【正文】 king 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. KEY WORDS: Paper machine, Speed chain, Division drive, Load distribution III 目 錄 摘 要 ...................................................................................................................................
