Cause
What to do
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 (select
at
parameter
). If the fault
persists, contact your local ABB
representative.
2310
Overcurrent
Output current has exceeded
internal fault limit.
Check motor load.
Check acceleration times in
parameter group
(speed control) or
(frequency control). Also check
parameters
and
.
Check motor and motor cable
(including phasing and delta/star
connection).
Check that the start-up data in
parameter group
(page
) corresponds to the
motor rating plate.
Check that there are no power
factor correction capacitors or
surge absorbers in motor cable.
Check encoder cable (including
phasing).
2330
Earth leakage
Programmable 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 that there is no earth fault in
motor or motor cables:
Measure insulation resistances of
motor and motor cable.
If no earth fault can be detected,
contact your local ABB
representative.
2340
Short circuit
Short-circuit in motor
cable(s) or motor
Check motor and motor cable.
Check there are no power factor
correction capacitors or surge
absorbers in motor cable.
2381
IGBT overload
Excessive IGBT junction to
case temperature. This fault
protects the IGBT(s) and can
be activated by a short circuit
in the motor cable.
Check motor cable.
2392
BU earth leakage
Total earth leakage of inverter
modules is excessive.
Check there are no power factor
correction capacitors or surge
absorbers in motor cable.
Measure insulation resistances of
motor cables and motor.
Contact your local ABB
representative.
