signal(s) connected to
connector STO is broken
during start or run.
Power unit memory has
cleared.
The hardware of the drive does
not match the information
stored in the memory. This
may occur eg. after a firmware
update.
Problem with internal
temperature measurement of
the drive.
Internal standard I/O
communication failure.
Cooling fan stuck or
disconnected.
Connection between the drive
control unit and the power unit
is lost.
Measurement circuit fault.
Power unit power supply
failure.
Measurement circuit fault.
State feedback from output
phases does not match control
signals.
Charging feedback signal
missing.
The power unit logic has
generated a fault which is not
known by the software.
Firmware and FPGA versions
are incompatible.
Fieldbus adapter A mapping
file read error.
What to do
Contact your local ABB
representative for hardware
replacement.
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
indication run/stop (page 180).
Check the value of parameter
Control board supply.
Contact your local ABB
representative.
Cycle the power to the drive. You may
have to be repeat this.
Contact your local ABB
representative.
Try resetting the fault or reboot the
drive.
Check fan operation and connection.
Replace fan if faulty.
Check the connection between the
control unit and the power unit.
Contact your local ABB
representative.
Contact your local ABB
representative.
Contact your local ABB
representative.
Contact your local ABB
representative.
Check the feedback signal coming
from the charging system
Check the logic and software
compatibility.
Reboot the control unit (using
parameter 96.08 Control board
or by cycling power. If the problem
persists, contact your local ABB
representative
