ABSTRACT:
The present invention relates to an electronic circuit and a method for the monitoring of the driving force of a drive mechanism. To reduce the costs for such a circuit by simple technical circuit measures it is provided that the comparator unit used for monitoring is designed as an analog component, while the set-point adjuster is still integrated into the digital control unit of the drive mechanism. The set points stored in the set-point adjuster are fed to a digital-analog converter in such a manner that an analog reference signal can be generated which can be compared with the analog measuring signal of a power pick-up via the comparator unit.
