Overcurrent

What does -OCF mean?

This fault indicates that the drive controller has detected excessive current flowing to the motor. This can be caused by the motor accelerating too quickly, the drive or motor being undersized for the mechanical load, or a physical blockage preventing the motor from turning freely. Leaving this unresolved can damage the motor, drive controller, or connected machinery due to overheating or mechanical stress.

Complete Troubleshooting Guide

1. 1

   Review and adjust acceleration/deceleration ramp times in the drive controller programming to ensure smooth operation, preventing sudden current spikes.

2. 2

   Verify the motor and drive controller are appropriately sized for the application's mechanical load. Consider upgrading components if they are consistently operating at their limits.

3. 3

   Inspect the mechanical system for any blockages, binding, or excessive friction that could impede motor rotation and clear them.
