Siemens F07996 fault code meaning

Series: S220

Drive: Magnetic pole position detection not performed

converter

Meaning: The operating mode was changed during operation. This change requires pole position detection, which cannot be performed in the current state: - The drive switches directly from operation without an encoder to operation with an encoder, without prior pole position detection for the encoder. The value of p1404 is between zero and maximum speed, but pulses were enabled in the speed range beyond p1404 without prior pole position detection during operation with an encoder. - An encoder EDS changeover was performed during operation, requiring pole position detection. However, detection cannot be performed (p1982 = 1 or 2, and r1992.7 = 0).
