2.2 Description of frequency inverter MFC 20/21

The description and installation instructions are intended to inform the engineer planning the master lift control about the use of the frequency inverter range MFC 20/21.

The frequency inverter is a pulse inverter with DC link, latest microprocessor technology and IGBT solid-state power components.

Power vector control and field-oriented motor management by motor-mounted rotary encoder permits maximum dynamic performance and, therefore, load-independent high quality run performance.

The stopping accuracy quality of load-dependent u/f motor control by encoder-less operation (modernization jobs) is lower.

The drive system consisting of MFC 20/21 frequency inverter and „ThyssenKrupp motor“ is factory-adjusted.

The motor shall not be adapted to the frequency inverter prior to powering the lift installation on.

Only check whether the adequate motor (see name plate) and encoder type (number of increments) are selected.

Display and/or selection of correct values by parameter P 40 (motor) and P 96 (encoder).

Try to determine the pulse number per revolution through parameter P 105 if unknown. (See chapter 5.4.2 Display parameters, page 5-31).

Adaption in the course of putting the frequency inverter into operation for third-party motors. (See chapter 7 Modernization , page 7-1)

The main features of the frequency inverter range MFC 20/21 consists of the following points:

• PWM control with 16 kHz pulse frequency, i.e. no motor noise. Automatic reduction of frequency by overload.

• Peak current is available for approx. 10 s during operation.

• Connection of contactors on mains (before the frequency inverter) or motor side (after the frequency inverter). (See chapter 9.4.1 Run contactors on motor side page 9-7 / 9.4.2 Run contactors on line side page 9-8).

• No integrated fuses. Therefore adaptation of the installation fuses to inverter output (see chapter 2.2.4.2 Type data, page 2-7).

• Separate control voltage (230 V) required.

• Regenerative energy is converted to heat by external brake resistor.

• Presetting of running characteristic by short run computer. Monitoring of reference/actual speed. Monitoring is not effective at “vi” (inspection speed).

• Isolated voltage detection.

• Device connection without removing of covers. All cable terminals are on topside of device; control terminals are accessible from front side.

• Low-noise operation thanks to use of DC ventilators.

• Speed to 2.0 m/s with geared drives

to 3.5 m/s with gearless drives

to 1.25 m/s with third-party motors (modernization jobs)

Observe minimum floor-to-floor distances. (See chapter 4.8.3 Diagram for determining the minimum floor-to-floor distances, page 4-10).

12.8.2004 MFC 20_21_ENG / Version 01/04 2-3




2.2.1 Naming

The frequency inverter range for asynchronous motors is named MFC 20

The frequency inverter range for asynchronous motors is named MFC 21

The main distinctive feature is the software used.

In this description it is referred to MFC 20 only. The same features apply to MFC 21.

2.2.2 Warnings

• Works on the frequency inverter shall only be performed by trained and qualified personnel. They must observe the appropriate rules for prevention of accidents and shall be informed about the danger of electric current to be considered. (See chapter 1.2 General safety instructions, page 1-2.)

• Frequency inverters are electronic devices and, therefore, not fail-safe. The owner of the installation is responsible for the safety of persons and protection of material property.

• Requirements for the installation and operation of electric systems (EN 50178 / VDE 0160 and VDE 0110) must be observed for mounting of frequency inverter. Protective measures to be taken acc. to local conditions and regulations.

• Electric energy may still be present after shutting off the inverter. (Charge of DC link capacitors). This applies to defective devices in particular. A warning to this effect is to be displayed on the device and must also be present in the operating manual of the lift control.

• The integrated heat sink or other components, too, may still have a temperature > 60 °C during operation or shortly after powering off the device.

• The external brake resistor may have a temperature > 200 °C during operation.

• The brake resistor should preferably be fitted on the control cabinet roof. Observe that there is no combustible material above the brake resistor.

• Wall-mounted brake resistors shall not be fitted on / below combustible materials.

• Observe that there is no combustible material above and in immediate vicinity of the brake resistors.

These warnings do not claim to be complete.

2.2.3 Mounting instructions

The following points are to be observed: The frequency inverter is a building part, which is designed in protection class IP 20.

Mounting dimensions and required free space for ventilation see dimension sheet (see chapter 2.5 Dimension drawings drawings, page 2-222).

Vertical mounting position is to be observed and free air inlet/outlet at heat sink provided.

Ventilation apertures are required with the frequency inverter installed in a control cabinet. Power loss see technical data.

Respective measures are required if polluted cooling air impairs the operation of the frequency inverter (installation of air filter and regular cleaning, for example).

2.2.5.5 Leakage current Interference suppression by Y capacitors between phase and protective earth conductor of frequency inverter and line filter.

The arising leakage current is > 3,5 mA.

Therefore cross-section of the protective earth conductor of supply cable shall be at least 10 mm² Cu in accordance with EN 50 178 (VDE 0160), chapter 5.3.2.1: April 1998.

2.2.5.6 Fault current Fault current with zero-frequency quantity can arise in case of earth contact in frequency inverter. Therefore the leakage current of the Y capacitors make use of protective equipment against standard fault current (FI) (pulsating current sensitive) impossible.

The operation manual shall inform that use of protective fault current equipment only does not fulfil the requirements of EN 50 178 (VDE 0160), chapter 5.2.11.2: April 1998.

