Abstract
A method for operating a building closure is disclosed. The building closure may be in the shape of a sectional door or a garage door. The position of the building closure and a motor current of a drive device is monitored by a control apparatus. When the building closure stands still, an electrical drive device arrests the building enclosure by providing an electrically conducting connection between winding of the drive device to ground. The position detection device continues to monitor a signal change such that in response to the signal change, the arresting is suspended and the electrical drive device is at least partially energized.
