8.1 Vacon 500X Fault Codes
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, access Fault
History by pressing SHIFT and ENTER, 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 return to the programming mode fault parameter.
A great deal of information is contained in the Fault History log for the last fault, and also the previous nine
faults, including the following:
Output Frequency Total Run Time DI Status Drive Status 2
Drive Load DC Bus Voltage Output Status
Drive Status Adv Fault Code Vin1 Status
Drive Warning Cntl Board Temp Cin Status
Output Voltage Drive Power Out Vin2 Status
Output Current Fault Date Vmet Status
Load Torque Fault Time Imet Status
Drive Temp Drive Warning 2 Actual Carrier
For questions about accessing fault codes, and for advanced troubleshooting problems, please contact

Table 1 shows the fault codes that may be displayed during Vacon 500x AC drive operation, along with

keypad or SIO
•Reset drive to factory
settings.
•Consult factory.
5
The drive is receiving EE write
requests faster than they can
be processed. This would
typically be caused by writing
parameters too frequently
through Modbus.
Slow down the
frequency of Modbus
writes.
3 Curr Calibr

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 factory for repair
or replacement of drive.

phase T2/V
2

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