For Configuration 806 (PMSM): Self-configuration of resolver offset

During first commissioning, the position of the rotor winding of the resolver is adjusted to the rotor
displacement angle of the synchronous motor by adjusting an offset. For operating a PMSM with re-
solver, the offset must be adjusted in order to obtain perfectly true running and a maximum torque.
4.4.1 Carrying out of the self-setup
For self-setup of the resolver offset, a separate setup routine is available.
