F07562 fault in siemens 6RA80 DC Drive indicate that the Position tracking, incremental encoder not possible. This means the requested position tracking for incremental encoders is not supported.

1. Check the encoder parameterization (p0400, p0404).
2. Use a Control Unit with sufficient NVRAM.
3. If required, de-select position tracking for the incremental encoder (p0411.3 = 0).