AC-DC sensitive fault current protection is recommended. Connection notes of manufacturer are to be observed.

Also see 2.4.44 Line filter, page 2-211

2.2.5.7 Discharge time of DC link capacitors The recommended residual voltage of 60 V after 5 seconds as required acc. to VDE 0113, part 1, chapter 6.2.3: (June 1993) is not complied with. A warning to this effect is given on the frequency inverter.

A quick forced discharge by manual short-circuiting is not permissible.

12.8.2004 MFC 20_21_ENG / Version 01/04 2-9




2.2.5.8 Electronic Ground Electronic ground (electronic zero) is electrically connected with the protective earth conductor (PE).

2.2.5.9 Run contactors The run contactors can be connected on the line side (before the frequency inverter) or on the motor side (after the frequency inverter).

Contactors with 50 Hz AC coil excitation can be used if connected on line side. The shielded motor-cable can also be run to the frequency inverter in accordance with the EMC requirements and the shielded motor cable connected by suitable cable clips.

Coils with DC coil excitation shall be used for motor side connection. This guarantees delayed release of contactors. The shielded motor cable can be run to the run contactor in accordance with the EMC requirements and the shielded motor cable connected by suitable cable clips. Short and twisted cabling of the motor lines running to 2. run contactor is recommended. (Also see 2.4.2 Mounting instructions, page 2-188)

The contactor coils should be provided with overvoltage protection elements (RC element or free-wheeling diode).

2.2.5.10 Internal fan The internal fan for cooling the heat sink is turned on during every run.

If the heat sink temperature exceeds a certain value, the fan will continue running until the heat sink is cooled down accordingly again.

2.2.5.11 Emergency operation In case of voltage failure the frequency inverter can be used for emergency operation.

Conditions:

• 230 V AC at control voltage input (X1 / 2,3)

DC voltage or single-phase AC voltage power supply at terminals X1.11 and 13 (or L1 and L3) (see chapter 9.4.3Emergency operation, page 9-9). Emergency operation is signalled to MFC 20 through input X1.11a (PROGANA/default<emergency current 220V>). (Input X1.9b (PROGIN) to be used if input is required for analog load weighing) (see chapter 5.4.1 Variable parameters, page 5-17, P 48: Input Progana and P 49: Input Progin

2.4 System pertubation, EMC measures

2.4.1 Generals

To minimize system perturbation (radio interference or harmonics), the following additional external modules are available. Line filter and line chokes (see chapter 2.5.2 External modules, page 2-25).

Inverters have to be connected with these additional external modules as shown in the connection diagram. (See chapter 9.4 Connection diagrams, page 9-7).

12.8.2004 MFC 20_21_ENG / Version 01/04 2-17




2.4.2 Mounting instructions

The following measures will have to be taken for compliance with the relevant standards:

• Frequency inverter, line filter and line choke must be mounted on a zinced installation plate

• Run contactors, line filter and frequency inverter to be arranged in the control cabinet in accordance with the mounting instructions below.

• Lines between run contactors, line choke and line filter and frequency inverter input must be twisted or screened. These lines must be run separately from the remaining lines.

• Short and twisted connecting lines between frequency inverter and run contactors must be used in case the run contactors are between frequency inverter and motor.

• Screening of motor lines (14) and PTC thermistor lines (12). Cable screens to be contacted with the zinc-plated mounting plate and the motor casing on both sides to a large surface and electrically conducting in the vicinity of the frequency inverter (use EMC compliant cable clips or screwed conduits). The distance between screened motor cable and all other cables or lines shall be at least 0.2 m.

• If the delivered incremental encoder is used the encoder cable is already properly screened (i.e. conductor and encoder box screen placed over a large surface). Please note in case other encoders are used.

• Use EMC compliant connection between housing of the brake resistor and zinc-plated mounting plate. This can readily be achieved by screw connecting braking resistor housing and inverter cabinet through a large-surface electrically conducting connection. In this case, a non-screened connecting cable (13) can be used between inverter and brake resistor; the wires of this cable should be twisted however.

• The connection between brake resistor and frequency inverter must be in the form of a screened line (13) whose screen must be contacted with the respective reference potential (housing of the brake resistor or frequency inverter) on both sides, over a large surface and electrically conducting should direct installation on the control cabinet not be possible.

• The connecting line between elevator control and frequency inverter should be screened. The line screen must be earthed on the control side over a large surface. The need for a screened line can be dispensed with, if short connections are used. The cables must be twisted in this case, however.

The user is responsible for observing the EMC rules. Mounting instructions to be followed.

2.4.3 Line choke

The due installation of the line choke (in connection with the integrated DC reactor) produces the following advantages for the drive:

• Approximation of the current to sine-wave form

• Reduced harmonics of line current

• Limitation of commutation notches of line voltage to permissible values.

• Limitation of starting of inrush current of subsequently connected line filter

Proper mounting of the line filters will reduce radio interference to a permissible extent.

2.4.4 Line filter

Proper mounting of the line filters will reduce radio interference to a permissible extent.

The „Product family standard for elevators, escalators and passenger conveyors“ EN 12015 (emission) and EN 12016 (immunity) are complied with.

30 A and 36 A line filters with switches are provided for use of the frequency inverters in lines with residual-current operated devices (e.g. 30 mA in building site main cabinet). The leakage current of the filter with switch turned to "0" can be reduced, if necessary.

