Abstract:
1. A method for displacing a movable part ( 16 ) in a setpoint displacement range ( 60 ) between two end positions ( 62 , 64 ) using a motor-driven drive unit ( 24 ); the displacement position of the part ( 16 ) can be sensed using an electronic unit ( 50 ) of the drive unit ( 24 ) in normal operating mode and in emergency displacement mode, and, during operation in emergency displacement mode, the part ( 16 ) can be displaced manually, wherein an action range ( 68 , 70 ) is located outside the setpoint displacement range ( 60 ) limited by the end positions ( 62 , 64 ) and is defined at at least one end position ( 62 , 64 ) outside of the setpoint displacement range ( 60 ), and wherein the electronic unit ( 50 ) monitors whether the part ( 16 ) enters the action range ( 68 , 70 ), whereupon the electronic unit ( 50 ) at least one of initiates calibration or recalibration of the drive unit ( 24 ) and prevents further displacement in the action range ( 68 , 70 ).
