Overcurrent

What does OCF mean?

This fault indicates an overcurrent condition in the drive controller, often caused by a ramp that is too short, excessive inertia or load, or a mechanical obstruction affecting the motor. If unresolved, this can lead to severe damage to the motor or the drive's power components.

Complete Troubleshooting Guide

1. 1

   Review and adjust the drive's acceleration/deceleration ramp settings to a longer duration if the application allows.

2. 2

   Verify the sizing of the motor, drive controller, and mechanical load to ensure they are compatible and not exceeding operational limits.

3. 3

   Inspect the mechanical system for any binding, seizing, or blockages that could cause the motor to draw excessive current.
