354 Fault tracing
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 180).
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 I/O communication
loss
Internal standard I/O
communication failure.
Try resetting the fault or reboot the
drive.
50A0 Fan Cooling fan stuck or
disconnected.
Check fan operation and connection.
Replace fan if faulty.
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.
5691 Measurement circuit
ADC
Measurement circuit fault. Contact your local ABB
representative.
5692 PU board powerfail Power unit power supply
failure.
Contact your local ABB
representative.
5693 Measurement circuit
DFF
Measurement circuit fault. Contact your local ABB
representative.
5696 PU state feedback State feedback from output
phases does not match control
signals.
Contact your local ABB
representative.
5697 Charging feedback Charging feedback signal
missing.
Check the feedback signal coming
from the charging system
5698 Unknown PU fault The power unit logic has
generated a fault which is not
known by the software.
Check the logic and software
compatibility.
6181 FPGA version
incompatible
Firmware and FPGA versions
are incompatible.
Reboot the control unit (using
parameter 96.08 Control board boot)
or by cycling power. If the problem
persists, contact your local ABB
representative
