Abstract
A method for control of a drive for a tool or workpiece uses pilot control and a device with a control apparatus, the pilot control taking place depending on a frequency of movement which corresponds to a reference variable. In this way, a contouring error can be advantageously reduced.

A method for controlling of a drive for a tool or workpiece, comprising the steps of:
- performing pilot control of the drive depending on a frequency of movement which corresponds to a reference variable,
- determining or computing one of the frequency of the reference variable and a characteristic corresponding to the reference variable as the frequency of movement,
- determining at least one pilot factor depending on the frequency of movement, and
- using the at least one pilot factor determined for pilot control.
