Fault messages generated by the drive

Code Fault
(fieldbus code)
0001 OVERCURRENT
(0x2310)
0002 DC OVERVOLTAGE
(0x3210)
0004 SHORT CIRCUIT
(0x2340)
0005 DC UNDERVOLTAGE
(0x3220)
0006 EARTH FAULT
(0x2330)
Programmable fault:
30.05 Earth fault
0007 FAN FAULT
(0xFF83)
0008 IGBT OVERTEMP
(0x7184)
Cause
Output current has exceeded
internal fault limit.
Excessive intermediate circuit
DC voltage
Short-circuit in motor cable(s)
or motor
Intermediate circuit DC voltage
is not sufficient due to missing
mains phase, blown fuse or
rectifier bridge internal fault.
Drive has detected load
unbalance typically due to
earth fault in motor or motor
cable.
Fan is not able to rotate freely
or fan is disconnected. Fan
operation is monitored by
measuring fan current.
Drive temperature based on
thermal model has exceeded
internal fault limit.
Fault tracing 299
What to do
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).
Check that overvoltage controller is on,
parameter 47.01 Overvolt
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.
Check motor and motor cable.
Check there are no power factor
correction capacitors or surge absorbers
in motor cable.
Check mains supply and fuses.
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.
Check fan operation and connection.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against unit power.