The switch shall be closed during normal operation (turned to “1”), to be able to achieve optimal EMC effect.

2.4.5 Installation of other cables

Cables (e.g. for motor brake) not belonging to the inverter must be run separately from motor cable, PTC thermistor cable and encoder cable for reasons of electromagnetic compatibility (EMC). It is also not permissible to run these cables through the motor terminal box.

Operating instructions - Safety instructions

4 Operating instructions

4.1 Safety instructions

A) Qualified staff

Work on the frequency inverter MFC 20 shall only be performed by trained persons.

These persons have to observe the relevant accident prevention rules (e.g. VBG 4) and they must be aware of the hazards inherent in electric current.

B) Working on frequency inverter

The following measures will have to be taken when work is performed on frequency inverters (except setting work on the control panel) or motor:

• Isolate from supply

• Save before restarting

• Verify isolation from supply

C) Verification of isolation from supply

Attention is drawn to the fact that electric energy may still be present in the device after power voltage is switched off (capacitor charge).

This particularly applies to defective devices.

Therefore, it is necessary to check for residual voltage prior to starting work on a frequency inverter.

A suitable multi-function instrument (min. 800 VDC) can be used for testing the link voltage for residual voltage on terminal strip X1, terminals 22 and 23.

Set measuring instrument to DC voltage range !

Work on the device open and with link voltage applied (approx. 700 VDC) to be performed only in exceptional cases and exercising the utmost care.

It is important to be aware that the link voltage has a fixed potential reference to the line voltage and the protective conductor.

12.8.2004 MFC 20_21_ENG / Version 01/04 4-3



Operating instructions - Operating instructions

4.2 Operating instructions

Frequency inverters incorporate components, which involve electrostatic hazards. Prior to performing any service work (i.e. replacing of boards), the service personnel must get rid of static charges by touching an earthed metallic surface.

• Incorrect assignment of inverter to motor may cause damage to inverter or motor.

• Frequent cyclical turning on and off the inverter may result in overloading of the internal load resistors. This can be avoided by reasonable breaks.

4.3 Points to be observed prior to initial powering on

• Check wiring to inverter and motor (including incremental encoder)

• Check EMC-compliant earthing of cable screens

• Check all component for correct protective earthing (frequency inverter, motor, housing and brake resistor)

• Check line voltage

• See to it that brake is in proper service condition and correctly adjusted

• Load car with 50 % load, if necessary (load compensation)

4-4 MFC 20_21_ENG / Version 01/04 12.8.2004



Operating instructions - Checking the visual displays in the event of errors

4.4 Checking the visual displays in the event of errors

Should the drive not function properly, the following functions can be checked on light-emitting diodes on computer board TMI (see chapter 4.8.1 LED and measuring points on computer board TMII, page 4-8) after removing the front cover (see Fig. 2-1: Frequency inverter MFC 2021, page 2-1).

The following light-emitting diodes must light with the device ready to operate:

H 40 (yellow) TI ...................... computer ok

H 7 (red) + 5 V ................. supply voltage + 5 V present

H 1 (red) BE ..................... no error, frequency inverter ready to operate

In addition during run:

H 99 (red) IF ...................... pulse enable

The light-emitting diodes can be identified from the computer mounting print of computer board TMI.

4.5 Input of elevator-specific values

The lift-specific values must be entered based on the LCD display and the keypad on module TPT (see chapter 5 Parameter entry, page 5-11):

• Motor type P 40

• Encoder pulse number P 96

• Acceleration change (jerk) P 19 [m/s³]

• Acceleration P 20 [m/s²]

• Levelling speed vo P 23 [m/s]

• Inspection speed vi P 24 [m/s]

• Rated speed vn P 25 [m/s]

• Intermediate speed v2 P 26 [m/s]

• 2. Intermediate speed vn2 P27 [m/s]

• Emergency operation v3 P 28 [m/s]





12.8.2004 MFC 20_21_ENG / Version 01/04 4-5



Operating instructions - Testing the drive for correct functioning

4.6 Testing the drive for correct functioning

Specify inspection operation speed vi in UP or DOWN direction.

Drive must move in the corresponding direction at desired inspection operation speed.

Should the drive move at proper speed but in the wrong direction, invert direction with parameter P 3 "control direction ".

If the drive is running irregularly or not at correct speed, invert control direction with parameter P 4 "control direction".

If inspection operation speed cannot be reached despite the change of control direction, check whether the incremental encoder is plugged in correctly and/or the encoder pulse number is correct (see chapter 5.4.2 P 105: Encoder pulse number , page 5-32).

4.7 Drive optimization

A) Speed controller

Parameter P5 „speed controller P gain“ 8 (default value 8) and P6 „speed controller I gain“ (default value 50 ms) are available for optimization of the actual-value running characteristic speed.

For optimization, proceed step by step.

Set „I gain“ fully to “0“, if required, and change „P gain“ to such an extent that the drive will run without a tendency to oscillate.

It must be noted that, dependent on the load direction involved, a lasting control deviation in the actual speed develops on the setting with „I gain 0“, i.e. the drive cannot accelerate in load direction under certain circumstances or it will even drive into the wrong direction.

The “P gain” should have a safety clearance to the tendency to oscillate mentioned above (smaller by a factor of approx. 2).

For normal operation, set an „I gain“ unequal „0“ again.

