Abstract: A door drive for garage, garden, hall or factory doors, comprising a motor unit which comprises a drive motor and a motor output shaft, an output transmission, which on the input end can be connected with the motor output shaft and on the output end includes a transmission output shaft for driving a door moving element, in particular a door shaft, a release clutch for releasing the motor output shaft with respect to the door moving element as well as at least one damping element for damping drive shocks. The door drive is characterized in that the output transmission includes a transmission housing formed separate from the motor unit and together with the release clutch and the damping element forms a separate, modular drive attachment, which can be connected on the one hand to the motor unit and on the other hand to the door moving element.

Abstract: The present invention relates to a control system for a door drive with a plurality of components and a digital data bus via which the components communicate, wherein at least one safety component such as a closing edge-safety device or a light barrier detects safety-relevant events and reports the same via the data bus. When detecting a safety-relevant event, the safety component blocks the communication via the data bus for a certain time, wherein the remaining components detect the missing communication on the data bus and interpret the same as notification of a safety-relevant event.

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.
