Encoder fault

What does 43 mean?

A problem has been detected in the encoder signals, which are crucial for speed and position control. Subcodes in T.14 provide specifics like missing channels A (S1) or B (S2), both channels missing (S3), reversed encoder (S4), missing encoder board (S5), serial communication fault (S6), channel A/B mismatch (S7), resolver/motor pole pair mismatch (S8), or missed start angle (S9). This can lead to loss of accurate motor control.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Ensure the encoder wiring shield is properly grounded to prevent electrical noise and signal interference.
