Preface
Thank you for choosing DELTA’s high-performance VFD-M Series. The VFD-M 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-M User Manual
on the CD supplied with the drive.
DANGER!
1.
2.
AC input power must be disconnected before any wiring to the AC motor drive is made.
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 turned off before
opening the AC motor drive and wait ten minutes for the capacitors to discharge to safe voltage
levels.
3.
4.
Never reassemble internal components or wiring.
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.
6.
7.
Ground the VFD-M 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.
VFD-M series is used only to control variable speed of 3-phase induction motors, NOT for 1-
phase motors or other purpose.
VFD-M series shall NOT be used for life support equipment or any life safety situation.
WARNING!
1.
2.
DO NOT use Hi-pot test for internal components. The semi-conductor used in AC motor drive
easily damage by high-pressure.
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.
2.
Some parameters settings can cause the motor to run immediately after applying power.
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.
4.
5.
Only use AC motor drives within specification. Failure to comply may result in fire, explosion or
electric shock.
To prevent personal injury, please keep children and unqualified people away from the
equipment.
When the motor cable between 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 AC motor drive must be ≤240V for 230V models (≤120V for 115V models,
≤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).

1. Check whether the motors horsepower corresponds to the
AC drive output power.
2. Check the wiring connections between the AC drive and
motor for possible short circuits.
Over current
3. Increase the Acceleration time (Pr.10, Pr.12).
4. Check for possible excessive loading conditions at the motor.
5. If there are any abnormal conditions when operating the AC
drive after short-circuit being removed, it should be sent back
to manufacturer.
Abnormal increase
in current.
1. Check whether the input voltage falls within the rated AC
drive input voltage.
2. Check for possible voltage transients.
3. Bus over-voltage may also be caused by motor regeneration.
Either increase the decel time or add an optional brake
resistor.
Over voltage
The DC bus voltage
has exceeded its
maximum allowable
value.
4. Check whether the required braking power is within the
specified limits.
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.
Overheating
Heat sink
temperature too
high
5. Provide enough spacing for adequate ventilation.
Low voltage
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.
The AC motor drive
detects that the DC
bus voltage has
fallen below its
minimum value.
1. Check whether the motor is overloaded.
2. Reduce torque compensation setting in Pr.54.
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
The AC motor drive
detects excessive
drive output current.
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.52.
Overload 1
Internal electronic
overload trip
1. Reduce the motor load.
2. Adjust the over-torque detection setting to an appropriate
setting.
Overload 2
Motor overload.

Corrective Actions
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.54.
Over-current
during
acceleration
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.
1. Short-circuit at motor output: Check for possible poor
insulation at the output line.
2. Deceleration Time too short: Increase the Deceleration Time.
Over-current
during
deceleration
3. AC motor drive output power is too small: Replace the AC
motor drive with the next higher power model.
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.
Over-current
during steady state
operation
1. Turn off the power.
2. Check whether the input voltage falls within the rated AC
drive input voltage.
Internal EEPROM
can not be
programmed.
3. Turn on the power.
1. Check the connections between the main control board and
the power board
2. Reset the drive to the factory settings.
Internal EEPROM
can not be read.
1. Input EF (N.O.) on external terminal is closed to GND. Output
U, V, W will be turned off.
External Fault
2. Give RESET command after fault has been cleared.
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.
Auto accel/decel
failure
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.
Ground fault
1. Check whether the IGBT power module is damaged.
2. Check for possible poor insulation at the output line.
1. Check the connection between the AC drive and computer
for loose wires.
2. Check if the communication protocol is properly set.
Communication
error (see Pr.92)
1. When the external input terminal (B.B) is active, the AC
motor drive output will be turned off.
2. Deactivate the external input terminal (B.B) to operate the AC
motor drive again.
