Device and method for synchronizing a plurality of electric drive units in a paper processing machine

A method for synchronizing processes in a paper processing machine, the processes being executed by a plurality of units connected to a central control unit via a data bus, comprising the steps of:

• distributing movement commands by the central control unit via the data bus to the plurality of units, the movement commands containing an instant for executing the movement commands;
• and
• maintaining an absolute time for synchronously executing the movement commands at the instant.

A paper-processing machine comprising:

• a device for synchronizing processes having a central control unit;
• a data bus;
• and a plurality of units being connected to the central control unit via the data bus, wherein the central control unit distributes movement commands via the data bus to the plurality of units, the movement commands including an instant for executing the movement commands, the units maintaining an absolute time to synchronously execute the movement commands at the instant.
