Encoder fault

What does 43 mean?

A problem has been detected in the encoder signals, which are crucial for accurate speed and position feedback. This can be caused by missing or faulty channels (A or B), a reversed encoder, or a missing encoder board. Inaccurate feedback can lead to unstable motor control or drive shutdown.

Complete Troubleshooting Guide

1. 1

   Check all encoder channel connections for tightness and proper wiring.

2. 2

   Inspect the encoder board for proper installation and any signs of damage.

3. 3

   Verify the encoder frequency, especially if operating in open-loop mode, to ensure it is within expected limits.
