Issue:
O.CF fault on an ATV31 or ATV312
Product Line:
Altivar, ATV31, ATV312
Environment:
All
Cause:
N/A
Resolution:
O.CF is a phase-to-phase motor short circuit fault. Check motor windings and motor leads for a possible shorting path. A Megger test at a 1,000V of the motor and motor leads should be performed.
You can also try running the drive "open circuit" and see it faults without the motor connected
Other possible related fault codes are OCF and OC.F:
OCF is an overcurrent fault. Possible causes are incorrect settings in the SET and DRC menus, excessive loading on the motor or mechanical binding.
OC.F is an impedance short-circuit fault. This is a detected short-circuit or grounding at the drive output. Check the cables connecting the drive to the motor and the motor insulation. A Megger test at a 1,000V of the motor and motor leads should be performed.

1. Turn off Output Phase Loss (OPL)
2. Power down and disconnect the motor leads from the drive
3. Run the drive at 20, 40, and 60Hz and measure output voltage phase-to-phase checking for balanced voltage
