ABB ACQ80-04 User Manual

210 Fault tracing
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.
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
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 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.
3291 DC voltage difference Difference in DC voltages
between parallel-connected
inverter modules.
Contact your local ABB representative
3293 DC unbalance fault DC unbalance. Contact your local ABB representative
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.
