Abstract:
Disclosed is a method for controlling an electrical door drive by means of which the door drive is switched off if the maximum torque is overshot and/or a defined nominal closing rate of the door is undershot as a result of the door drive being obstructed. In order to reliably prevent injuries and damage to people and objects in the event of a functional failure of the safety control system, and in order to nevertheless reliably block or reverse the door, it is proposed that pulse monitoring be carried out on the door drive, for redundant obstruction identification.
