392 Fault tracing
5081 Auxiliary fan broken An auxiliary cooling fan
(connected to the fan
connectors on the control unit)
is stuck or disconnected.
Check the auxiliary code.
Check auxiliary fan(s) and connection(s).
Replace fan if faulty.
Make sure the front cover of the drive is
in place and tightened.
If the commissioning of the drive requires
th the cover is off, activate parameter
31.36 Aux fan fault bybass within 2 min
from control unit reboot to temporarily
suppress the fault.
Reboot the control unit (using parameter
96.08 Control board boot) or by cycling
power.
0001 Auxiliary fan 1 broken.
0002 Auxiliary fan 2 broken.
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 245).
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.
5098 SMT circuit
malfunction
Safe motor temperature fault is
generated and STO
event/fault/warning is not
generated.
Note: If only one STO channel
is opened, fault 5090 STO
hardware failure is generated.
Check connection between the relay
output of the module and the STO
terminal.
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
