Fault / Aux. code
Cause
What to do
1080
Backup/Restore timeout
Panel or PC tool has
failed to communicate
with the drive when
backup was being
made or restored.
Request backup or restore again.
1081
Rating ID fault
Drive software has not
been able to read the
rating ID of the drive.
Reset the fault to make the drive try to
reread the rating ID.
If the fault reappears, cycle the power
to the drive. You may have to be
repeat this. If the fault persists,
contact your local ABB representative.
2310
Overcurrent
Output current has
exceeded internal fault
limit.
In addition to an actual
overcurrent situation,
this fault may also be
caused by an earth
fault or supply phase
loss.
Check motor load.
Check acceleration times in
parameter group
23 Speed reference
ramp
(speed control) or
28 Frequency
reference chain
(frequency control).
Also check parameters
46.01 Speed
scaling, 46.02 Frequency scaling
and
46.03 Torque scaling
.
Check motor and motor cable
(including phasing and delta/star
connection).
Check there are no contactors
opening and closing in motor cable.
Check that the start-up data in
parameter group 99 corresponds to
the motor rating plate.
Check that there are no power factor
correction capacitors or surge
absorbers in motor cable.
Check for an earth fault in motor or
motor cables by measuring the
insulation resistances of motor and
motor cable. See
.
2330
Earth leakage
Programmable fault:
31.20
Earth fault
Drive has detected load
unbalance typically due
to earth fault in motor
or motor cable.
Check there are no power factor
correction capacitors or surge
absorbers in motor cable.
Check for an earth fault in motor or
motor cables by measuring the
insulation resistances of motor and
motor cable.
Try running the motor in scalar control
mode if allowed. (See parameter
99.04 Motor control mode
.)
If no earth fault can be detected,
contact your local ABB representative.
