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.
