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.
2030 RESOLVER
AUTOTUNE ERR
(0x7388)
Resolver autotuning routines,
which are automatically started
when resolver input is
activated for the first time,
have failed.
Check cable between resolver and
resolver interface module (FEN-21) and
order of connector signal wires at both
ends of cable.
Check resolver parameter settings.
For resolver parameters and information,
see parameter group 92 Resolver conf.
Note: Resolver autotuning routines
should always be performed after
resolver cable connection has been
modified. Autotuning routines can be
activated by setting parameter 92.02 Exc
signal ampl or 92.03 Exc signal freq, and
then setting parameter 90.10 Enc par
refresh to Configure.
2031 ENCODER 1 CABLE
(0x7389)
Encoder 1 cable fault detected. Check cable between FEN-xx interface
and encoder 1. After any modifications in
cabling, re-configure interface by
switching drive power off and on, or by
activating parameter 90.10 Enc par
refresh.
