自己分析與解決問(wèn)題的能力,同時(shí)也能對(duì)工業(yè)生產(chǎn)中運(yùn)用到的如:電動(dòng)機(jī)、變頻器、 PLC、工控機(jī)、通訊、現(xiàn)場(chǎng)總線、觸摸屏等有更深一步的理解。 關(guān)鍵詞 :造紙機(jī),速度鏈,分部傳動(dòng),負(fù)荷分配 II Based on the S7200 PLC culture paper machine transmission control system hardware design ABSTRACT As the world economic development, pulp and paper industry has bee an important pillar of industrial growth, the international advanced paper machines in the high efficiency, low consumption and direction, which is the market petition. And there are a lot of running the paper machine is at a disadvantage in this respect, it is necessary to upgrade the technological transformation, and for papermaking machinery manufacturers also must catch up, the source from the design to enhance performance. Drive as a core part of the paper machine, the development requirements is to improve the speed and automation. The design of the paper machine drive control system for the culture, with ABB Drives and Siemens PLC control work consisting of paper to plete the electrical control system design, the electric drive control system is PLCbased control of AC frequency control system. Through this project is designed to develop their own analysis and problem solving skills, but also can apply to industrial production, such as: motor, inverter, PLC, industrial puter, munications, field bus, touch screen, which are deeper understanding. Motor Control Methods for a more in depth.
