Method and circuitry for producing nominal position values for a closed loop position control of a numerically continuous-path controlled machine

A circuit arrangement for generating nominal position values for a position control loop of a numerically continuous-path controlled machine, comprising:

• an interpolator unit for presetting nominal position values with a defined interpolator clock rate;
• a nominal position value filter for digital filtration of said nominal position values preset by said interpolator unit;
• a position control loop, which processes said digitally filtered nominal position values in such a way that by way of them a motion of a machine on a path curve is controllable at a defined position control clock rate, wherein along with said nominal position value filter, said interpolator clock rate is also adjusted as a function of dynamic characteristics of said machine.
