Code (hex)
Fault / Aux. code
Cause
What to do
42F1
IGBT temperature
Drive IGBT temperature is excessive.
Check ambient conditions. Check air
flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive
power.
4310
Excess temperature
Power unit module temperature is
excessive.
Check ambient conditions. Check air
flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive
power.
4380
Excess temperature difference
High temperature difference between
the IGBTs of different phases.
Check the motor cabling.
Check cooling of drive module(s).
4981
External temperature 1
(Editable message text)
Measured temperature 1 has
exceeded fault limit.
Check the value of parameter
35.02
Measured temperature 1
.
Check the cooling of the motor (or
other equipment whose temperature
is being measured).
4982
External temperature 2
(Editable message text)
Measured temperature 2 has
exceeded fault limit.
Check the value of parameter
35.03
Measured temperature 2
.
Check the cooling of the motor (or
other equipment whose temperature
is being measured).
5081
Auxiliary fan broken
An auxiliary cooling fan (connected to
the fan connectors on the control
unit) is stuck or disconnected.
Check auxiliary fan(s) and
connection(s). Replace fan if faulty.
Make sure the front cover of the drive
module is in place and tightened.
Reboot the control unit (using
parameter
96.08 Control board boot
) or by
cycling power.
5090
STO hardware failure
STO hardware diagnostics has
detected hardware failure.
Contact your local ABB
representative for hardware
replacement.
5091
Safe torque off Programmable fault:
31.22 STO indication run/stop
Safe torque off function is active, ie.
safety circuit signal(s) connected to
connector STO is broken during start
or run.
Check safety circuit connections. For
more information, see chapter The
Safe torque off function in the
Hardware manual of the drive and
description of parameter 31.22 STO
indication run/stop (page 183).
Check the value of parameter 95.04
Control board supply.
5092
PU logic error
Power unit memory has cleared.
Contact your local ABB
representative.
5093
Rating ID mismatch
The hardware of the drive does not
match the information stored in the
memory. This may occur eg. after a
firmware update.
Cycle the power to the drive. You
may have to be repeat this.
5094
Measurement circuit temperature
Problem with internal temperature
measurement of the drive.
Contact your local ABB
representative.
50A0
Fan
Cooling fan stuck or disconnected.
Check fan operation and connection.
Replace fan if faulty.
5681
PU communication
Communication errors detected
between the drive control unit and
the power unit.
Check the connection between the
drive control unit and the power unit.
Check the value of parameter
95.04
Control board supply
.
5682
Power unit lost
Connection between the drive control
unit and the power unit is lost.
Check the connection between the
control unit and the power unit.
5690
PU communication internal
Internal communication error.
Contact your local ABB
representative.