Experience has shown that the specified default values (P = 8 and I = 50 ms) lead to satisfactory running performance.

A recorder can be connected to MP 42A or MP 43A board TMI for assessment of the running characteristic. MP 26 or the inverter housing is the common reference point.

The measurement signals available at these display outputs area selected through parameter P10 or P11

Example:

The actual speed value with sign will be displayed at MP 42A with value "0" in P10 (see chapter 5 Parameter entry, page 5-11).

4-6 MFC 20_21_ENG / Version 01/04 12.8.2004



Operating instructions - Drive optimization

B) Run at rated speed

For optimization of rated speed run, acceleration and acceleration change (jerk) can be changed with parameters P19 and P20.

In so doing, see to it that a minimum jerk (see chapter 4.8.2 Diagram for determining the minimum jerk, page 4-9) must be set in line with the selected acceleration; if not, no range of constant acceleration will exist.

It must be noted that the floor-to-floor distance is greater than the sum from acceleration and deceleration distance from rated speed (see diagram). (see chapter.4.8.3 Diagram for determining the minimum floor-to-floor distances, page 4-10).

Rated speed will thus be reached whenever floor-to-floor runs are made.

C) Short run

A short run is present, if the floor-to-floor distance is less than the sum from acceleration and deceleration distance from rated speed, but greater than the deceleration distance from rated speed.

Rated speed will not be reached in floor-to-floor runs.

How to proceed for activation of short run see chapter 6 Short run device, page 6-1).

D) Load specification

Should the car depart after disengaging the brake, this can be reduced by entry of a starting torque (see chapter 5.1 General variable parameters, page 5-11, P50 to P54).

(See chapter 5.1 General notes on variable parameters P50 to P54).

This starting torque can be entered optimally by using load-weighing device LMS 1.

In the absence of load-weighing device, starting can also be optimized for a specific load condition.

E) Acceleration precontrol

Should the drive tend to overshoot or undershoot, this can be optimized by activation of acceleration precontrol (see chapter 5.1 General variable parameters, page 5-11, P21 and P22).

Parameter entry - General

5 Parameter entry

5.1 General

The program permits the parameters of a defined storage area to be changed. The permissible range of each parameter will be checked whenever an entry is made and limited accordingly. A distinction is made between variable parameters (e.g. maximum speed, direction of rotation or control parameters) and display parameters for indicating various operating values (e.g. current speed, current reference value, etc.).

The following display will appear on starting the MFC 20 frequency inverter:

Lift Equip Vers: MFC V11.y

This display of the program number version will appear for 15 seconds only.

Program version number to be quoted for any inquiries made to the factory.

If one of the keys is operated during these 15 seconds, the display of the version number will be discontinued immediately and the selected function will be performed.

If you wait for 15 seconds, the first available parameter will be displayed.

P 0 reference value start delay500 ms

The turn-on duration of the display lighting is set to two hours after the key was pressed last.

When a key is operated for the first time after turning off the lighting, the lighting will be turned on again, but this does not have any effect on the parameter function.

12.8.2004 MFC 20_21_ENG / Version 01/04 5-11



Parameter entry - Operation

5.2 Operation

Parameter entry permits the following functions:

5.2.1 Display and change of parameters

Fig. 5-1: Display of parameters

The parameter number with a short description of the selected parameter is in the first line, the current value with its physical unit in the second line. A cursor appears below the parameter number.

The desired parameter number can now be selected with the keys “+“ and “-“. By advancing the cursor with the „cursor“ key, the selection can now proceed in steps of tens or hundreds.

P 5 P gain 8,0

By operating the "parameter" key, the cursor will go to the numeric value and a change of the numeric value will be possible.

P 5 P gain 8,1

5-12 MFC 20_21_ENG / Version 01/04 12.8.2004




A stroke is below the least significant digit of the numeric value. This stroke marks that digit which will be changed by -1 by operating the “+“ key or by “-“. This marking will be shifted to the left by one position whenever the “cursor“ key is operated. This permits a quick change of the parameter throughout a wide range.

If the “+“ or “-“ key is held depressed for longer than two seconds, the parameter value will be changed by +1 or –1 at intervals of 0.25 seconds.

Some parameters, as e.g. P7 language, do not have a number as value, but a selection from a list.

P 7 Language → English

Here, too, the entry can be changed by operating the ”+” and ”-” keys.

The change of the parameter value will not become effective until the change is acknowledged by pressing the "parameter" key!

5.2.2 Display parameters

The display parameters show operating parameters such as momentary speed of motor. Selection of desired parameter as described in chapter 5.2.1 Display and change of parameters, page 5-12.

P 100 Motor speed + 103,5 min-1

The displayed value - actual speed in this case - will be continually updated.

5.2.3 Save changed parameters to EPROM

Without saving data like this, parameter changes will be lost after powering off the MFC 20 device!

The following display will appear after pressing the ”save” key:

Values to be saved? (+) = yes , (-) = no

12.8.2004 MFC 20_21_ENG / Version 01/04 5-13




If the “save“ key has been pressed inadvertently, the saving operation can be stopped by pressing the “-“ key (No). All parameters will be saved to the EPROM by operating the “+“ key (Yes). The following information will be displayed while saving is in progress:

The following information will be displayed while saving is in progress:

Data being saved ... Please wait ...

