Note: Use twisted-shielded, twisted-pair or shielded-lead wires for the control signal wiring. It isrecommended to run all signal wiring in a separate steel conduit. The shield wire shouldonly be connected at the drive. Do not connect shield wire on both ends.

Wire Gauge: 12-14 AWG

Wire Type: Copper Only

Torque: 4 kg-cm



CH 2-8 Wiring Notes:

1. !! CAUTION: Do not connect the AC input to any of the U, V, W terminals, as it will damage

the AC drive.

2. !! WARNING: Ensure all screws are tightened to the proper torque rating.

3. During installation, follow all local electrical, construction, and safety codes for the country the

drive is to be installed in.

4. Ensure that the appropriate protective devices (circuit breaker or fuses) are connected between

the power supply and AC drive.

5. Make sure that the leads are connected correctly and the AC drive is properly grounded.

(Ground resistance should not exceed 100. For 460V-class AC drive, the ground resistance

should not exceed 10.)

6. Use ground leads that comply with AWG/MCM standards and keep them as short as possible.

7. Multiple VFD-M units can be installed in one location. All the units should be grounded directly

to a common ground terminal. The VFD-M ground terminals may also be connected in parallel,

as shown in the figure below. Ensure there are no ground loops.

Forwardrunning

8. When the AC drive output terminals U, V, and W are connected to the motor terminals U, V,

and W, respectively, the motor will rotate counterclockwise (as viewed from the shaft ends of

the motor) when a forward operation command is received. To reverse the direction of motor

rotation, switch any of the two motor leads.

9. Make sure that the power source is capable of supplying the correct voltage and requiredcurrent to the AC drive.



10. Do not attach or remove wiring when power is applied to the AC drive.

11. Do not monitor the signals on the circuit board while the AC drive is in operation.

12. For the single-phase applications, the AC input line can be connected to any two of the three

input terminals R, S, T. Note: This drive is not intended for the use with single-phase

motors.

13. Route the wires of Power Terminals and Control Terminals separately, or 90°angle to eachother.

14. If a filter is required for reducing EMI (Electro Magnetic Interference), install it as close aspossible to AC drive. EMI can also be reduced by lowering the Carrier Frequency.

15. If the AC drive is installed in the place where load reactor is needed, install the filter close toU.V.W. side of AC drive. Do not use a Capacitor or L-C Filter (Inductance-Capacitance) or R-CFilter (Resistance-Capacitance).

16. When using a GFCI (Ground Fault Circuit Interrupt), select current sensor with not less than

200mA, with not less than 0.1-second detection to avoid nuisance tripping



CH 2-9 Motor Operation Precautions:

1. When using the AC drive to operate a standard 3-phase induction motor, notice that the energyloss is greater than an inverter duty motor.

2. While using the standard induction motor at low speed, due to the cooling fan running at lowspeed, the temperature of the motor may rise, so do not operate the motor at low speed for along period of time.

3. When the standard motor operates at low speed, the motor output torque will decrease, pleasedecrease the load during the operation.

4. If 100% output torque were desired at low speed operation, it may be necessary to use aspecial motor that can handle this load (inverter duty).

Note: 1. DC Braking during Start-up is used for loads that may move before AC drive starts,

such as fans and pumps. These loads may also be moving in the wrong direction.

Under such circumstances, DC Braking can be executed to hold the load in

position before applying a forward motion.

2. DC Braking during stopping is used to decrease stopping time and also to hold a

stopped load in position. For high inertial loads, a dynamic braking resistor may

be needed for quick decelerations.

the AC drive will resume operation. If the Maximum Allowable Power Loss Time is

exceeded, the AC drive output is then turned off.

Pr.34 Base-Block Time for Speed Search Factory Setting: d0.5 Sec


& When a momentary power loss is detected, the AC drive turns off for a specified time

interval determined by Pr.34 before resuming operation. This time interval is called

Base-Block. This parameter should be set to a value where the residual output voltage

is nearly zero, before the drive resumes operation.

output terminal AFM.

The analog output voltage is directly proportional to the output frequency of the AC drive. With

the factory setting of 100%, the Maximum Output Frequency (Pr.03) of the AC drive

corresponds to +10VDC analog voltage output. (The actual voltage is about +10VDC, and can

be adjusted by Pr.44)

The analog output voltage is directly proportional to the output current of the AC drive. With

the factory setting of 100%, the 2.5 times rated current of the AC drive corresponds to +10

VDC analog voltage output. (The actual voltage is about +10 VDC, and can be adjusted by

Pr.44)

Note: Any type of voltmeter can be used. If the meter reads full scale at a voltage less than

10 volts, then Pr.44 should be set by the following formula:

Pr.44 = ((meter full scale voltage)/10)×100%

For Example: When using the meter with full scale of 5 volts, adjust Pr.44 to 50%

Chapter 5 Maintenance and Inspections

Modern AC drives are based on solid state electronics technology, preventive maintenance is

required to operate this AC drive in its optimal condition, and to ensure a long life. It is

recommended to perform a monthly check up of the AC drive by a qualified technician. Before

the check up, always turn off the AC Input Power to the unit. Wait at least 2 minutes after all

display lamps have gone out, and then confirm that the capacitors have fully discharged.

CH 5-1 Periodic Inspection:

Basic check up items to detect if there were any abnormality during the operation.

1. Whether the motors are operating as expected.

2. Whether the installation environment is abnormal.

3. Whether the cooling system is operating as expected.

4. Whether any irregular vibration or sound occurred during the operation.

5. Whether the motors are overheated during the operation.

6. Always check the input voltage of the AC drive with Voltmeter.

CH 5-2 Periodic Maintenance

It is necessary to stop the motor operation during the check up.

1. Tighten and reinforce the screws of the AC drive if necessary, cause it may loose due to the

vibration or changing of temperatures.

2. Whether the conductors or insulators were corroded and damaged.

3. Check the resistance of the insulation with Megaohmeter.

4. Often check and change the capacitors and relays.

5. If use of the AC drive is discontinued for a long period of time, turn the power on at least

once every two years and confirm that it still functions properly. To confirm functionality,

disconnect the motor and energize the AC drive for 5 hours or more before attempting to run

a motor with it.

6. Clean off any dust and dirt with a vacuum cleaner. Place special emphasis on cleaning the

ventilation ports and PCBs. Always keep these areas clean, as adherence of dust and dirt

can cause unforeseen failures.

discretion, with the same or a functionally equivalent product, provided the original purchaser (A)

returns the failed product, and (B) provides proof of original date of purchase. This warranty

does not apply, in the judgment of Delta, to damage caused during shipment, handling, storage,

or accidental misuse. The original purchaser of the product must obtain a Return Material

Authorization (RMA) number from Delta prior to returning any defective product. (When

purchased through an Authorized Distributor, the Distributor should supply an RMA number to

their customer.)

The maximum liability of this warranty is limited to the purchase price of the product. In no

event, regardless of cause, shall delta be liable (a) for penalties or penalty clauses of any

description, or (b) for certification not otherwise specifically provided herein and/or

indemnification of purchaser or others for costs, damages or expenses, each arising out of or

related to the product or services of any order or (c) for any damages resulting from loss of

profits, use of products or for any incidental indirect or consequential damages, even if advised

of the possibility of such damages.
