Abstract

A control device of a processing machine actuates an axle drive of the processing machine commensurate with a reference displacement movement, displacing a mechanical structure of the processing machine accordingly. The control device determines an absolute movement of the mechanical structure in space and therefrom, taking into account the reference displacement movement of the mechanical structure, a compensation movement for a compensating mass damping a vibration of the mechanical structure. Arranged on the mechanical structure is a compensating drive which acts on the compensating mass. The control device actuates the compensating drive in accordance with the compensation movement, displacing the compensating mass relative to the mechanical structure and thereby damping the vibration of the mechanical structure.
