VFD-V Series

Preface

Thank you for choosing DELTA’s high-performance VFD-V Series. VFD-V Series

are manufactured by adopting high-quality components, material and incorporating the

latest microprocessor technology available.

 Getting Started

This manual will be helpful in the installation, parameter setting, troubleshooting, and daily

maintenance of the AC motor drives. To guarantee safe operation of the equipment, read

the following safety guidelines before connecting power to the AC drives. Keep this

operating manual handy and distribute to all users for reference.

WARNING

Always read this manual thoroughly before using VFD-V series AC Motor Drives.

DANGER! AC input power must be disconnected before any maintenance. Do not

connect or disconnect wires and connectors while power is applied to the circuit. Maintenance must be performed by qualified technicians.

CAUTION! There are highly sensitive MOS components on the printed circuit boards.

These components are especially sensitive to static electricity. To avoid damage to these components, do not touch these components or the circuit boards with metal objects or your bare hands.

DANGER! A charge may still remain in the DC-link capacitor with hazardous voltages

even if the power has been turned off. To avoid personal injury, please ensure that power has turned off before operating AC drive and wait ten minutes for capacitors to discharge to safe voltage levels.

CAUTION! Ground the VFD-V using the ground terminal. The grounding method must

comply with the laws of the country where the AC drive is to be installed. Refer to Basic Wiring Diagram.

DANGER! The AC drive may be destroyed beyond repair if incorrect cables are

connected to the input/output terminals. Never connect the AC drive output terminals U/T1, V/T2, and W/T3 directly to the AC main circuit power supply.

CAUTION! The final enclosures of the AC drive must comply with EN50178. (Live parts

shall be arranged in enclosures or located behind barriers that meet at least the requirements of the Protective Type IP20. The top surface of the enclosures or barrier that is easily accessible shall meet at least the requirements of the Protective Type IP40). (VFD-V series corresponds with this regulation.)

CAUTION! Heat sink may heat up over 70oC (158oF), during the operation. Do not

touch the heat sink.

2.2 Installation

CAUTION

The control, power supply and motor leads must be laid separately. They must not be fed through the same cable conduit / trunking.

High voltage insulation test equipment must not be used on cables connected to the drive.

Improper installation of the AC drive will greatly reduce its life. Be sure to observe the

following precautions when selecting a mounting location.

Failure to observe these precautions may void the warranty!

 Do not mount the AC drive near heat-radiating elements or in direct sunlight.

 Do not install the AC drive in a place subjected to high temperature, high humidity,

excessive vibration, corrosive gases or liquids, or airborne dust or metallic particles.

 Mount the AC drive vertically and do not restrict the air flow to the heat sink fins.

The AC drive generates heat. Allow sufficient space around the unit for heat dissipation.

3.6 Wiring Notice

1. There are corresponding ring terminals which will be included with each unit (15-30HP),

and please use the proper crimping tool by KST INC. P/N: KST-HDC38A for securing

the conductor.

2. When wiring up, and that the wiring route specifications are settled, please conduct the

wiring following the electrician regulations.

3. The connection between the three-phase AC input power and the main circuit terminal

R/L1, S/L2, T/L3 has to set up a none-fusing switch in between. The best is to series

connect with an electro-magnetic contactor (MC) so as to cut off the power supply at the

same time when the inverter protection function acts. (The two ends of the

electro-magnetic contactor should have the R-C Varistor).

4. There is no phase-order differentiation in the input power R/L1, S/L2, T/L3 and users

could connect with either one of use.

5. The ground terminal E is grounded with the third-type grounding method (with the

grounding impedance under 100Ω).

6. The grounding wire of the inverter could not be grounded at the same time with

machinery with grand current loading, like that of the electric soldering machine and of

the motor with grand horsepower; they have to be grounded individually.

7. The shorter the ground wire, the better it is.

8. When several inverters are grounded at the same time, be sure not to make it into a

ground circuit. Please refer to the following diagram:

FWD RUN

9. If the output terminals U/T1, V/T2 and W/T3 of the inverter are connecting relatively to

the U, V, and W terminals of the motor, the FWD indicator located on the digital control

panel of the inverter will be lit, and that means the inverter is running forward, and the

rotation direction of the motor will be shown as the right hand side diagram above; if the

REV indicator is lit, it means that the inverter is running in reverse direction, and the

rotation direction will be of the opposite direction compared with the above diagram. If

users are not sure of whether the connection between output terminals U/T1, V/T2 and

W/T3 of the inverter is of one-to-one connection with U, V, and W terminals of the motor,

simply swap either two wires among the U, V, and W terminals of the motor for

correction if the inverter is running forward while the motor is running at reverse

direction.

3-14

VFD-V Series

10. Be sure of the power voltage and the greatest current possible supplied.

11. When the “Digital Hand-held Programming Panel” is displayed, please do not

disconnect or dissemble any wiring.

12. No braking resistor is installed within the VFD-V inverter (selective purchasing item),

therefore, be sure to purchase and install the braking resistor if to be used on occasions

when the loading inertia is great or that it is of frequent start/stop.

13. Be sure not to connect the AC power with the terminals U/T1, V/T2 and W/T3 on the

power-generating side of the inverter.

14. Please tightly fasten the screws of the main circuit terminals so as to prevent sparks

generated due to the vibration and loosening of the screws.

15. Wiring of the main circuit and of the control circuit should be separated so as to prevent

erroneous actions. If the interlock connection is needed, please make it an

intersection of 90°.

16. If terminals U/T1, V/T2 and W/T3 on the power-generating side of the inverter is in need

of the noise wave-filter, it is then necessary to use the induction-type L-Varistor, but be

sure not to add in the phase-carrying capacitor or the L-C- and R-C-type wave filters.

17. Please use the separating wire as much as possible during control wiring, and be sure

not to expose the peeled-off separation net in front of the terminal to the external.

18. Please use the separating wire or tube as much as possible during power wiring, and

ground these two ends of the separating layer or tube to the ground.

19. If the installation site of the inverter is sensitive to interferences, please have the RFI

wave filters installed, and the nearer the inverter to the installation site, the better. In

addition, the lower the carrier wave frequency of, the less the interferences.

20. If the electric-leakage circuit breaker is installed in the inverter, it could serve as the

protection for the electric-leakage error, and as the prevention on the erroneous actions

of the electric-leakage circuit breaker; please select the sensor current above 200mA

with the action time of more than 0.1 second to have these actions accessible.
