Abstract:
A method for the acceleration of the adjusting movement in a positioning system comprising:operating at least one stepping motor at a variable control frequency f, the adjusting speed being dependent upon the control frequency f; and initiating a positioning step of the adjusting movement at every period of the control frequency f; the total number of successive positioning steps corresponding to the length of an adjustment area; assigning a determined position within the adjustment area to every positioning step; further including: initially assigning a permissible control frequency fzul to every positioning step; storing the assignment of control frequencies fzul to determined positioning steps as a data record in a storage in such a way that it can be called up; making a comparison, during the operation of the positioning system, for each positioning step between the current control frequency fist and the maximum permissible control frequency fzul assigned to the subsequent positioning step; and increasing the control frequency f for the subsequent positioning step when the result of the comparison is fistzul, the control frequency f for the subsequent positioning step is retained when the result of the comparison is fist=fzul, or the control frequency f for the subsequent positioning step is reduced when the result of the comparison is fist>fzul.
