Abstract

A method for generating nominal position values for a position control loop of a numerically continuous-path controlled machine. The method includes presetting nominal position values with a defined interpolator clock rate, digitally filtering the preset nominal position values and transmitting the digitally filtered nominal position values to a position control loop, which with them controls motion of a machine on a path curve at a defined position control clock rate. Adjusting the digitally filtering nominal position values as a function of dynamic characteristics of the machine and adjusting an interpolator clock rate as a function of the dynamic characteristics of the machine.
