Preface

Thank you for choosing DELTA’s high-performance VFD-B Series. The VFD-B Series is
manufactured with high-quality components and materials and incorporates the latest microprocessor
technology available.

 Getting Started

This quick start will be helpful in the installation and parameter setting of the AC motor drives. To
guarantee safe operation of the equipment, read the following safety guidelines before
connecting power to the AC motor drives. For detail information, refer to the VFD-B User Manual
on the CD supplied with the drive.

DANGER!

1. AC input power must be disconnected before any wiring to the AC motor drive is made.

2. A charge may still remain in the DC-link capacitors with hazardous voltages, even if the power has
been turned off. To prevent personal injury, please ensure that power has been turned off before
opening the AC motor drive and wait ten minutes for the capacitors to discharge to safe voltage levels.

3. Never reassemble internal components or wiring.

4. The AC motor drive may be destroyed beyond repair if incorrect cables are connected to the
input/output terminals. Never connect the AC motor drive output terminals U/T1, V/T2, and W/T3
directly to the AC mains circuit power supply.

5. Ground the VFD-B using the ground terminal. The grounding method must comply with the laws of the
country where the AC motor drive is to be installed. Refer to the Basic Wiring Diagram.

6. VFD-B series is used only to control variable speed of 3-phase induction motors, NOT for 1-phase
motors or other purpose.

7. VFD-B series shall NOT be used for life support equipment or any life safety situation.

WARNING!

1. DO NOT use Hi-pot test for internal components. The semi-conductor used in the AC motor drive is
easily damaged by high-pressure.

2. 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. Only quality person is allowed to install, wire and maintain AC motor drive.

CAUTION!

1. Some parameter settings will cause the motor to run immediately after applying power.

2. DO NOT install the AC motor drive in a place subjected to high temperature, direct sunlight, high

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

3. Only use AC motor drives within specification. Failure to comply may result in fire, explosion or electric

shock.

4. To prevent personal injury, please keep children and unqualified people away from the equipment.

5. When the motor cable between the AC motor drive and motor is too long, the layer insulation of the

motor may be damaged. Please use a frequency inverter duty motor or add an AC output reactor to
prevent damage to the motor. Refer to appendix B Reactor for details.

6. The rated voltage for the AC motor drive must be ≤240V (≤480V for 460V models, ≤600V for 575V

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

Fault Codes

Fault

Name

Fault Descriptions Corrective Actions

Over current

Abnormal increase
in current.

IGBT protection

(Insulated Gate
Bipolar Transistor)

1. Check if motor power corresponds with the AC motor drive
output power.

2. Check the wiring connections to U, V, W for possible short
circuits.

3. Check the wiring connections between the AC motor drive
and motor for possible short circuits, also to ground.

4. Check for loose contacts between AC motor drive and motor.

5. Increase the Acceleration Time.

6. Check for possible excessive loading conditions at the
motor.

7. If there are still any abnormal conditions when operating the
AC motor drive after a short-circuit is removed and the other
points above are checked, it should be sent back to
manufacturer.

Over voltage

The DC bus
voltage has
exceeded its
maximum
allowable value.

1. Check if the input voltage falls within the rated AC motor
drive input voltage range.

2. Check for possible voltage transients.

3. DC-bus over-voltage may also be caused by motor
regeneration. Either increase the Decel. Time or add an
optional brake resistor (and brake unit).

4. Check whether the required brake power is within the
specified limits.

Overheating

Heat sink
temperature too
high

1. Ensure that the ambient temperature falls within the
specified temperature range.

2. Make sure that the ventilation holes are not obstructed.

3. Remove any foreign objects from the heatsinks and check
for possible dirty heat sink fins.

4. Check the fan and clean it.

5. Provide enough spacing for adequate ventilation.

Low voltage

The AC motor
drive detects that
the DC bus voltage
has fallen below its
minimum value.

1. Check whether the input voltage falls within the AC motor
drive rated input voltage range.

2. Check whether the motor has sudden load.

3. Check for correct wiring of input power to R-S-T (for 3-phase
models) without phase loss.

Overload

The AC motor
drive detects
excessive drive
output current.

1. Check whether the motor is overloaded.

2. Reduce torque compensation setting in Pr.7-02.

3. Take the next higher power AC motor drive model.

NOTE: The AC motor drive can withstand up to 150% of the

rated current for a maximum of 60 seconds.

Overload 1

Internal electronic
overload trip

1. Check for possible motor overload.

2. Check electronic thermal overload setting.

3. Use a higher power motor.

4. Reduce the current level so that the drive output current
does not exceed the value set by the Motor Rated Current
Pr.7-00.

Return to the factory.

Communication
Error

1. Check the RS485 connection between the AC motor drive

and RS485 master for loose wires and wiring to correct pins.

2. Check if the communication protocol, address, transmission

speed, etc. are properly set.

3. Use the correct checksum calculation.

4. Please refer to group 9 in the chapter 5 for detail information.

Over-current
during
acceleration

1. Short-circuit at motor output: Check for possible poor

insulation at the output lines.

2. Torque boost too high: Decrease the torque compensation

setting in Pr.7-02.

3. Acceleration Time too short: Increase the Acceleration Time.

4. AC motor drive output power is too small: Replace the AC

motor drive with the next higher power model.

Over-current
during
deceleration

1. Short-circuit at motor output: Check for possible poor

insulation at the output line.

2. Deceleration Time too short: Increase the Deceleration Time.

3. AC motor drive output power is too small: Replace the AC

motor drive with the next higher power model.

Over-current
during steady
state operation

1. Short-circuit at motor output: Check for possible poor

insulation at the output line.

2. Sudden increase in motor loading: Check for possible motor

stall.

3. AC motor drive output power is too small: Replace the AC

motor drive with the next higher power model.

External Fault

1. Input EF (N.O.) on external terminal is closed to GND. Output

U, V, W will be turned off.

2. Give RESET command after fault has been cleared.

Emergency stop

1. When the multi-function input terminals MI1 to MI6 are set to

emergency stop (setting 19 or 20), the AC motor drive stops
output U, V, W and the motor coasts to stop.

2. Press RESET after fault has been cleared.

Internal EEPROM

Auto accel/decel
failure

1. Check if the motor is suitable for operation by AC motor drive.

2. Check if the regenerative energy is too large.

3. Load may have changed suddenly.

Ground fault

When (one of) the output terminal(s) is grounded, short circuit
current is more than 50% of AC motor drive rated current, the
AC motor drive power module may be damaged.

NOTE: The short circuit protection is provided for AC
motor drive protection, not for protection of the user.

1. Check whether the IGBT power module is damaged.

2. Check for possible poor insulation at the output line.

External Base
