Title:
METHOD FOR MOVING AN ELEMENT, WHICH IS DRIVEN BY AN ELECTRIC MOTOR INSIDE A PREDETERMINED MOVEMENT SECTION BETWEEN TWO BLOCK POSITIONS EACH FORMED AS A LIMIT STOP, INTO A BLOCK POSITION
Document Type and Number:
WIPO Patent Application WO/2011/144634
Kind Code:
A3
Abstract:
The invention relates to a method for moving an element, which is driven by an electric motor inside a predetermined movement section between two block positions each formed as a limit stop, into a block position, characterized in that, when moving the driven element into at least one of the two block positions, the motor current of the electric motor is continuously reduced over a preset period to zero after reaching the mechanically defined block position by the pulse width-modulated switching of the supply voltage of the electric motor at a decreasing pulse-pause ratio.
