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 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
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:
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:
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
).
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:
Motor circuit fault due to
missing motor connection (all
three phases are not
connected).
Connect motor cable.
