Design of PLC control system in automatic fins-puncher

Fins-puncher was regarded as the subject,PLC was used as the primary control unit of the control system.Synchronous control of conversion frequency was realized adopting the function memory of PLC to control transducer;wherefore the programming was simple,and the control was convenient.Automatic control of the tension of open-book mechanism was realized using tension controller of model ZK-3 and PLC,so the control was convenient,and the disadvantages of the frequency changer controlled by D/A switch were changed.In adition,the automatic control of fins-puncher was realized adapting the technology of touch screen and so on.
