Abstract
The invention is based on a method for determining the remaining running time of an electric drive mechanism until a mechanical limit stop has been reached, wherein surfaces to be closed are moved into mechanically limited end positions by means of the drive mechanism. After the position of the surface to be closed is detected relative to a mechanical limit stop, the time difference between two incremental pulse generators 25 near the limit stop is determined, and the remaining running time 26 of the electric drive mechanism until the mechanical limit stop is reached is calculated.