Never cut off the control voltage while saving is in progress. If this happens, check all parameters and correct them, if required.

5.2.4 All Parameters as factory-set

This function permits the original values of all parameters to be restored at any time. Pressing the „parameter“ key and simultaneously operating the “save“ key will cause the following inquiry to appear on the display:

Original values to be loaded ?(+) = yes , (-) = no

If the function was started inadvertently, the process can be discontinued by operating the “-“ key (No). If the “+“ (Yes) key is pressed, all parameters will be set to the factory-set values.

Attention:

These values preprogrammed at the factory are not yet saved, however. This means that the old values will be effective after powering the MFC 20 frequency inverter off and on again, unless saving was effected before (5.2.3 Save changed parameters to EPROM, page 5-13).

As soon as all parameters have assumed their original state, the following display will appear :

! Original values have not yet been saved !

5.2.5 Individual parameters as factory-set

If a parameter is to be set to its factory-set value, the parameter will have to be displayed as described in chapter 5.2.1 Display and change of parameters, page 5-12. If keys “+“ and “-“ are pressed simultaneously after operating the „parameter“ key (for changing its value), the factory-set values will be displayed. No other parameters will be changed.

Parameter entry - Error stack

5.3 Error stack

Error messages are stored in the EPROM. The entries can be visualized on the display.

5.3.1 Display error stack

For this purpose, key “-“ will have to be pressed with parameter 0 during parameter selection (see chapter 5.2.1 Display and change of parameters, page 5-12). The error then displayed is that which occured last.

Parameter entry - Parameters

5.4 Parameters

Parameters are divided into:

Variable parameters (see chapter 5.4.1 Variable parameters, page 5-17), which can alter the performance of the device.

Display parameters (see chapter 5.4.2 Display parameters, page 5-31) showing different operating states.

The available parameters depend on the software version used.

5.4.1 Variable parameters

P 0: Reference value start delay tSTS

The delay time between activation of the brake and enabling of the drive can be set in elevators without brake acknowledgement.

The reference value will not be started until the brake is disengaged. Values between 50 and 5000 ms can be set. The typical value is between 300 ms and 800 ms.

This value must be set to 5000 ms in elevators with brake acknowledgement. This means that the reference value start depends on the brake acknowledgement.

P 1: Brake application time (brake off time) tBE

Setting of the delay time between electrical disengagement of brake by EBS and mechanical “application“ of the brake. After expiry of this period of time, electrical disconnection (controller disable) of the frequency inverter will follow. Values between 50 and 5000 ms can be set.

P 3: Direction of rotation The motor's direction of rotation can be changed through this parameter. The parameter can be set to "not inverted" or "inverted" only.

P 3 Direction of rotation → not inverted

A change of this parameter brings about an immediate change of the direction of rotation.

12.8.2004 MFC 20_21_ENG / Version 01/04 5-17




P 4: Control direction

a) Asynchronous motor

The fact that the polarities of reference speed and actual speed values are in a correct relation to each other is of importance to the speed controller.

If this is not the case, the motor will rotate irregularly at low speed.

The control direction can be reversed through parameter P 4. The parameter can be set to 'not inverted' or 'inverted' only. A change of this parameter has the same effect as a reversal of two phases of the motor line.

b) Synchronous motor

This parameter is not available for MFC 21 (synchronous motors).

The motor connections U, V, W of synchronous motors must be connected exactly to prevent wrong assignment to encoder and magnet positions (poles), i.e. the control direction cannot be changed by interchanging two phases.

P 5: Speed controller - P gain

This is where the speed controller response can be set (setting values 0 .. 64,6)

P 6: Speed controller - I gain

Same as P5, but for the I component (setting values 0 ... 9999).

The smallest effective value is 4 ms.

If the I component is to be deactivated, 0 ms will have to be entered.

P 7: Selection of language

This is where the language can be selected. Language selection is in plain text.

P 7 Language → English

P8: RS 485 Mode

This is where a DCP or LS2 interface can be preset (default off).

A separate description of the DCP mode is available, on request.

P 13 ... P 17:

Parameters P 13 to P 16 can be used for computing the ratio between motor speed and car speed and, thus, the maximum motor speed required for reaching the nominal speed, which will be referred to as rated speed below.

These parameters have a direct effect on the rated speed computed (P 17) and therefore on the speed of the lift.

P 13: Gear ratio

When a geared drive is used, the ratio of the gear can be set here.

The ratio of gearless drives is 1.0. The ratio of gears is often stated as a relation (e.g. 50:2). However, the entry into P13 must be in decimal notation (50:2 25,0).

P 14: Traction sheave diameter

This parameter can be used for setting the drive's traction sheave diameter in mm.

P 15: Suspension

The number of suspensions has a direct effect on the ratio (see gear ratio). The ratio is always indicated as whole number.

P 17: Computer maximum speed n rated

The required maximum speed of the motor is automatically computed from the values of parameters P 13 to P 16 and then displayed.

P 18: Operating point for N=0

P 19: Acceleration change (jerk)

Set desired acceleration change (jerk) in [m/s³].

P 20: Acceleration

Set desired acceleration / deceleration in [m/s²].

P 21: Acceleration precontrol ON/OFF

Should the drive tend to overshoot or undershoot, the running performance can be improved by activating the acceleration precontrol.

This particularly applies to gearless drives.

