Abstract
The present invention relates to a self-propelled material processing and/or handling system for processing and/or handling construction and/or raw materials, in particular in the form of a mobile crushing system, with at least one working unit, which is drivable, by an electric unit drive, with an electric motor, at least one electric travel drive with an electric motor, as well as a control device to control the electric motors of the unit and travel drives. According to the invention, the control device comprises a common frequency converter for the at least one travel drive and the at least one unit drive and provides various parameter sets for the common frequency converter so that the travel drive is actuatable by the frequency converter on the basis of a first parameter set and the unit drive is actuatable by the common frequency converter on the basis of a second parameter set.
