Zero Overload Fault

What does 49 mean?

This fault occurs when the motor requires an excessively high current while operating at zero hertz (stopped), or if the P38 – [Boost Volts] parameter is set too high. This condition can lead to motor and controller overheating even before motion begins.

Complete Troubleshooting Guide

1. 1

   Reduce the mechanical load on the motor while it is at a standstill.

2. 2

   Decrease the motor dwell time at zero hertz if it is prolonged.

3. 3

   Reduce the value of P38 – [Boost Volts] parameter to an appropriate level to prevent excessive current draw.
