Cause What to do
1080 Backup/Restore
timeout
During backup/restore,
communication is lost between
panel/PC tool and drive.
Request backup or restore again.
1081 Rating ID fault Drive software is not able to read the
drive rating ID.
Reset the fault or cycle the power to
the drive. 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 exceeded the internal
fault limit.
Check the motor load, acceleration
times, motor and motor cable,
encoder cable and there are no power
factor correction capacitors in motor
cable.
2330 Earth leakage 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 and there is
no earth fault in motor or motor
cables.
2340 Short circuit Short-circuit in motor cable(s) or
motor.
Check motor and motor cable and
there are no power factor correction
capacitors or surge absorbers in
motor cable.
2381 IGBT overload Excessive IGBT junction to case
temperature.
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.
3130 Input phase loss Intermediate circuit DC voltage is
oscillating due to missing input power
line phase or blown fuse.
Check input power line fuses and
there is no input power supply
imbalance.
3181 Wiring or earth fault Incorrect input power and motor
cable connection.
Check input power connections.
3210 DC link overvoltage Excessive intermediate circuit DC
voltage.
Check overvoltage control is on,
supply voltage matches the nominal
input voltage of the drive. Check
supply line for static or transient
overvoltage, brake chopper, brake
resistor and deceleration time. Use
coast-to-stop function (if applicable).
3220 DC link undervoltage Intermediate circuit DC voltage is not
sufficient.
Check supply cabling, fuses and
switchgear.
