| 摘要 |
The present disclosure relates to an apparatus for controlling a door drive comprising a path-measuring apparatus for the sensing of a door position and/or a door drive position and for the emitting of a corresponding door position signal as well as comprising a control device for the control of the door drive in dependence on an absolute value of the door position signal and at least one reference point. In accordance with the present disclosure, the apparatus for controlling a door drive is characterized in that the path-measuring apparatus is made with at least two channels and comprises an absolute value encoder for the emitting of an absolute value signal on a first channel and a reference value encoder for the emitting of a plurality of reference point signals on a second channel, and the control device distinguishes a respective reference point signal from other reference point signals using the associated absolute value signal and controls the door drive starting from a specific reference point.
