Full color printing machine systems

The primary goal of first upgrades are carried out in 2003, and it was added three full-colour units, as well as an additional folding machine. To replace the legacy DC drive system, Rockwell Automation designed and implements an AC drive system incorporates five new speed induction motors specially designed to provide continuous torque down to very low speeds. The main safety problem introduced by the project related to the numerous combination of clutch configurations which are manually set and entered into the control and drive system. Control system keeps track of which printing units are clutched together and allocate the required number of drives, including master drive. During plating up, it's essential for operators safety that each print unit's movement is limited to locally controlled inching functions.
