Patent ID: 6952087

Claim:
A method of controlling a process of moving at least one movable part ( 2 c ) by means of an electric motor ( 12 ) against at least one end stop ( 26 , 28 ), in which pinching events are detected as a function of a least one operating variable of the motor ( 12 ), and if one of said pinching events is detected, the electric motor ( 12 ) is stopped and/or reversed; wherein electric power triggering the motor at less than a maximum or rated power at start of and during a startup phase ( 52 ), system slack being taken up during said startup phase is controlled, so that said electric power is constant while the system slack is taken up and is less while the system slack is taken up than electric power triggering the motor during a subsequent operating phase in which said at least one movable part is moved to said at least one end stop and so that said electric power increases linearly only after the system slack has been overcome, wherein said subsequent operating phase occurs after said startup phase.
