2310 Overcurrent
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.
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
23 Speed reference ramp
group
26 Torque reference
(speed control),
chain
(torque control) or
reference chain
(frequency control).
Also check parameters
scaling 46.02 Frequency scaling
,
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
99 Motor data
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
installation Checking the
, section
insulation of the assembly
hardware manual of the drive.
