Cause
Encoder 1 cable fault detected. Check cable between FEN-xx interface
Encoder 2 cable fault detected. Check cable between FEN-xx interface
Configuration of the drive-to-
drive link has failed for a
reason other than those
indicated by alarm A-2042, for
example start inhibition is
requested but not granted.
On the master drive: The drive
has not been replied to by an
activated follower for five
consecutive polling cycles.
On a follower drive: The drive
has not received new
reference 1 and/or 2 for five
consecutive reference
handling cycles.
Transmission of drive-to-drive
references failed because of
message buffer overflow.
Resettable fault generated by
a technology library.
Permanent fault generated by
a technology library.
Generic Drive Communication
Profile trip command.
The drive does not have a
functionality requested by
PLC, or requested functionality
has not been activated.
Motor is operating in stall
region because of e.g.
excessive load or insufficient
motor power.
Overload or underload limit
has been exceeded.

What to do
and encoder 1. After any modifications in
cabling, re-configure interface by
switching drive power off and on, or by
activating parameter 90.10 Enc par
refresh.
and encoder 2. After any modifications in
cabling, re-configure interface by
switching drive power off and on, or by
activating parameter 90.10 Enc par
refresh.
Contact your local ABB representative.
Check that all drives that are polled
