Plausibility fault in encoder interface (A3401 = encoder 1 and A3402 = encoder 2)

Was bedeutet F109-44 ?

The encoder interface (A3401 or A3402) does not match the configured data. This suggests a mismatch between the physical encoder type/connection and the drive's settings.

• Encoder data stream indicates a deviation from expected patterns.
• Mismatch in position or velocity feedback from encoder 1 (A3401) or encoder 2 (A3402).
• Faulty encoder communication protocol interpretation.
• Environmental interference corrupting encoder signals.

1. 1

   Check encoder type and configuration (SSI/incremental).

2. 2

   Check the encoder connection/wiring.

3. 3

   Check the polarity of the encoder data.

4. 4

   Check function of the encoder.
