What to do
See fault ENCODER1.
If possible, use single position transfer
instead of continuous position transfer (i.e. if
encoder has incremental sin/cos signals):
=
- Change parameter
ENDAT MODE
= (2)
Otherwise use Endat/SSI encoder as
encoder 1:
- Change parameter
= (1)
to value
(or 91.25 SSI
90.02 ENCODER 2 SEL
Note: The new setting will only take effect
after parameter
used or after the JCU control unit is powered
up the next time.
Check status of fieldbus communication. See
appropriate User's Manual of fieldbus adapter
module.
Check fieldbus parameter settings. See
parameter group
Check cable connections.
Check if communication master can
communicate.
Contact your local ABB representative.
Check motor ratings and load.
Let motor cool down. Ensure proper motor
cooling: Check cooling fan, clean cooling
surfaces, etc.
Check value of fault limit.
Check motor thermal model settings,
parameters
THERM
Check that actual number of sensors
corresponds to value set by parameter
MOT TEMP
Check motor ratings and load.
Let motor cool down. Ensure proper motor
cooling: Check cooling fan, clean cooling
surfaces, etc.
Check value of fault limit.
Check analogue input AI1/2 source and
connections.
Check analogue input AI1/2 minimum and
maximum limit settings, parameters
