Fault tracing 359
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.
