A method for retracting a driven by an electric motor within a predetermined distance of movement between two positions respectively formed as an end stop block element into a block position

The invention relates to a method for retracting a driven by an electric motor within a predetermined distance of movement between two each formed as an end stop block positions element into a block position, which is characterized in that the mechanically defined during retraction of the driven member in at least one of the two block positions after reaching block position is continuously reduced by pulse-width modulated switching of the supply voltage of the electric motor with a decreasing pulse duty ratio of the motor current of the electric motor over a predetermined time period to zero.
