ABSTRACT:
A method for the adjustment of a disk cam, whereby an electric motor turns the disk cam out of a prescribed initial position by a prescribed rotational angle, comprising the steps of providing a disk cam having two markings in a prescribed angle from one another defining a target sector; sensing said two markings during the rotational motion of the disk cam by a sensor stationarily arranged outside the disk cam; in the initial position of the disk cam arranging the sensor having an angular spacing from a target radius of the target sector in rotational direction that is aligned to the rotational angle; identifying the running time of the passage of the markings at the sensor; and arresting the motor in response to the sensing of the second marking and supplying the motor with electrical energy for turning it in the opposite rotational sense, the amount of this energy dependent on the respectively identified running time, being taken from an energy/running time characteristic for the return of the disk cam to the initial position.
