A process for crosslinking a control unit with one or more power units

A process for crosslinking a control unit (R) with one or more power units (L1, L2, L3), wherein a power controller for controlling an electric drive (M1, M2, M3) with power converter valves (8) for producing phase currents for the connected electric actuators and a computing means (7) for generating control signals (10) for the power converter valves (8), and is provided means for Phasenstromistwerterfassung (9) and for digitizing the detected actual current values, having the following method steps: - Composition of the processing power of a driving control to a control unit (R) and the associated power part (L1, L2, L3), - connecting the control unit (R) and each power section (L1, L2, L3) on a real-time digital bidirectional synchronous interface (KOMSYS1, KOMSYS2, KOMSYS3) - transmitting digital Phasenstromistwerten to a superordinate control unit (R) via the interface (KOMSYS1, KOMSYS3, KOMSYS3) and receiving digital voltage setpoints for generating corresponding control signals (10) in the computing means (7) of the superordinate control unit (R) and - synchronization of communication ...
