Abstract
The invention relates to a method for controlled braking of an electrically powered lifting action in the event of a failure, such that at least one of the nominal values for 'rotational direction' and/or 'operating speed' and/or “door position” and/or “motor capacity” and/or “motor current” is ascertained and compared with an actual value, and such that a motorized braking process or motorized stopping process is triggered by a departure of the actual value from the nominal value that lies outside a predetermined range. In addition the invention relates to a device for applying said method.
