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.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

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