Abstract
A method for operating a building closure having the shape of an overhead sectional door or of a garage door including at least one spring-loaded counterweight device and an electrical drive device is disclosed. A control unit simultaneously monitors the position of the building closure and a motor current for the drive device. When the building closure is in an open or a closed position, the motor current is reduced and maintained at a level to residually energize the drive device to reliably maintain the building closure in a desired position.
