ERR
(0x7388)
Cause
Error in temperature
measurement when
temperature sensor (KTY or
PTC) connected to encoder
interface FEN-xx is used.
Error in temperature
measurement when KTY
sensor connected to encoder
interface FEN-01 is used.
TTL pulse frequency used in
encoder emulation.exceeds
maximum allowed limit
(500 kHz).
Encoder emulation has failed
due to failure in writing new
(position) reference for
emulation.
Resolver autotuning routines,
which are automatically started
when resolver input is activated
for the first time, have failed.
What to do
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
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
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
PTC 2nd FEN, the encoder installed in drive
Slot 2 is used.
FEN-01 does not support temperature
measurement with KTY sensor. Use PTC
sensor or other encoder interface module.
Decrease parameter 93.21 EMUL PULSE NR
value.
Note: The new setting will only take effect
after parameter 90.10 ENC PAR REFRESH
used or after the JCU control unit is powered
up the next time.
Contact your local ABB representative.
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
page 170.
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
92.03 EXC SIGNAL FREQ, and then setting
parameter 90.10 ENC PAR REFRESH
