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.
0041 POSITION ERROR
(0x8500)
Calculated position error, 4.19
POS ERROR, exceeds defined
position error supervision
window. Motor is stalled.
Check supervision window setting, parameter
71.06 POS ERR LIM.
Check that no torque limit is exceeded during
positioning.
0043 POSITION ERROR MIN
(0x8582)
Actual position value exceeds
defined minimum position
value.
Check minimum position setting, parameter
60.14 MINIMUM POS.
Limit can be exceeded because
no homing (or preset function)
has been performed.
Perform homing (or preset function).
0044 POSITION ERROR MAX
(0x8583)
Actual position value exceeds
defined maximum position
value.
Check maximum position setting, parameter
60.13 MAXIMUM POS.
Limit can be exceeded because
no homing (or preset function)
has been performed.
Perform homing (or preset function).
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 on page 205.
Check cable connections.
Check if communication master can
communicate.
