Abstract: The present invention relates to establishing a rotational speed-dependent safe operating mode. For this purpose, two redundant control paths are provided and are each designed to establish either an active short-circuit or a freewheeling mode as the safe operating mode. In this way, even if one control path fails, a rotational speed-dependent safe operating mode can still be fully established.

Differences in the fluctuations of the supply voltages that are supplied to the sensor unit and the signal detecting unit essentially result in the generation of undesirable fluctuations in the measurement signal. To minimize these effects or compensate for them, the digitized measurement signal is corrected In response to a voltage signal (U) that represents the imprecision x1 of the first supply voltage (VS1).