P 22: Acceleration precontrol value

For assessment of the correct setting of acceleration precontrol, the actual speed value (P10 to “0”) should be measured at measuring point 42A and the controller output (P 11 to “7”) should be measured at point 43A.

P 21 = "OFF" (precontrol off)

If no recorder is available, these measurements can also be made with a digital voltmeter.

Parameter for speed setting

• One of the five speeds is selected via inputs at connector X1 on board TIC.

• When vi or v0 and one of the remaining main speeds are selected at the same time, the

order is as follows:

inspection speed vi has priority, i.e. as soon as vi is selected, all other speeds will be ignored.

levelling speed v0 can always be selected and will not be effective until all the other speeds

are inactive.

• After selecting a speed value, a nominal/actual value comparison will be carried out ("tolerance band monitoring"). Excessive variance causes emergency stop to be activated.

• Emergency stop at inspection speed Vi or emergency operation speed V3 is only be activated if the nominal value exceeds 130 % of the respective actual value.

• Acceleration and jerk values are the same for all run characteristic sections (acceleration, deceleration, lower and upper roundings).

• The stopping distance from levelling speed end v0 to "Electrically activated stop" (zero speed) is only dependent on value v0 and the set jerk of the run characteristics. This stopping distance cannot be parameterized separately. Example: v0 = 0,1 m/s, jerk = 0,8 m/s³ -> stopping distance: 35 mm.

• Short run function only works at rated speed vn .

• Normal levelling speed v0 is 0,1 m/s; if value v0 is lower the "levelling time" will increase substantially.

Improved running performance for asynchronous motor using load-weighing device LMS 1

Entering a starting torque can reduce reverse rotation of the car on disengagement of the brake.

This specification is made either with the help of a load-weighing device LMS 1or it can be entered for a single specific load condition, if no load-weighing device is available.

P 50: Load specification (OFF/ON)

Switch load control ON / OFF.

a) without load-weighing device LMS 1

This specification will then be optimal for one load state only.

If no load-weighing device is available, the load specification can be enabled/disabled with P 50 and a fixed value can be entered with P 54.

Observe that the values P51 and P52 must be unequal as internal computation is made by formula [(P 51 - P 52) x P 54].

P 51 = 0, P 52 = 45% (default value) is recommended.

b) with load-weighing device LMS 1

Load weighing through analog signal: set P 48 to <1> LMS +- 10 V (use input PROGANA)

Load weighing through frequency signal: set P 49 to <1> load-weighing FM (use input PROGIN)

P 51: Current value/load-weighing

This is where the current loading state of the car is indicated in % of rated load.

(Approx. 45 % in the event of load compensation of car as standard).

This implies that the load-weighing device LMS 1 was correctly adjusted beforehand.

P 52: Value LMS 1/load compensation

In the event of load compensation, the loading state must be entered here. It can be determined experimentally as follows:

1. Establish load compensation

(car shall not start spinning with the brake disengaged)

2. Read current value of LMS 1 from P 51

3. Enter value into P 52

or enter any empirical value, e.g. 45 % means that the counterweight is 45 % of rated load.

12.8.2004 MFC 20_21_ENG / Version 01/04 5-27




P 53: Adopt load current

During a constant run with emergency electrical operation (e.g. empty UP or DOWN) the momentary load current will be displayed.

The load specification - gain - will be computed internally from this current value by operating the ”+” or ”- ” key during this run at constant speed.

The value in P 54 will be overwritten.

P 54: Load specification - gain

The value (with sign) of gain computed here will be specified through P 53. A fine adjustment, if necessary, can be made here.

Improved starting performance for synchronous motors using load controller

P 55: Control position controller gain (without load weighing)

Sensor for signalling load weighing is no longer necessary, which improves the starting performance of synchronous gearless drives. Load weighing is effected through the high-resolution load signal from the sine/cosine encoder.

A position controller replaces the existing precontrol signal from the load sensor. As soon as the pulses are enabled and the brake opened, the car is hold in its momentary position through the load controller. Intervention gain to be set through parameter P55. The position controller is disabled at the running characteristic start to permit control to be effected by the speed controller.

Preparation:

TMI board: EPROM version from V5.5b, FLASH program from F030701.

P 0 = 280 ms re-adjust reference value start delay

P 50 = OFF switch off load weighing

P 55 = 5 (start value) enable control of position controller gain

Setting:

When starting from upper-most landing downwards with the car empty, P 55 will be set to a value where reverse rotation of the car is avoided. Small values to be selected, preferably. Check selected setting during running performance in opposite run direction and readjust P 55 to avoid jerk. Values from P 55 = 0.1 to 25 to be selected.

Note:

Retrofitting of existing installations is possible. The method above does not replace use of overload sensor. "Occupied", "abuse" and "no load" conditions cannot be recognized.

P92: Discharge DC link

Prior to start working on the frequency inverter or motor connection it is necessary to discharge the DC link for reasons of safety (see chapter 1.2 General safety instructions, page 1-2 and chapter 2.2.2 Warnings, page 2-4)!

The DC link voltage in Volt is displayed by this parameter. The external brake resistor is controlled cyclically and the DC link capacitor discharged by pressing the “+“ or “-“ key at the same time. Pressing the P/W key at the same time can speed up discharging.

