2023 ENCODER 2 FAILURE
(0x7381) Encoder 2 has been activated
by parameter but the encoder
interface (FEN-xx) cannot be
found. Check parameter 90.02 ENCODER 2 SEL
setting corresponds to encoder interface 2
(FEN-xx) installed in drive Slot 1/2 (signal
9.20 OPTION SLOT 1 / 9.21 OPTION SLOT
2 ).
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.
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.
2026 ENC EMULATION
FAILURE
(0x7384) Encoder emulation error If position value used in emulation is
measured by encoder:
- Check that FEN-xx encoder used in
emulation (
90.03 EMUL MODE SEL )
corresponds to FEN-xx encoder interface 1 or
(and) 2 activated by parameter
90.01
ENCODER 1 SEL / 90.02 ENCODER 2 SEL .
(Parameter 90.01 / 90.02 activates the position
calculation of the used FEN-xx input).
If position value used in emulation is
determined by drive software:
- Check that FEN-xx encoder used in
emulation (
90.03 EMUL MODE SEL )
corresponds to FEN-xx encoder interface 1 or
(and) 2 activated by parameter
90.01
ENCODER 1 SEL / 90.02 ENCODER 2 SEL
(because position data used in emulation is
written to FEN-xx during encoder data
request). Encoder interface 2 is
recommended.
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.
