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 actual encoder
interface 1 (FEN-xx) installed in drive
Slot 1/2 (parameter 09.20 Option slot1 /
09.21 Option slot2).
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 actual encoder
interface 1 (FEN-xx) installed in drive
Slot 1/2 (parameter 09.20 Option slot1 /
09.21 Option slot2).
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.
2027 FEN TEMP MEAS
FAILURE
(0x7385)
Error in temperature
measurement when
temperature sensor (KTY or
PTC) connected to encoder
interface FEN-xx is used.
Check that parameter 31.02 Mot temp1
src / 31.06 Mot temp2 src setting
corresponds to actual encoder interface
installation (09.20 Option slot1 / 09.21
Option slot2):
If one FEN-xx module is used:
- Parameter 31.02 Mot temp1 src / 31.06
Mot temp2 src must be set either to KTY
1st FEN or PTC 1st FEN. The FEN-xx
module can be in either Slot 1 or Slot 2.
If two FEN-xx modules are used:
- When parameter 31.02 Mot temp1 src /
31.06 Mot temp2 src is set to KTY 1st
FEN or PTC 1st FEN, the encoder
installed in drive Slot 1 is used.
- When parameter 31.02 Mot temp1 src /
31.06 Mot temp2 src is set to KTY 2nd
FEN or PTC 2nd FEN, the encoder
installed in drive Slot 2 is used.
Error in temperature
measurement when KTY
sensor connected to encoder
interface FEN-01 is used.
FEN-01 does not support temperature
measurement with KTY sensor. Use PTC
sensor or other encoder interface
module.
