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
A method for moving a movable element into a block position includes providing a supply voltage to an electric motor associated with the movable element for the motor to generate a motor current and drive the element with motor power dependent on the motor current in order to move the element along a path. Upon the element being moved into a block position of the path, the supply voltage provided to the motor is controlled such that the motor current generated by the motor is continuously reduced over a time period to zero. For instance, the supply voltage is pulse-width modulated at a decreasing pulse duty ratio over the time period such that the motor current generated by the motor is continuously reduced over the time period to zero.
