Abstract:
1. A drive device for at least one of rotational and translational movement, the drive device comprising a plurality of drives for jointly driving a working machine or for moving a mass and a control device, the plurality of drives comprising: at least one power drive providing power to the working machine or moving mass, and at least one control drive controlling at least one of accuracy and dynamics of the working machine or moving mass, wherein the control device controls both the at least one power drive and the at least one control drive from a common input signal, and wherein the control device provides a difference value between a nominal speed value for the drive device and an actual value of an encoder of the at least one power drive, the difference value is multiplied by a factor and provided to the at least one control drive as a nominal value enabling the at least one control drive to compensate for errors of the at least one power drive.
