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.

ENCODER 1
FAILURE (0x7301)
Encoder 1 has been activated
by parameter but the encoder
interface (FEN-xx) cannot be
found.
Check parameter
setting corresponds to actual encoder
interface 1 (FEN-xx) installed in drive
Slot 1/2 (parameter
/
Note:
The new setting will only take
effect after parameter
is used or after the JCU Control
Unit is powered up the next time.

ENCODER 2
FAILURE (0x7381)
Encoder 2 has been activated
by parameter but the encoder
interface (FEN-xx) cannot be
found.
Check parameter
setting corresponds to actual encoder
interface 1 (FEN-xx) installed in drive

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
/
setting
corresponds to actual encoder interface
installation (
/
If one FEN-xx module is used:
- Parameter
must be set either to
. The FEN-xx
module can be in either Slot 1 or Slot 2.
If two FEN-xx modules are used:
- When parameter
is set to
or
, the encoder
installed in drive Slot 1 is used.
- When parameter
is set to
or
, 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.
