Fault tracing 299
Fault messages generated by the drive
Code Fault
(fieldbus code) Cause What to do
0001 OVERCURRENT
(0x2310) Output current has exceeded
internal fault limit. Check motor load.
Check acceleration times in parameter
group
22 Speed ref ramp .
Check motor and motor cable (including
phasing and delta/star connection).
Check that the start-up data in parameter
group 99 corresponds to the motor rating
plate.
Check that there are no power factor
correction capacitors or surge absorbers
in motor cable.
Check encoder cable (including
phasing).
0002 DC OVERVOLTAGE
(0x3210) Excessive intermediate circuit
DC voltage Check that overvoltage controller is on,
parameter
47.01 Overvolt ctrl .
Check that the supply (input power)
voltage matches the drive nominal input
voltage.
Check mains for static or transient
overvoltage.
Check brake chopper and resistor (if
used).
Check deceleration time.
Use coast-to-stop function (if applicable).
Retrofit frequency converter with brake
chopper and brake resistor.
0004 SHORT CIRCUIT
(0x2340) Short-circuit in motor cable(s)
or motor Check motor and motor cable.
Check there are no power factor
correction capacitors or surge absorbers
in motor cable.
0005 DC UNDERVOLTAGE
(0x3220) Intermediate circuit DC voltage
is not sufficient due to missing
mains phase, blown fuse or
rectifier bridge internal fault. Check mains supply and fuses.
0006 EARTH FAULT
(0x2330)
Programmable fault:
30.05 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 that there is no earth fault in motor
or motor cables:
- measure insulation resistances of motor
and motor cable.
If no earth fault can be detected, contact
your local ABB representative.
0007 FAN FAULT
(0xFF83) Fan is not able to rotate freely
or fan is disconnected. Fan
operation is monitored by
measuring fan current. Check fan operation and connection.
0008 IGBT OVERTEMP
(0x7184) Drive temperature based on
thermal model has exceeded
internal fault limit. Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against unit power.
