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 45.02 MOT TEMP
SOURCE setting corresponds to encoder
interface installation (9.20 OPTION SLOT 1 /
9.21 OPTION SLOT 2):
If one FEN-xx module is used:
- Parameter 45.02 MOT TEMP SOURCE
setting must be either (2) KTY 1st FEN or (5)
PTC 1st FEN. FEN-xx module can be in
either Slot 1 or Slot 2.
If two FEN-xx modules are used:
- When parameter 45.02 MOT TEMP
SOURCE setting is (2) KTY 1st FEN or (5)
PTC 1st FEN, the encoder installed in drive
Slot 1 is used.
- When parameter 45.02 MOT TEMP
SOURCE setting is (3) KTY 2nd FEN or (6)
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.
2028 ENC EMUL MAX FREQ
(0x7386)
TTL pulse frequency used in
encoder emulation.exceeds
maximum allowed limit
(500 kHz).
Decrease parameter 93.21 EMUL PULSE NR
value.
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.
2029 ENC EMUL REF ERROR
(0x7387)
Encoder emulation has failed
due to failure in writing new
(position) reference for
emulation.
Contact your local ABB representative.
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 on page 266.
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 (1)
Configure.
