Abstract
A door, especially a sectional door, is operated with the use of a drive unit with a drive gear, a clutch, and a position-detecting unit. The position-detecting unit detects the direction of rotation of the drive gear, detects the number of revolutions of the drive gear by pulses, and stores the pulses, taking the direction of rotation into consideration, in a nonvolatile memory. A data-processing unit is present in which different variable sequence programs are stored, which include not only safety-relevant programs but also a learning program. Reference values are determined by the position-detecting unit for a variable open position of the door, which position can be set as desired, and for a completely open position, which is limited by a stop, as well as for a closed position of the door are stored in a nonvolatile memory and are processed during automatic travel of the door. A door drive consists essentially of a drive unit with a drive gear and a running rail, wherein the drive unit can be moved along the running rail by a motor. The position of the drive unit is detected by a position-detecting unit and stored in a nonvolatile memory, and the drive unit and the drive gear are equipped with a clutch with a status monitor.
