Cause
Encoder 2 cable fault detected. Check cable between FEN-xx interface
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.
Communication errors
detected between the JCU
Control Unit and the power unit
of the drive.
Restoration of backed-up
parameters failed.
Current measurement
calibration will occur at next
start.
Autophasing will occur at next
start.
Drive has detected load
unbalance typically due to
earth fault in motor or motor
cable.
A fault is to be autoreset.
The motor configuration
parameters are set incorrectly.
The drive is not dimensioned
correctly.
The settings of drive-to-drive
link configuration parameters
(group 57) are incompatible.
What to do
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.
Check that all drives that are polled
(parameters 57.04 Follower mask 1
57.05 Follower mask 2) on the drive-to-
drive link are powered, properly
connected to the link, and have the
correct node address.
Check the drive-to-drive link wiring.
Check the settings of parameters
Ref 1 src and 57.07 Ref 2
master drive.
Check the drive-to-drive link wiring.
Contact your local ABB representative.
Check the connections between the JCU
Control Unit and the power unit.
Contact your local ABB representative.
Informative alarm.
Informative alarm.
Check there are no power factor
correction capacitors or surge absorbers
in motor cable.
Check for an earth fault in motor or motor
cables by measuring the insulation
resistances of motor and motor cable.
If no earth fault can be detected, contact
your local ABB representative.
Informative alarm. See parameter group
32 Automatic reset.
Check the settings of the motor
configuration parameters in group 99.
Check that the drive is sized correctly for
the motor.
Check the settings of the parameters in
group 57 D2D communication.