Discharge of DC link is only possible with signal “QSP“ = 0, i.e. the line contactor released and the brake resistor in perfect working condition. Power supply must be disconnected in case of installations, where the contactors are connected between motor and frequency inverter and not between mains and frequency inverter. However, the control voltage must be connected until DC link is discharged.

Short run device

6 Short run device

6.1 General

A short run is present, if the floor-to-floor distance is shorter than the sum from acceleration and deceleration distance for rated speed. Rated speed is not reached during such a run. To arrive in the landing, the car will have to move at levelling speed over a longer period of time.

The built-in short-run device recognizes this state and it extends the acceleration phase of the run automatically. The levelling time into the landing is thus the same as with run at rated speed, i.e. no creep or only short creep (operating delay or rope slip). (Fig. 6-1: Normal run).

The lift data must be set correctly, so that the short-run device will operate correctly.

These are:

• P13 Gear ratio

• P14 Traction sheave diameter

• P15 Suspension

• P19 Jerk

• P20 Acceleration

• P23 Speed v0

• P25 Speed vN

The deceleration distance vN will be computed from these parameters and indicated in

parameter P111. The deceleration distance will be measured for each normal run (v

N is reached) and displayed in P112. However, this measured distance will not be considered

in the short-run calculation.

Short run with "sharper rounding" (Fig. 6-3: "Short run with sharper rounding"). This is the case, if the deceleration point is reached during the top rounding of the acceleration phase. If deceleration with the set jerk is performed, the deceleration distance will be too large. The landing will be bypassed. To avoid this, the run will have a "sharper rounding" i.e. a greater jerk.

P39: Correction of short-run distance In the event of switching delay times of the control or rope slip, it may become necessary to correct the levelling distance in a short run. If higher figures are entered, the creep distance to the landing will become longer, if lower values are entered, the creep distance will become shorter. Values from –40.0 cm to +40.0 cm are possible.

Modernization

7 Modernization

7.1 General

Frequency inverter MFC 20 is also designed for use in modernization jobs at elevator installation with third-party motors (no ThyssenKrupp motor). Single-speed or pole-changing motors may be selected.

A vector control is used here, too.

Max. speed of 1.6 m/s is recommended.

The necessary information about modernization jobs is given in the following description.

7.2 Modernization by encoder mounted on motor shaft

The following applies:

• Operation of single-speed or pole-changing motors, frequency inverter and standard motors is possible.

• Motors should be of isolation class F; to reduce the wiring stress a frequency inverter output choke is used.

• Inertia is to be reduced to max. 1/3 of the original value.

• Devices MFC 20 - 32, - 48 and - 60 are to be used only.

• The encoder on the motor shaft is to be mounted centrally and stiff against torsion.

• The encoder must send push-pull TTL signals with 5 V supply voltage. (See chapter 2.3.3 Incremental encoder connection, page 2-13)

• Synchronous motors must be equipped with a sine/cosine encoder ("EnDat"). Connection assignment (See chapter 2.3.3 Incremental encoder connection, page 2-13)

• Min. floor-to-floor distance to be observed (see chapter 4.8.3 Diagram for determining the minimum floor-to-floor distances, page 4-10) (area A or B).

The braking resistor used depends on the type of installation (see chapter 2.5.2.4 External brake resistors, page 2-28).

7.2.2 Settings for motor adaptation

To adapt an unknown motor to the frequency inverter proceed accordingly, by iteration for example. Start with the name plate data. In so doing please note that these data may be incomplete or unequal to the rated working point of the frequency inverter in case of old lift motors as the ratio of maximum current to rated current was limited to special values. This normally results in an excessive no-load current of the frequency inverter. Also see table at the end of this chapter.

Release below parameters by selecting "third party motor" in P40.

a) Automatic current controller optimization (autotuning P 80) to be effected.

b) The values of P 65 („rotor time constant TR“) and P 66 („no-load current Id“) are calculated from parameters P 60 („rated frequency of motor“), P 61 („rated voltage of motor“), P 62 („rated speed of motor“), P 63 („rated current of motor“) and P 64 („motor cos (phi)“). As a rule, the values of P 65 are between 40 ms and 400 ms, and the values of P 66 between 6 Aeff and 30 Aeff (dependent on motor output).

If negative values are used for P 67 or P 68, the computed values of P 65 and P 66 will continuously be adopted. These are the default values.

d) These presettings permit an approximate basic setting of the motor. Load compensation is required to ensure that no-load current is present only (load current < 5% of max. current) if the lift runs at constant speed (electric recall operation, for example). Now initiate run at rated speed. A band error may arise during acceleration; disconnect the band monitoring, if necessary, or set slower acceleration value. Now observe the actual motor voltage in parameter P 76. This value should be between 270 and 300 V with the lift running at rated speed. Decrease motor voltage through P 68 (no-load current Id) (the arising motor voltage based on the no-load current from the name plate data is too high, normally). The motor voltage in P 76 should be approx. between 270 to 300 V both for UP and DOWN direction.

Increase or decrease the rotor time constant TR in P 67 if the torque required for acceleration phase is insufficient. This value can be changed step by step by 25 %.

