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.)
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 there are no power factor
correction capacitors or surge absorbers
in motor cable.
Cycle the power to the drive.
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.
3130
Input phase loss Programmable fault:
31.21 Supply phase loss
Intermediate circuit DC voltage is
oscillating due to missing input power
line phase or blown fuse.
Check input power line fuses. Check for
loose power cable connections.
Check for input power supply
imbalance.
3181
Wiring or earth fault Programmable
fault: 31.23 Wiring or earth fault
Incorrect input power and motor cable
connection (ie. input power cable is
connected to drive motor connection).
Check input power connections.
3210 DC link overvoltage
Excessive intermediate circuit DC
voltage.
Check that overvoltage control is on
(parameter 30.30 Overvoltage control).
Check that the supply voltage matches
the nominal input voltage of the drive.
Check the supply line for static or
transient overvoltage.
Check brake chopper and resistor (if
present).
Check deceleration time.
Use coast-to-stop function (if
applicable). Retrofit drive with brake
chopper and brake resistor.
Check that the brake resistor is
dimensioned properly and the
resistance is between acceptable range
for the drive.
3220 DC link undervoltage
Intermediate circuit DC voltage is not
sufficient because of a missing supply
phase, blown fuse or fault in the rectifier
bridge.
Check supply cabling, fuses and
switchgear.
3381
Output phase loss Programmable fault:
31.19 Motor phase loss
Motor circuit fault due to missing motor
connection (all three phases are not
connected).
Connect motor cable.
4110 Control board temperature Control board temperature is too high.
Check proper cooling of the drive. Check
the auxiliary cooling fan.
4210 IGBT over temperature
Estimated drive IGBT temperature is
excessive.
Check ambient conditions. Check air
flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
