Fault tracing 321
Fault messages generated by the drive
Code
Fault (fieldbus code),
other information
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.
0002 DC OVERVOLTAGE
(0x3210)
Excessive intermediate
circuit DC voltage
Check that overvoltage controller is on,
parameter 47.01 Overvolt ctrl.
Check mains for static or transient
overvoltage.
Check deceleration time.
Use coast-to-stop function (if applicable).
0003 DEVICE OVERTEMP
(0x4210)
Measured drive temperature
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.
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.
0013 CURR MEAS GAIN
(0x3183)
Difference between output
phase U2 and W2 current
measurement gain is too
great.
Contact your local ABB representative.
0014 CABLE CROSS CON
(0x3181)
Programmable fault: 30.08
Cross connection
Incorrect input power and
motor cable connection (i.e.
input power cable is
connected to drive motor
connection).
Check input power connections.
