Cause
Encoder 2 feedback fault
EnDat or SSI encoder is used in
continuous mode as encoder 2.
[I.e. 90.02 ENCODER 2 SEL
(3) FEN-11 ABS
and
91.02 ABS ENC INTERF
EnDat or (4) SSI
and
91.30 ENDAT MODE
Continuous (or 91.25 SSI
MODE = (1) Continuous).]
Cyclical communication
between drive and fieldbus
adapter module or between
50.02
PLC and fieldbus adapter
module is lost.
Drive internal fault
Estimated motor temperature
(based on motor thermal model)
has exceeded fault limit defined
45.01
by parameter 45.04 MOT TEMP
FLT LIM.
Measured motor temperature
has exceeded fault limit defined
by parameter 45.04 MOT TEMP
FLT LIM.
Broken wire in the temperature
sensor.
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 (3) FEN-11 ABS
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 TIME.
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 the temperature sensor connection.
