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 time. See parameter
group 25 SPEED REF RAMP on page 139.
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 OVERVOLTAGE CTRL.
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.
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: 46.05
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.
