摘要：
The invention relates to a method and to a circuitry for producing nominal position values for a closed loop position control of a numerically continuous path controlled machine. According to the invention, an interpolator element presets nominal position values with a defined inperpolator clock rate that are digitally filtered in a nominal position value filter that is mounted downstream of the interpolator element. The filtered nominal position values are transmitted to the closed loop position control which controls the movement on a continuous path with a defined position control clock rate. The interpolator clock rate is adjusted on the basis of the dynamic characteristics of the machine in such a manner that the filtered nominal position values that are transmitted by the closed loop position control do not cause any natural vibrations of the machine.
