What causes numbers to flash and OCF error on ATV320 drive?

Issue:
Numbers flash and getting OCF error on ATV320 drive.

Product Line:
Altivar 320

Environment:
All

Cause:
N/A

Resolution:
Motor running higher than the current limit setting on the drive.  This is expected to be linear to the motor frequency so 30hz should be around 50%.  Verify rotation, look for mechanical blockage.  Ensure the load is not more than the motor can handle. Make sure all the motor parameters match the motor. Could trying increasing the Current limit setting and the ACC setting.  Monitor the output current.
