Cause
Panel or PC tool has failed to
communicate with the drive
when backup was being made
or restored.
Drive software has not been
able to read the rating ID of the
drive.
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).
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.
Drive has detected load
unbalance typically due to
31.20
earth fault in motor or motor
cable.
What to do
Request backup or restore again.
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.
Try performing the current calibration
again.
If the fault persists, contact your local
ABB representative.
Check motor load.
Check acceleration times in parameter
group 23 Speed reference ramp (speed
control), 26 Torque reference chain
(torque 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 Motor data 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.
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.
