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
(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 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.
2041 MOTOR NOM VALUE
(0x6383)
The motor configuration
parameters are set incorrectly.
Check the settings of the motor configuration
parameters in group 99 START-UP DATA.
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.
2047 SPEED FEEDBACK
(0x8480)
No speed feedback is received. Check the settings of the parameters in group
22 SPEED FEEDBACK.
Check encoder installation. See the
description of fault 0039 (ENCODER1) for
more information.
2048 OPTION COMM LOSS
(0x7000)
Communication between drive
and option module (FEN-xx
and/or FIO-xx) is lost.
Check that option modules are properly
connected to Slot 1 and (or) Slot 2.
Check that option modules or Slot 1/2
connectors are not damaged. To determine
whether module or connector is damaged:
Test each module individually in Slot 1 and
Slot 2.
