Method of bridging partial tightness on movable members

Abstract

A method of bridging partial tightnesses of movable members which are received in guides and are driven by electric drive motors includes controlling of drive motors with a monitoring function, performing an automatic monitoring function automatically, and varying a releasing force inside a tightness region in at least one step.

1 . A method of bridging partial tightnesses of movable members which are received in guides and are driven by electric drive motors, comprising the steps of controlling drive motors with a monitoring function; providing an automatic monitoring function by automatically operating control; and varying a releasing force inside a tightness region in at least one step.  
     
     
         2 . A method as defined in  claim 1 , wherein said varying includes varying the releasing force in a plurality of steps.  
     
     
         3 . A method as defined in  claim 1 , wherein said automatically operating control includes increasing the releasing force at a position of the tightness region.  
     
     
         4 . A method as defined in  claim 1 , wherein said automatically operating control includes changing a rotary speed of the movable member.  
     
     
         5 . A method as defined in  claim 1 , wherein said automatically operating control includes a stepped increase of the releasing force by a first starting routine and a second starting routine.  
     
     
         6 . A method as defined in  claim 1 , wherein said automatically operating control includes providing a closing force limiting.  
     
     
         7 . A method as defined in  claim 1;  and further comprising branding a monitoring for starting and aiming point, after which a predetermined time period is cast out or a rotary speed reverse of electrical drive is provided.  
     
     
         8 . A method as defined in claim  4 ; and further comprising performing said first starting routine and said second starting routine so that when the releasing force is increased until it reaches a set maximum releasing force and a value which overcomes the tightness region is stored in an adaptive storage.  
     
     
         9 . A method as defined in  claim 1;  and further comprising setting back the automatic bridging function when the member to be moved reaches a corresponding closing position.  
     
     
         10 . A method as defined in  claim 1;  and further comprising setting back the automatic bridging function when a stoppage of an electrical drive exceeds a predetermined time period.  
     
     
         11 . A method as defined in  claim 1;  and further comprising setting back the automatic bridging function when an opposite direction of an electrical drive is controlled.
