Abstract
A method for controlling the movement of axles whose drives are connected for exchanging energy, in particular by connecting intermediate circuits of the converters respectively comprised by the drives, prior to the start of the movement, a predictive determination of the sequence of movements being performed, in the process of which first the time-critical axle is determined, then the travel profile of the time-critical axle is defined, then a respective total energy consumption is assigned to the possible travel profiles of additional axles, from these, the profile is selected that has the smallest total energy requirement associated with it, and then the movement is carried out.
