Siemens F7443 fault code meaning

Series: V90

Reference point coordinates outside the permitted range

servo drive

Meaning: The reference point coordinate received when adjusting the encoder via connector input p2599 is outside half the encoder range and cannot be set as the actual axis position. Fault value (r0949, decimal): Maximum permissible reference point coordinate. See: p2599 (EPOS Reference point coordinate value). For motors with absolute encoders, the maximum permissible encoder range is calculated using the following formulas: For multi-turn encoders: (4096 * p29247) / 2. For single-turn encoders: p29247 / 2
