Abstract (en)
[origin: WO2020259886A1] The invention relates to a drive for a casement of a window or leaf of a door comprising a housing, an electric motor-driven drive unit for operating the casement or leaf and an electronic control unit for actuating the drive unit. A blocking element can be displaced between a blocking position, in which actuation of the leaf or casement is mechanically prevented by blocking the drive unit, and a release position, in which the drive unit is mechanically released for actuation of the casement or leaf. A locking device in a locking state holds the blocking element in the blocking position and, in an unlocked state, allows displacement of the blocking element from the blocking position into the release position. The locking device can only be adjusted from the locking state to the unlocking state if access authorization is in place. A detector is designed to detect whether the blocking element is occupying the blocking position, the drive being designed such that activation of the drive unit is prevented if the detector detects the blocking position of the blocking element.
