Fault 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 Current measurement
calibration at parameter 99.13). If the
fault persists, contact your local ABB
representative.
2310 Overcurrent Output current has exceeded
internal fault limit.
See A2B1 Overcurrent (page 569).
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.)
With parallel-connected modules, check
the auxiliary code (format XXXY YYZZ).
“Y YY” specifies through which BCU
control unit channel the fault was
received.
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 for cabling
errors.
Check that parameter 99.10 Motor
nominal power has been set correctly.
Check there are no power factor
correction capacitors or surge absorbers
in motor cable.
Check the auxiliary code (format XXXY
YYZZ). With parallel-connected inverter
modules, “Y YY” specifies through which
BCU control unit channel the fault was
received. “ZZ” indicates the location of
the short circuit (0: No detailed
information available, 1: Upper branch of
U-phase, 2: Lower branch of U-phase, 4:
Upper branch of V-phase, 8: Lower
branch of V-phase, 10: Upper branch of
W-phase, 20: Lower branch of W-phase,
other: combinations of the above).
After correcting the cause of the fault,
reboot the control unit (using parameter
96.08 Control board boot) or by cycling
power.
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.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
