Fault tracing
311
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.
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.
If the JCU is powered from an external
supply, ensure that parameter 95.01 CTRL
UNIT SUPPLY is set to (1) External 24V.
2036 RESTORE
(0x630D)
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: 46.05
EARTH FAULT
Drive has detected load
unbalance typically due to earth
fault in motor or motor cable.
Check that there are no power factor
correction capacitors or surge absorbers in
motor cable.
Check that there is no earth fault in motor or
motor cables:
- measure insulation resistances of motor and
motor cable.
If no earth fault can be detected, contact your
local ABB representative.
