    The machine has an encoder for all angle related functions.

    thanks McGuyver...
    This I know... But how it is possible that PLC of each printing tower wrongly count revolution means wrongly detected position of paper sheet which resulting half sheet printing on the first sheet...
    How I can change this? Do you have any parameter list of the PLC which could be changed...
