摘要
介绍了无缝140生产线冷床区的工艺流程,系统以6SE70变频器为驱动装置,PLC300为控制核心,根据PROFIBUS协议,实现PLC与6SE70的通讯。在冷床控制系统应用后运行稳定,工作可靠,节电率高,充分满足了生产过程的需要。
For the process of cold bed area in 140 seamless production line, and the 6SE70 converter is the driving device, PLC 300 is the controlling center. According to the agreement PROFIBUS, the communication between the PLC AND 6SE70 is realized. After the cold bed controlling system is applied, the unit operates stably, and reliably, the electricity can be saved highly, and requirement of the production process can be met.
