2021 NO MOTOR DATA
(0x6381)
Parameters in group 99 have
not been set.
Check that all the required parameters in
group 99 have been set.
Note: It is normal for this alarm to appear
during the start-up until the motor data is
entered.
2022 ENCODER 1 FAILURE
(0x7301)
Encoder 1 has been activated
by parameter but the encoder
interface (FEN-xx) cannot be
found.
Check parameter 90.01 ENCODER 1 SEL
setting corresponds to encoder interface 1
(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.
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.
