2023 ENCODER 2 FAILURE
(0x7381)
2024 LATCH POS 1 FAILURE
(0x7382)
Fault tracing
Cause
Encoder 2 has been activated
by parameter but the encoder
interface (FEN-xx) cannot be
found.
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 = (1)
CONTINUOUS (or 91.25 SSI
MODE = (1) CONTINUOUS).]
Position latch 1 from encoder 1
or 2 has failed.
What to do
Check parameter
setting corresponds to encoder interface 2
(FEN-xx) installed in drive Slot 1/2 (signal
9.20 OPTION SLOT 1
2).
Note: The new setting will only take effect
after parameter
used or after the JCU control unit is powered
up the next time.
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
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 latch source parameter settings:

PROBE2. Note that zero pulse is not always
supported. *
Check that appropriate encoder interface 1/2
is activated by parameter
SEL / 90.02 ENCODER 2
Note: The new setting will only take effect
after parameter
used or after the JCU control unit is powered
up the next time.
* - Zero pulse is supported when TTL input of
encoder interface module is selected (i.e. par.
90.01/90.02 = (1) FEN-01
TTL, (4) FEN-11 TTL
- Zero pulse is supported when absolute
encoder input of encoder interface module is
selected and zero pulse is enabled (i.e.
90.01/90.02 = (3) FEN-11 ABS
(0) NONE / (1) COMMUT SIG
TRUE).
- Zero pulse is not supported when resolver
input is selected (i.e.
21 RES).
