More Information
Summary:The arrangement has a gear for motor adjustment of a closure element (1). A drive controller has a path measuring instrument for determining rough position of the element. The instrument has a sensor that produces periodic sensor signals during motor adjustment and supplies periodic counting events to a position counter. The occurrence of a counting event in the counter causes increment or decrement in counting steps based on adjustment direction. A path measuring instrument for determining fine position has a time measuring unit for measuring actual time interval of counting event.
