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.

Method for determining the remaining running time of a drive mechanism until a limit stop is reached, wherein surfaces to be closed are moved into mechanical end positions by means of the drive mechanism, characterized in that, after the position of the surfaces to be closed is detected relative to a mechanical limit stop, the time difference between two incremental pulse generators (25) near the mechanical limit stop is determined, and the remaining running time (26) of the electric drive mechanism until the mechanical limit stop is reached is calculated.
Method according to one or more of the preceding claims, characterized in that, after the first determination of the remaining running time (26), the corresponding remaining running time (26) is determined at each new position (25) and can be used as a plausibility check.
Method according to one or more of the preceding claims, characterized in that, after the calculated remaining running time (26) elapses, the drive motor of the closing system is shut down.
