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
244
).
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 e.g. 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.
5089
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.
5098
I/O communication
loss
Communication failure to
standard I/O.
Try resetting the fault or cycle the power
to 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
6306
FBA A mapping file
Fieldbus adapter A mapping
file read error.
Contact your local ABB representative.
