Abstract
In a method for operating an electromechanical adjusting device, having an actuating part driven by a controller controlled motor, and which can be adjusted according to a manual specification for a controller operating element between a first and a second end position, the controller detects the precise position of a blockage of an adjusting movement from fed sensor signals, wherein user action performed on the operating element adjusts the actuating part by a first movement directed toward the end position to a position at which mechanical blockage occurs in order to determine a reference position, and adjusts the actuating part by a second movement into the second end position to examine the validity of the previously determined reference position by a test program which decides whether an automatic operating mode, in which an actuating process runs automatically, is activated, or blocked, as a function of the test result.
