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 is not 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.
2281 Calibration Measured offset of output
phase current measurement or
difference between output
phase U2 and W2 current
measurement is too great (the
values are updated during
current calibration). Try performing the current calibration
again.
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
parameter
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 chapter
Electrical installation ,
section Checking the insulation of the
assembly in the Hardware manual of the
drive.
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.