Modernization - Modernization by encoder mounted on motor shaft

e) Now move the lift with empty car; this means that motor-driven run under no load shall be performed in DOWN direction and a brake test during run in UP direction. The motor voltage shall increase by the value of the motor slip with the lift running in DOWN direction, i.e. approx. 30 V to 50 V; decrease of the motor voltage shall be less in UP direction (approx. 10 V to 30 V). If this is not the case, change the value of the rotor time constant in P 67 step by step by 25% each. Perform setting when the motor runs at operating temperature (and not with extremely cold or hot motor).

f) Check setting of speed controller once again. Set I-gain of controller to 0 ms and increase P-gain until the motor vibrates or hums. Now reduce P-gain to half value. Select I-gain approx. between 10 ms and 100 ms depending on overshooting of running characteristic. Pre-controlling of the speed controller through acceleration precontrol (P 21 und P 22) improves running performance. Check running performance with the car running at no-load, half load and full load.

DCP Interface

8 DCP Interface

8.1 Preface

DCP03 and DCP04 is a serial data bus protocol to connect the inverter to the elevator control. RS485 interface (connection X90) is used here; Kollmorgen has specified the protocol. For further details on product specification please contact Kollmorgen Steuerungstechnik GmbH Köln. Email: [email protected] DCP04 is adapted to the inverter and thus designed for max. speed of 6 m/s. For use of higher speeds, please contact the manufacturer.

8.1.1 Installation

Connect RS485 inverter interface with control. Contactor X90 is to be used here. The corresponding assignment is: 1=signal B, 2=signal A, 3= earth reference RS485. A twisted-conductor, shielded line is recommended. Connect the control cabinet of the control over a large surface to the inverter housing by means of a copper band, for example. It is recommended to place the DCP connection shield on both sides of the box. A shield placed on the inverter side of the box only may be advantageous for major distances between inverter and control.

Run contactors attracted must be signalled to the inverter in case of MFC20.devices. Unfortunately contactors acknowledge has not been provided for DCP message interchange. Wiring is the same as for conventional controls. (Input QSP1 terminal X1-10b)

The MFC30.devices have integrated run contactors and contactor acknowledges. The relay output ("contactor control", terminal X1-4a, 5a) has been provided to comply with the requirements for monitoring as set out in EN81.

8.1.2 Speed assignment and designations

9 speeds are possible. DCP03 uses 5 speeds to be selected through bit G0, G1, G4, …G7 3 speeds thereof are maximum limits for DCP04. To be selected through bit G7, G6 or G1. The inverter may slow down under certain conditions. Attention: special runs in accordance with DCP03 specification are possible under DCP4 operation; this means that the values for the remaining speeds (bit G5, G4, G0) must be entered, too.

The elevator component manufacturers use different speed designations meanwhile, which entail the danger of confusion and mixup.

DCP Interface

P72 : permits to travel a specific run distance at constant speed. When shorter runs are performed at lower speeds, energy consumption and wear will be slightly reduced. Run time will slightly increase in return. Max. 1/3 of the run distance is performed at constant speed irrespective of the distance entered. This setting does not have any effect on longer runs where sections to be run at constant speed are standard.

P73: elevators approaching the landing may be forced to travel a defined distance at creeping speed before arriving at the landing. If the exact ratio is unknown when setting the elevator into service it is recommended to enter a great value here. The deceleration distance from creeping speed V0 to zero is already implied here. Should the elevator tend to overrun the destination landing, a higher value must be entered here.

P74 see 8.1.5 Stopping accuracy under DCP04 operation

P75 stop position controller gain While the elevator is running, the run characteristics is computed from the parameters set for speed, acceleration and jerk and transmitted to the speed controller. Computation is continued up to last few mm before reaching the stop. The reference speed control values are determined from stopping accuracy distance. Actual stop is almost equal to position pre-set by the DCP control. Controller gain is set through P75. Increase the value set for creep distance (P73) to 50....100mm, for example, if there is an uncomfortable jerk during stopping. Then re-set P75 to ensure smooth and comfortable stopping. As soon as the value in P75 leads to proper stopping accuracy and smooth stopping, P73 can be re-set P73 to smaller value.

8.1.4 Safety function TIMEOUT control

If the inverter fails to receive a valid DCP message for more than 150ms while the elevator is in operation, emergency stop will be effected. "DCP error" and the number of DCP messages with wrong checksum received since switching on are displayed in the event-error stack of the inverter. The corresponding service hour counter status for each stack entry is displayed too.

Emergency stop means: disable pulses, open run contactors and close mechanical brake.

8.1.5 Stopping accuracy under DCP04 operation

Gear ratio, suspension and traction sheave diameter for DCP04 operation are to be entered with utmost care. Inaccurately entered traction sheave diameters can cause unsatisfactory stopping accuracy. When the elevator is running, the values for run speed at control display and those of parameter P101 "actual speed" at inverter display must be the same. Should exact traction sheave diameter be unknown, a mathematically computed average value is displayed in P74 "traction sheave computed" of inverter after each run. This value is computed from the distance signalled from control and the values signalled from drive encoder. However rope slip and rounding errors will lead to an inaccurate result. After performing a couple of runs to several landings a significant result will be achieved. Zero may be displayed in P74 if runs to or from the lower-most landing are made. If so, perform runs between two other landings and read P74. Enter this value in P14 "traction sheave" if the same or almost the same value is read repeatedly. The drive always tends to run too fast or overrun if the value entered in P14 "traction sheave" is too small. If the value entered is too great, the drive tends to excessive creep distance at excessively slow speed.
