Abstract: The invention relates to a drive device (1), essentially including a motor (26) and a gearbox (27, 83) and a control system (123), for the automation of a door, preferably a garage door, with a connection (120) to a force transmitting means (46) revolving within the drive track (4) and driven by means of the motor (26), wherein the gearbox (27, 83) includes a worm (29) and is equipped with two opposing motor connectors (57, 58), to which selectively a motor (26) or (28) or simultaneously both motors (26, 28) can be connected, wherein the motors (26, 28) act upon the common worm (79), the rotational movement thereof being transferred onto a worm wheel (100), which directly or indirectly acts like a gearbox onto the force transmitting means (46).

Abstract: A drive unit for a door or a gate includes an electric motor, a detection unit for detecting the position of the door or gate, the detection unit being coupled to the motor and providing an identical pulse sequence with every rotation of the motor, wherein the duration of one pulse in the sequence is different from the duration of the other pulses in the sequence, which are equal. All detected pulses are stored in a non-volatile memory. The drive unit includes an electronic control and regulating circuit including an output stage for the electric motor and at least one memory, in which an operational program is stored providing a programmable learning procedure for an opening and closing movement of the door or gate based on the pulses provided by the detection unit.

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.
