264 Fault tracing
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.
2039 EARTH FAULT
(0x2330)
Programmable fault:
30.05 Earth fault
Drive has detected load
unbalance typically due to
earth fault in motor or motor
cable.
Check there are no power factor
correction capacitors or surge absorbers
in motor cable.
Check for an earth fault in motor or motor
cables by measuring the insulation
resistances of motor and motor cable.
If no earth fault can be detected, contact
your local ABB representative.
2040 AUTORESET
(0x6080)
A fault is to be autoreset. Informative alarm. See parameter group
32 Automatic reset.
2041 MOTOR NOM VALUE
(0x6383)
The motor configuration
parameters are set incorrectly.
Check the settings of the motor
configuration parameters in group 99.
The drive is not dimensioned
correctly.
Check that the drive is sized correctly for
the motor.
2042 D2D CONFIG
(0x7583)
The settings of drive-to-drive
link configuration parameters
(group 57) are incompatible.
Check the settings of the parameters in
group 57 D2D communication.
