the band and the frequency reference would result in operation within the skip band, the frequency will increase to the bottom of the band and remain there until the frequency reference calls for a frequency above the band. Similar operation occurs when the frequency is being decreased. Consider the following example. A machine has a critical frequency of 23 Hz and it is desired to avoid operation within ± 3 Hz of this frequency. Set Parameter 36, Preset Frequency No. 6 for 20.0 Hz and set this parameter for 6.0 Hz.

39 Speed Scaling This parameter scales the display to indicate speed or user units other than frequency. The parameter should be set to the desired display value when the drive is outputting 60 Hz. The maximum setting of this parameter is 6500 and the highest value than can be displayed is 6553.6. Determine the value of this parameter as shown in the following example. Assume a conveyor is moving at 175 feet per minute when the drive is operating at 60.0 Hz. Setting this parameter to 175 will result in the display indicating 175 when the drive is operating at 60.0 Hz, 87.5 when the drive frequency is 30.0 Hz, etc. If the maximum display value is exceeded, the display will flash “999” to indicate an over range condition.

40 Frequency Scaling This parameter scales the analog output signal at TB30 when it is configured for a frequency output. This setting is the output frequency indicated when the output signal measures 10 VDC. For example, suppose a 0-5 VDC signal is required to indicate 0-60 Hz operation. The normal indication would be 0-10 VDC for 0-60 Hz. Since we want half of the maximum voltage output at 60 Hz, we scale the output by selecting 120 Hz for maximum voltage output. The result is the value of this parameter is set to 60.

54

41 Load Scaling This parameter scales the analog output signal at TB30 or TB31 when it is configured for a load output. This setting is the output current in percent of maximum when the output signal measures 10 VDC. For example, suppose a 0-10 VDC signal is required to indicate 0-150% load. Set the value of this parameter to 150 which produces 10 VDC output when the load is 150% of rated.

42 Accel / Decel Time 2 This parameter sets the second acceleration and deceleration rate of the drive. The function of the programmable digital inputs must be modified to select the alternate Accel / Decel time. Refer to parameters 10, 11 and 12 for details. Note that unlike the primary acceleration and deceleration times which are independently programmable, the value set in this parameter affects both acceleration and deceleration.

43 Serial Address MD200 drives are equipped, as standard, with an RS-485 serial communications port. The ModBus® communication protocol is used. RS-485 supports up to 32 drives on a single communication channel and each drive must be assigned a unique address. This parameter sets the drive address if the serial communication port is used to communicate from a computer or PLC to the drive. Choose a value from 1 to 247.

44 Password Parameter settings in MD200 drives can be protected from accidental change by using a 4-digit password. If this parameter is set to anything besides “000”, the user must enter the password as described in Section 6.1. Note: The default password is “225”. When initially configuring a drive, it is recommended that the password be disabled. This avoids the inconvenience of reentering the password is the drive sits idle for more than a couple of minutes.


55

47 Clear Fault History MD200 drives can store the last 8 faults (viewed in Parameter 50) even if the fault is cleared by resetting the drive (cycling power). It is not necessary to clear the fault history because a later occurring fault will automatically overwrite any existing information, however, if desired, the fault history can be cleared. Two values are possible, “01”, the default, retains the fault history. Clear the history by setting the value to “02” and pressing the Mode key. This parameter automatically returns to “01” the next time it is accessed.

48 Program Selection This parameter is used to select which set of parameter values is used by the drive. It also allows parameters to be reset to their original factory shipped state for either a 50 Hz or 60 Hz base frequency. The parameter can also be used to select an optional OEM entered parameter set. Note that the OEM parameter set must be entered into the EPM module using the optional Portable Programming Fixture. The following settings are available: Parameter


01 USER SETTINGS

The drive will operate according to the user’s programmed values for the parameters.

02 OEM DEFAULTS

The drive will operate according to the optional OEM default settings. When operating in the OEM mode, the parameter values can be viewed but not changed. The LED display will flash the fault message “GE” if a change is attempted. The display will flash “GF” if no OEM parameters have been programmed.

03 RESET OEM

Copies OEM settings into the User Settings. After execution, the settings can be changed if desired without affecting the OEM defaults. If no OEM settings are programmed, the display flashes “GF”.

04 RESET 60 Resets the parameters to the factory default for 60 Hz base frequency operation.

05 RESET 50 Resets the parameters to the factory default for 50 Hz base frequency operation.

56

50 Fault History (Read Only) This parameter stores up to 8 faults that have previously occurred in order of occurrence. The first fault shown is the most recent. Use the ∆ and ∇ buttons to scroll through the list. An indication of “_ _” indicates that there is no fault. Refer to Section 7, Troubleshooting for a listing of fault codes.

51 Software Version (Read Only) This parameter shows the version of software installed in the drive. Version information may be important when contacting Technical Support. The software version is displayed in two parts which alternate. The first part is the software version and the second part is the revision number. For example, if the display shows "64-“ and “-02” this indicates that it is revision 2 of version 64.

52 DC Bus Voltage (Read Only) This parameter displays the DC Bus voltage in percent of nominal rating. DC Bus voltage for a powered but not operating drive is about 1.4 time the applied line voltage (except for 120 VAC input drives which use a voltage doubling circuit). This value is referenced to the drive nameplate voltage rating. For example, if the drive nameplate is 240V and this parameter value is 95, the DC Bus voltage is about 321 VDC.

