PROBLEM TO BE SOLVED: To improve versatility by synchronizing the drive controller of a driving system group through a drive bus by a local synchronous clock and by equalizing synchronously the local synchronous clock with a global synchronous clock through a drive data network connecting drive control means. SOLUTION: A driving system of a rotary printing press is equipped with a plurality of driver groups 2, where drivers 4 including motors 5 of every group 2 are controlled through electronic circuits 7 for electric power by drive controllers 6. The drive controllers 6 are connected to a common drive control means 3 connected to a higher-order control unit 9, all drive control means 3 are mutually connected through a drive data network 10. A global synchronous clock is sent by the drive data network 10, synchronizing the driver groups 2 correctly and equalizing the local synchronous clocks of every group 2 with global synchronous clocks by every drive control means 3. |
