Siemens A31431 fault code meaning
Siemens / A31431
Series: G120-CU250S-2, G120D
Encoder 1: Incremental/absolute position offset too large
converter
Meaning: A deviation from the incremental position was detected when crossing a zero pulse. Equidistant zero pulses: - The first zero pulse crossed establishes the reference point for all subsequent checks. Subsequent zero pulses are spaced at multiples of n relative to the first zero pulse. Equidistant zero pulses: - The first pair of zero pulses establishes the reference point for all subsequent checks. The distance between subsequent pairs of zero pulses must match the expected distance between the first pair of zero pulses.

Motor encoder: Incremental/absolute position difference too large (alarm
converter
Meaning: A deviation from the incremental position was detected when passing a zero pulse. Equidistant zero pulses: - The first zero pulse passed establishes the reference point for all subsequent checks. Subsequent zero pulses are spaced at multiples of n relative to the first zero pulse. Equidistant zero pulses: - The first pair of zero pulses establishes the reference point for all subsequent checks. The distance between subsequent pairs of zero pulses must match the expected distance between the first pair of zero pulses.
