Method for operating stationary variable element, such as gate, door, sectional door, garage door or overhead door, by drive unit, involves delivering information for positioning of stationary variable element by position detection device

摘要

The method involves providing a controller or regulator, storage and a position detection device, and delivering information for positioning of stationary variable element by position detection device. The information is delivered over entire way of stationary variable element. The positioning information is determined by a reference movement, where the information is stored as reference information. The stored reference information is compared with the current position information during the operation of the stationary variable element. Independent claims are included for the following: (1) a method for operating a drive unit for a stationary variable element; and (2) a drive unit for operating a stationary variable element.
