Motor Overload Fault

What does 07 mean?

This fault is triggered by the controller's internal electronic overload protection, signifying that the motor is drawing excessive current for an extended period. An excessive mechanical load is usually the cause. Sustained overload can lead to motor winding damage and premature controller failure.

Complete Troubleshooting Guide

1. 1

   Reduce the mechanical load on the motor until the controller output current is below the limit set by P42 – [Motor Overload Current].

2. 2

   Adjust the P38 – [Boost Select] parameter to a lower value if it is contributing to high current draw at low speeds.

3. 3

   Check motor for mechanical binding or friction.
