In accordance with the invention, the programming unit is configured as an external device, wherein for operation and/or maintenance of the door drive a data transmission connection can be established between the programming unit and the door control.

Abstract: The present invention relates to a door, in particular a sectional door, having a door leaf comprising a plurality of panels which are connected to one another and are guided in guide rails via rollers, with at least the topmost roller pair extending in separate guide rails over a part of its travel path during the opening or closing of the door.

Abstract: The present invention comprises a method for operating a door drive which includes at least one high-speed mode and at least one normal-speed mode, with the following steps: determining a load-dependent operating parameter of the door drive and changing from the high-speed mode into the normal-speed mode in dependence on the load-dependent operating parameter, in order to prevent an overload of the door drive. The invention likewise comprises a corresponding door drive.

Abstract: The present disclosure relates to a sensor unit for the position determination of a powered door having a position sensor and a transmission stage for the connection of the position sensor to the drive shaft of the door, with the sensor unit having its own housing so that it can be installed independently of the drive unit of the door.

Abstract: The present invention relates to an apparatus for a door drive, in particular for roller doors, sectional doors or the like, having a door movement element, in particular a door shaft, for the opening and closing of a door and a connection means arranged at the door movement element. In accordance with the invention, the door drive includes at least two electric motors of which one is indirectly/directly fixedly connected to the connection means arranged at the door movement element and all further electric motors are arranged radially movably around the door movement element and are connected thereto via the arranged connection means.

Abstract: The present disclosure relates to a sensor unit for the position determination of a powered door having a position sensor and a transmission stage for the connection of the position sensor to the drive shaft of the door, with the sensor unit having its own housing so that it can be installed independently of the drive unit of the door.

Abstract: The present disclosure relates to an emergency release for a garage door drive with a sliding latch, wherein the sliding latch is linearly movable by turning a rotary knob.

Abstract: The invention relates to a system to control the motor drive of a garage door panel which is reciprocatingly movable and guided along a predetermined track between two end positions, and possibly, one or more intermediate stop positions, said garage door panel including a switching device which indicates the assumption of the respective end position or stop positions, the output signals of this switching device being usable to switch off the power supply to the drive motor, wherein the limit switches or reference point switches are actuatable through rotatable cams which simulate the garage door path. According to the invention, both the rotating cams as well as the limit switches are combined to form one constructional unit.

Abstract: The invention relates to a gate or door drive housing with a basic carrier body for preference in the shape of a bowl or shell, to which various different drive components can be secured, and a cover hood which can be connected to the basic carrier body. According to the invention, a housing extension for accommodating additional and/or larger drive components can be connected in a releasable manner in an exact fit to the basic carrying body.

Abstract: A drive for closure elements is provided, in particular in the area of garage and industrial doors, but also for example in the form of roller shutters, with a reference value generator arranged in the motor or in the gearing of the drive for determining the actual position of the closure element. When a reference point position is reached, the reference value generator emits a signal or causes a signal modification, on the basis of which the actual-value generator can be calibrated. The reference value generator has two reference discs rotating in different speeds, which, in predetermined angular positions to one another, define the reference point positions which can be scanned by at least one scanning device.

Abstract: A garage door drive includes a housing and at least one light unit. According to the invention, at least one mounting point for the mechanical and electrical connection of the attachably and detachably constructed at least one light unit is arranged on the housing.

Abstract: The invention concerns a drive for closing devices, for example gates or shutters, with variable speed output drive and a device for detecting a given position of the closing device. According to the invention, the drive speed output depends on the position of the gate and can be controlled depending on the given mechanical closing characteristic of the closing device.
