ABSTRACT:
The invention relates to a method for monitoring and controlling reversing actions in electrically actuatable units, wherein an actuating drive unit can exert an actuating force in order to move an electrically actuatable unit, and a safety circuit automatically switches off the actuating drive unit after a jamming switch-off time that is predetermined for a movement if no movement occurs despite the triggering of the actuating drive unit. According to the invention, a triggered reversing action results in a temporary extension of the predetermined jamming switch-off time from a short jamming switch-off time t1that is predetermined for normal operation to a longer jamming switch-off time t2(2).
