ABSTRACT:
In order to create a method and an apparatus for anti-trap protection detection for displaceable window and door elements by means of which faster and more stable adjustment to current physical conditions can be achieved during system actuation, in the system the motor (1) is controlled using parameter values generated in real-time using a closed-loop control unit, preferably a PID controller, to keep the speed in the system constant during a learning run and during operational use and to ensure timely trapping detection.
