ABB ACL30 - Fault Messages Generated by the Drive

Fault tracing 299
Fault messages generated by the drive
Code Fault Cause What to do
0001
OVERCURRENT Output current has
exceeded the internal fault
limit.
Check motor load.
Check acceleration time. See
parameter group 25 ACC/DEC
RAMP on page 236.
Check the motor and motor cable
(including phasing and delta/star
connection).
Check that the start-up data in
parameter group 99 START-UP
DATA corresponds to the motor
rating plate.
Check that there are no power
factor correction capacitors or
surge absorbers in the motor cable.
Check the encoder cable (including
phasing).
0002
DC
OVERVOLTAGE
Excessive intermediate
circuit DC voltage.
Check the mains for static or
transient overvoltage.
Check the brake chopper and
resistor (if used).
Check the deceleration time.
Use the coast-to-stop function (if
applicable).
Retrofit the frequency converter
with the brake chopper and brake
resistor.
0003
DEVICE
OVERTEMP
Measured drive
temperature has exceeded
the internal fault limit.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-
up.
Check motor power against unit
power.
0004
SHORT CIRCUIT Short-circuit in the motor
cable(s) or motor.
Check the motor and motor cable.
Check that there are no power
factor correction capacitors or
surge absorbers in the motor cable.
0005
DC
UNDERVOLTAGE
Intermediate circuit DC
voltage is not sufficient due
to missing mains phase,
blown fuse or rectifier
bridge internal fault.
Check mains supply and fuses.
