Encoder 1

What does 7381 mean?

A feedback fault has occurred with Encoder 1. This can manifest during initial setup due to incorrect wiring, or after sustained operation due to damage, electromagnetic interference, or module failure. It results in a loss of accurate motor position/speed data, which is critical for precise motor control.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Check the encoder interface module (FEN-xx) for damage, loose connections, or proper installation.

2. 4

   Verify proper earthing to mitigate disturbances in communication between the encoder interface module and the encoder.

3. 5

   Consult parameter groups 90 Feedback selection, 91 Encoder module settings, and 92 Encoder 1 configuration for correct settings, and check the event log for auxiliary codes for more detail.
