Cause
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.
The settings of drive-to-drive
link configuration parameters
(group 57) are incompatible.
No speed feedback is received.
Communication between drive
and option module (FEN-xx
and/or FIO-xx) is lost.
What to do
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.
Check the settings of the parameters in group
57 D2D COMMUNICATION.
Check the settings of the parameters in group
22 SPEED FEEDBACK.
Check encoder installation. See the
description of fault 0039 (ENCODER1) for
more information.
Check that option modules are properly
connected to Slot 1 and (or) Slot 2.
Check that option modules or Slot 1/2
connectors are not damaged. To determine
whether module or connector is damaged:
Test each module individually in Slot 1 and
Slot 2.
