(0x8480)
Cause
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.
Motor is operating in stall region
because of, eg, excessive load
or insufficient motor power.
No speed feedback is received.
What to do
Check the connections between the JCU
Control Unit and the power unit.
If the JCU is powered from an external
supply, ensure that parameter
UNIT SUPPLY is set to (1) External
Contact your local ABB representative.
Informative alarm.
Informative alarm.
Check that 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.
Check that the drive is sized correctly for the
motor.
Check the settings of the parameters in group
57.
Check motor load and drive ratings.
Check fault function parameters.
Check the settings of the parameters in group
22.
Check encoder installation. See the
description of fault 0039 (ENCODER1) for
more information.
Check encoder cabling. See the descriptions
of alarms 2031 (ENCODER 1 CABLE) and
2032 (ENCODER 2 CABLE) for more
information.
