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 RESOLVER CONF on
page 234.
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.
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.
2032 ENCODER 2 CABLE
(0x738A)
Encoder 2 cable fault detected. Check cable between FEN-xx interface and
encoder 2. After any modifications in cabling,
re-configure interface by switching drive
power off and on, or by activating parameter
90.10 ENC PAR REFRESH.
2033 D2D COMMUNICATION
(0x7520)
Programmable fault: 57.02
COMM LOSS FUNC
On the master drive: The drive
has not been replied to by an
activated follower for five
consecutive polling cycles.
Check that all drives that are polled
(parameters 57.04 and 57.05) on the drive-to-
drive link are powered, properly connected to
the link, and have the correct node address.
Check the drive-to-drive link wiring.
On a follower drive: The drive
has not received new reference
1 and/or 2 for five consecutive
reference handling cycles.
Check the settings of parameters 57.06 and
57.07 on the master drive.
Check the drive-to-drive link wiring.
