8.1 Vacon 50X Fault Codes
Table 1 shows the fault codes that may be displayed during Vacon 50X AC drive operation, along with sug-
gestions for recovering from the fault condition.
When faults occur, you can access the status parameters that are saved along with the fault (Advanced
Fault history). To view these parameters, which store the drive’s status at the time of the fault, view Fault
History, and select Last Fault. Press the Shift key while viewing the last fault, and then use the UP and
DOWN arrow keys to scroll through the stored drive status parameters. Press the Shift key again to re-
turn to the programming mode fault parameter.

Consult factory for repair or re-
placement.

Memory problem when re-
flashing the drive’s memo-
ry
Reset drive to factory settings.
Consult VACON.
1, 2, 3 Conflict in drive’s memory
Reset drive to factory settings.
Consult VACON.
4
Unable to write an EE pa-
rameter after a parameter
has been changed through
the keypad or SIO
Reset drive to factory settings.
Consult VACON.
5
The drive is receiving EE
write requests faster than
they can be processed.
This would typically be
caused by writing parame-
ters too frequently through
Modbus.
Slow down the frequency of Mod-
bus writes.

Curr Cali-
br
Current calibra-
tion fault
0
Current calibration fault on
phase T1/U
Check the motor connections to the
terminal strip of the drive and at
the motor.
Have motor checked.
Consult VACON for repair or re-
placement of drive.

5 V supply is below 4 Vdc
for more than 100 ms
Increase resistance between REF
and analog inputs.
Check wiring to REF terminals.
Consult VACON.

Short circuit was detected
on power-up
Remove the short from the power
wiring.
Check for shorted motor.
Consult VACON. 1
Short circuit was detected
during operation
7 MOL MOL contact fault 0
The MOL digital input was
activated, depending on
pull-up or pull-down logic
configuration
Reset MOL contact or remove con-
dition causing the MOL contact ac-
tivation.
8 Model ID ID # out of range 0, 1, 2 Control board is not read-
ing the drive ID properly
Consult VACON for repair or re-
placement.
10
Res Lock-
out
Restart lockout 0
The number of fault re-
starts is greater than the
limit defined in the cus-
tomer parameter.
Check the actual fault in the fault
log and use the appropriate reme-
dy.
11 Ground Ground fault 0
The drive has detected cur-
rent imbalance between
output phases. Imbalance
determined to be current
flow to ground.
Check for unbalanced currents.
Check for grounded motor leads or
motor.
Consult VACON.
Note: Shaded faults are auto-resettable, except where noted.
