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).]
Calculated position error,
POS ERROR, exceeds defined
position error supervision
window. Motor is stalled.
Actual position value exceeds
defined minimum position
value.
Limit can be exceeded because
no homing (or preset function)
has been performed.
Actual position value exceeds
defined maximum position
value.
Limit can be exceeded because
no homing (or preset function)
has been performed.
Cyclical communication
between drive and fieldbus
adapter module or between
50.02
PLC and fieldbus adapter
module is lost.
Drive internal fault
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.
4.19 Check supervision window setting, parameter
71.06 POS ERR
Check that no torque limit is exceeded during
positioning.
Check minimum position setting, parameter
60.14 MINIMUM
Perform homing (or preset function).
Check maximum position setting, parameter
60.13 MAXIMUM
Perform homing (or preset function).
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.
