Fault tracing
Cause
Encoder 1 cable fault detected.
Encoder 2 cable fault detected.
On the master drive: The drive
has not been replied to by an
activated follower for five
57.02
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.
57.02
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.
46.05
The motor configuration
parameters are set incorrectly.
The drive is not dimensioned
correctly.
What to do
Check cable between FEN-xx interface 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.
Check cable between FEN-xx interface 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 and 57.05) 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
57.07 on the 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 that there is no earth fault in motor or
motor cables:
- measure insulation resistances of motor and
motor cable.
If no earth fault can be detected, contact your
local ABB representative.
Check the settings of the motor configuration
parameters in group 99 START-UP
Check that the drive is sized correctly for the
motor.
