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 .
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 Follower mask 1 and
57.05 Follower mask 2 ) 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
Ref 1 src and 57.07 Ref 2 src ) on the
master drive.
Check the drive-to-drive link wiring.
2034 D2D BUFFER
OVERLOAD
(0x7520)
Programmable fault:
57.02 Comm loss func
Transmission of drive-to-drive
references failed because of
message buffer overflow. Contact your local ABB representative.
2035 PS COMM
(0x5480) Communication errors
detected between the JCU
Control Unit and the power unit
of the drive. Check the connections between the JCU
Control Unit and the power unit.
2036 RESTORE
(0x6300) Restoration of backed-up
parameters failed. Contact your local ABB representative.
2037 CUR MEAS
CALIBRATION
(0x2280) Current measurement
calibration will occur at next
start. Informative alarm.
2038 AUTOPHASING
(0x3187) Autophasing will occur at next
start. Informative alarm.
