Electrical drive system with drive unit networks, intercommunication networks and multi-link-controller
First Claim
1. An electrical drive system for the synchronized adjustment of the position, speed or acceleration of a plurality of movable, functional parts of devices and machines, the system comprising:
- (a) a plurality of drive units each connected to one or more of the functional parts for said adjustment under computer assisted control;
(b) a plurality of drive networks, each drive network having a plurality of the drive units as network nodes, each drive network allocated to a group of the functional parts, the nodes of at least one of the drive networks connected together for communication between the nodes;
(c) a plurality of intercommunication networks for synchronizing the drive units of different drive networks, each intercommunication network connecting a node of a drive network with a node of another drive network;
(d) a multi-link controller having a plurality of communication components, each communication component being a node of one of the intercommunication networks for coupling the nodes of the intercommunication network; and
(e) drive synchronisation control unit as nodes of an intercommunication network for an electrical drive system having at least one communication interface and at least one processor that controls it and is provided with the following functional modules;
(i) a master axis module, designed to receive, to generate and/or route data and/or commands for a virtual master axis via the at least one communication interface and(ii) a data distribution module, which is designed for controlling a data and/or command flow via the at least one communication interface with one of the networks, in particular the intercommunication network.

Abstract
An electrical drive system for the synchronized adjustment of rotatable axles or linearly movable functional parts in particular for printing machines, in terms of their position, speed or acceleration. Drive units are controlled using computer assistance and are connected to one or more functional parts for their adjustment. A plurality of drive networks, which each have a plurality of the drive units as network nodes, are allocated to some or a group of the functional parts. Inside at least one of the drive networks, its nodes or drive units are arranged in accordance with the master/slave principle and are respectively connected to one another in a ring structure through communication channels and/or a communication system. At least one node of a drive network is coupled in a ring structure with one node of another drive network, likewise in accordance with the master/slave principle, through inter-communication channels and/or an inter-communication system or network.
