The invention is directed to a method for the acceleration of the adjusting movement in a positioning system in which at least one stepping motor is controlled at a variable control frequency f, the adjusting speed is dependent upon the control frequency f, and a positioning step of the adjusting movement is initiated at every period of the control frequency f. According to the invention, it is provided in a method of the type mentioned above that a permissible control frequency fzul is initially assigned to every positioning step within an adjustment area 1, the assignments of control frequencies fzul and positioning steps are stored as a data record, and during the adjusting movement a comparison is made for each positioning step between the current control frequency fist and the permissible control frequency fzul of the subsequent positioning step and, depending on the results of this comparison, the control frequency f for the subsequent step is increased when the result of the comparison is fist<fzul, the control frequency f for the subsequent step is maintained when the result of the comparison is fist=fzul, or the control frequency f for the subsequent step is reduced when the result of the comparison is fist>fzul.