53 Motor Voltage (Read Only) This parameter displays the drive output voltage as a percent of the nameplate rating similar to the operation of Parameter 52 above.

54 Motor Load (Read Only) This parameter displays motor load as a percent of the drive output current rating on the nameplate.

If a fault condition causes the drive to shut off, the display will indicate a fault code that provides information helpful in determining the reason for the shutdown. The fault code is displayed until the drive is reset and the fault code is recorded in the Fault History parameter (50) until the history is cleared or until another fault occurs. The Fault History parameter can store the last 8 faults in order of occurrence as described in Section 6.7. Table 7.1 below shows the meaning of fault codes that are displayed and offers suggestions as to the cause and possible corrective action.

Table 7.1 Fault Messages

Fault Code

Description Possible Causes

AF High Temperature Fault

Insure that the ambient temperature is within the drive rating. If the drive is equipped with a fan, insure that the

fan is rotating. Insure that foreign material has not obstructed air

flow over the heatsink or fan (if used).

CF Control Fault A blank or defective EPM is installed in the drive. The EPM installed in the drive has incompatible

data. Reset to factory using Parameter 48. F1 EPM Fault The EPM module is missing or damaged.

cF Incompatibility Fault

An EPM with a different parameter version is installed. Change EPM or perform factory reset.

GF Data Fault

User or OEM Data in the EPM is corrupted. Execute a Reset 60 (60 Hz) or Reset 50 (50 Hz) command in Parameter 48. An attempt was made to Reset OEM defaults and

no OEM default parameters are loaded.

EF External Fault A digital input terminal (TB13A or TB13C) is set for

External Fault and the terminal is Open with respect to TB2.

LF Low DC Bus Voltage

Low line voltage. Check the AC line voltage to insure that it is within the drive rating. Momentary dip in line voltage. Starting of large

motors on the same power supply can momentarily cause a drop in line voltage. Parameter “01” Line Voltage may be set

incorrectly. If line voltage where the drive is installed is at the lower end of the drive rating, this parameter should be set to LOW.

!DANGER


Table 7.1 Fault Messages (Continued)

Fault Code


HF High DC Bus Voltage

Deceleration time too short. Lengthen the deceleration time or use an optional Dynamic Braking module if short decel time is required. Overhauling load. The load is trying to over-speed

the motor as a hoist lowering or downhill conveyor. Contact the factory for assistance. High AC line voltage. Line voltage may increase if

large loads are not operating. Investigate the possibility of changing transformer taps or open the disconnecting means to the drive during shutdown periods. AC line transients. If this fault occurs regularly at

certain times of day, investigate automatic switching of power factor correction capacitors. Installation of an AC line reactor between the drive and power source may help.

OF Output Fault

Phase to phase or Phase to ground fault. Verify that the motor and motor leads are not shorted or grounded. If the motor is to be meggered, it must be disconnected from the drive first. Boost settings too high. If Fixed Boost or

Acceleration Boost parameters are set too high, excessive current can cause this fault. Reduce the setting(s). Defective output transistor. Disconnect the motor

from the drive and attempt to start the drive. If the fault occurs with no motor connected, the drive is defective and must be replaced. Before installing a new drive, check the motor and wiring to insure that the new drive will not be damaged.

Table 7.1 Fault Messages (Continued)

Fault Code


PF Current Overload Fault

Drive and/or motor undersized for the application. Verify that the motor starts and accelerates to the required speed when commanded. Measure motor current with a clamp on ammeter or display percent loading using Parameter 54. If the load is excessive, the load must be reduced or a larger drive/motor package must be installed. Binding in driven load. Insure that the driven load

is not being obstructed either by a jam condition or because of faulty bearings. Brake not releasing. If the MD200 drive is

operating a motor equipped with an electrically released brake, the brake coil must be wired to a separate source of power and not to two of the motor leads. AC drives control voltage and frequency and will produce insufficient voltage to release the brake at low speeds.

UF Start Fault

A run command is present when power is applied to the drive. For safety reasons, the drive is shipped with Parameter “03”, Start Method, set to Normal. If the drive must start when power is applied, change the Start Method parameter to Start on Power Up or Auto Restart. If either of these two selections are made, insure that personnel cannot be in contact with moving parts.

dF Dynamic Braking Fault

The duty cycle of the dynamic braking module is too high which could possibly cause the DB resistors to overheat. Reduce the duty cycle by extending the deceleration time or by reducing the frequency of stopping.

SF Single Phase Fault

Single-phase power is applied to a drive which is not rated for single-phase input. If only single-phase power is available, select a drive model which allows single-phase operation. If the power source is three-phase, an experienced electrician should verify the integrity of incoming line connections. Check AC line fuses to determine if one fuse has opened.

F1-F9 Fo

Internal Faults

A problem has been detected on the drive control board. Contact the factory for assistance.

To clear a fault condition, issue a stop command or cycle power to the drive. If the condition which caused the fault has passed, the drive will reset.

Enclosures housing MD200 drives must be sized to dissipate the expected heat loading of the drive or drives which it contains plus the heat loading of other devices. If an optional Dynamic Braking module is installed, the wattage rating of the DB module and the braking duty cycle must be considered in selecting the enclosure. Additional ventilation in the form of forced air or air conditioning may be required. If mounting the enclosure containing the drive in an outdoor location, the heat gain, and temperature increase, due to solar radiation must be considered. Also, if outdoor mounting is required, low temperatures must be considered. The use of a thermostatically controlled space heater may be required.
