0040 ENCODER2
(0x7381) Encoder 2 feedback fault See fault ENCODER1.
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 = (2)
ENDAT or (4) SSI
and
91.30 ENDAT MODE = (1)
CONTINUOUS (or 91.25 SSI
MODE = (1) CONTINUOUS ).]
If possible, use single position transfer
instead of continuous position transfer (i.e. if
encoder has incremental sin/cos signals):
- Change parameter
91.25 SSI MODE / 91.30
ENDAT MODE to value (0) INITIAL POS. .
Otherwise use Endat/SSI encoder as
encoder 1:
- Change parameter
90.01 ENCODER 1 SEL
to value (3) FEN-11 ABS and parameter
90.02 ENCODER 2 SEL to value (0) NONE .
Note: The new setting will only take effect
after parameter 90.10 ENC PAR REFRESH is
used or after the JCU control unit is powered
up the next time.
0045 FIELDBUS COMM
(0x7510)
Programmable fault:
50.02
COMM LOSS FUNC
Cyclical communication
between drive and fieldbus
adapter module or between
PLC and fieldbus adapter
module is lost. Check status of fieldbus communication. See
appropriate User’s Manual of fieldbus adapter
module.
Check fieldbus parameter settings. See
parameter group
50 FIELDBUS on page 149 .
Check cable connections.
Check if communication master can
communicate.

0047 MOTOR OVERTEMP
(0x4310)
Programmable fault:
45.01
MOT TEMP PROT
Estimated motor temperature
(based on motor thermal model)
has exceeded fault limit defined
by parameter
45.04 MOT TEMP
FLT LIM .
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
45.06 … 45.08 and 45.10 MOT
THERM TIME .
Measured motor temperature
has exceeded fault limit defined
by parameter
45.04 MOT TEMP
FLT LIM .
Check that actual number of sensors
corresponds to value set by parameter
45.02
MOT TEMP SOURCE .
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.
0049 AI SUPERVISION
(0x8110)
Programmable fault:
13.12
AI SUPERVISION
Analogue input AI1 or AI2 signal
has reached limit defined by
parameter
13.13 AI SUPERVIS
ACT .
Check analogue input AI1/2 source and
connections.
Check analogue input AI1/2 minimum and
maximum limit settings, parameters
13.02
and 13.03 / 13.07 and 13.08 .
