DELTA VFD-F User Manual

VFD-F Series

Preface

Thank you for choosing DELTA’s high-performance VFD-F Series. VFD-F 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-F series AC Motor Drives.

DANGER!

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, do not remove the cover of the AC drive until all “DISPLAY LED” lights on the digital keypad are off. Please note that there are live components exposed within the AC drive. Do not touch these live parts.

CAUTION! Ground the VFD-F 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-F series corresponds with this regulation.)

CAUTION! The rated voltage for the AC motor drive must be ≤ 240V for 230V models (≤

480V for 460V models) and the mains supply current capacity must be ≤ 5000A RMS (≤10000A RMS for the ≥ 40hp (30kW) models)

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

the heat sink.

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

2.2 Installation

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.

3.5 Wiring Notes:

CAUTION: Do not connect the AC power to the U/T1, V/T2, W/T3 terminals, as it

PLEASE READ PRIOR TO INSTALLATION.

will damage the AC drive.

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 0.1Ω.)

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

possible.

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

directly to a common ground terminal. The VFD-F ground terminals may also be

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

Forward running

8. When the AC drive output terminals U/T1, V/T2, and W/T3 are connected to the motor

terminals U/T1, V/T2, and W/T3, 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 over any of the two motor leads.

9. Make sure that the power source is capable of supplying the correct voltage and

required current to the AC drive.

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

11. Do not inspect components unless inside “CHARGE” lamp is turned off.

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

3-16

VFD-F Series

13. For the single-phase rated AC drives, the AC power can be connected to any two of the

three input terminals R/L1, S/L2, T/L3. Note: This drive is not intended for the use

with single-phase motors.

14. Route the power and control wires separately, or at 90°angle to each other.

15. If a filter is required for reducing EMI (Electro Magnetic Interference), install it as close

as possible to AC drive. EMI can also be reduced by lowering the Carrier Frequency.

16. If the AC drive is installed in the place where a load reactor is needed, install the filter

close to U/T1, V/T2, W/T3, side of AC drive. Do not use a Capacitor or L-C Filter

(Inductance-Capacitance) or R-C Filter (Resistance-Capacitance), unless approved by

Delta.

17. When using a GFCI (Ground Fault Circuit Interrupt), select current sensor with sensitivity

of 200mA, and not less than 0.1-second detection to avoid nuisance tripping.

18. To improve the input power factor, to reduce harmonics and provide protection from AC

line disturbances (surges, switching spikes, short interruptions, etc.), AC line reactor

should be installed when the power supply capacity is 500kVA or more.

19. There are highly sensitive MOS components on the printed circuit boards. These

components are especially sensitive to static electricity. To prevent damage to these

components, do not touch these components or the circuit boards with metal objects or

your bare hands.

3.6 Motor Operation Precautions

1. When using the AC drive to operate a standard 3-phase induction motor, notice that the

energy loss is greater than for an inverter duty motor.

2. Avoid running a standard induction motor at low speed. Under these conditions, the

motor temperature may rise above the motor rating due to limited airflow produced by

the motor’s fan.

3. When the standard motor operates at low speed, the output load must be decreased.

4. If 100% output torque is desired at low speed, it may be necessary to use a special

“inverter-duty” rated motor.
