Siemens A33422 fault code meaning

Series: G130-G150

Encoder 3: Square-wave encoder pulse count outside tolerance

converter

Meaning: The measured zero pulse distance does not match the set zero pulse distance. If square-wave encoder pulse count correction is enabled and fault 31131 has been reconfigured, this alarm is triggered when the accumulator value is greater than p4683 or p4684. Set the zero pulse distance for zero pulse monitoring in p0425 (rotary encoder).

Series: G210

Encoder 3: Square-wave encoder pulse count outside tolerance

converter

Meaning: The measured zero-pulse spacing does not match the set zero-pulse spacing. When square-wave encoder pulse count correction is enabled and fault 31131 has been reset, this alarm is triggered if the accumulator value is greater than p4683 or p4684. Set the zero-pulse spacing for zero-pulse monitoring in p0425 (rotary encoder).
