Speed error

What does 61 mean?

The actual motor speed is significantly different from the reference speed, indicating a control deviation. This can be caused by encoder connection issues or, in the case of a PMS motor, by exceeding its pull-out torque. An uncorrected speed error can lead to process instability or drive protection trips.

Complete Troubleshooting Guide

1. 1

   Check the encoder connection for tightness, correct wiring, and signal integrity.

2. 2

   For PMS motors, evaluate if the motor load is consistently exceeding its pull-out torque and adjust the load or motor sizing accordingly.
