Abstract
A device and method for apportioning a movement of a machine element driven by at least two drives for movement along a drive axis of a machine tool or production machine are described. A low-pass filter filters predetermined desired drive axis values to generate filtered desired drive axis values, with a first controller receiving the filtered desired drive axis values as control input value for controlling a first of the at least two drives. A delay unit with a constant group delay time temporally delays the desired drive axis values and generates delayed desired drive axis values, whereafter a subtracter determines a difference between the filtered desired drive axis values and the delayed desired drive axis values. A second controller receives the determined difference and provides, based on the determined difference, a second control input value for controlling a second of the at least two drives. With these features according to the invention, a movement of a machine element along a drive axis of a machine tool or production machine can be optimally apportioned between two or more drives.
