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.
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
(speed
control),
(torque control) or
(frequency control). Also
check parameters
,
and
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
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
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
.)
If no earth fault can be detected, contact
your local ABB representative.
