Motor Overload

What does OLF mean?

This fault signifies that the motor's I²t thermal protection has tripped due to a prolonged overload condition, indicating excessive current draw over an extended period. Sustained motor overload will lead to winding insulation breakdown and permanent motor damage.

Complete Troubleshooting Guide

1. 1

   Review and adjust the motor thermal protection (I²t) settings in the drive controller to accurately match the motor's nameplate data.

2. 2

   Inspect the mechanical load on the motor and reduce it if it consistently exceeds the motor's continuous rating.

3. 3

   Allow the motor to cool down to its normal operating temperature before attempting to restart the system.
