Abstract
The invention relates to a control method and a control device for the operation of rotationally or linearly driven axes with a position control. This involves determining the difference between the setpoint position value (LS) and actual position value (WI) caused by an additional movement component during the time period of the occurrence of at least one superposed movement by subtraction of one value from the other. Furthermore, it is possible to eliminate movement components which are known, periodic and can be mathematically determined as desired from all the required control data paths during the time period of the superposed movement.
