Abstract
A method is proposed for positioning a part that is moveable by a drive back and forth between two end positions. For a predefined number of approaches toward one of the end positions, the drive is stopped before reaching this end position and its direction of rotation is changed, and during a subsequent approach toward the end position, the end position is reached, detected and stored for the purpose of normalization, the predefined number being generated in a control unit as random number.

A method for positioning a part that is moveable by a drive back and forth between two end positions, comprising the steps of:
- generating in a control unit a predefined number as a random number;
- for a quantity of approaches toward one of the end positions and corresponding to the predefined number, stopping the drive before reaching the one of the end positions;
- and
- during a subsequent approach toward the one of the end positions, performing the steps of:
- reaching the one of the end positions,
- detecting the one of the end positions, and
- storing the one of the end positions, wherein the reaching step, the detecting step, and the storing step are performed for the purpose of a normalization.
A device for positioning a part that is moveable by a drive back and forth between two end positions, comprising:
- a control unit for generating a predefined number as a random number;
- a drive stopper for stopping the drive before reaching the one of the end positions for a quantity of approaches toward one of the end positions and corresponding to the predefined number;
- and
- a normalization device for controlling the drive such that the part is moved into the one of the end positions, detecting the one of the end positions, and storing the one of the end positions during a subsequent approach toward the one of the end positions, wherein the reaching, the detecting, and the storing are performed for the purpose of a normalization.
