摘要
化学镀铜生产线电气控制系统主要由西门子S7-200型PLC、汇川MD320变频器、张力传感器、操作系统等组成。给出PLC控制流程图,并对PLC控制系统原理进行说明;通过变频器的接线以及参数设定,阐述变频器在系统中的控制作用;通过张力传感器调节实现生产线调速过程中的张力恒定,从而使其稳定运行。实际使用证明,设计的化学镀铜生产线全变频恒张力电气控制系统能够满足客户的生产要求。
Electric control system for chemical copper plating production line mainly consist of Siemens S7- 200 type PLC,Huichuan MD320 frequency converter,tension sensor,operation system. Give the PLC control flow chart,and illustrate the principle of PLC control system; through connection and parameter setting of the frequency converter,state the control function of frequency converter in the system. Stable tension in the process of production line speed control can be realized through the adjustment of tension sensor,and make it work stably. Actual use shows： full frequency conversion constant tension electric control system for chemical copper plating production line can meet the production requirement of the client.
