TheoperationsequenceofthismachineiscontrolledbythefinishercontrollerPWB,which
uses the 16bit CPU for sequence control. It also performs communication between the
machinebodyandtheoptionalpunchunit.
TheCPUonthefinishercontrollerPWBisprovidedwithaROMwhichstorestheoperation
sequenceprogram.
The finisher controller PWB drives the motors, the clutches and the solenoids according
to the various commands sent from the machine body via the communication cable. In
addition, it notifies information on the sensors and switches to the machine body via the
communicationcable.
