With the development of computer network technology, The frequency drive system of paper machine also is entering a development period of communications network technology as the core ,the drive system will become part of the workshop DCS system or subsystem. Network and centralized control of computer is becoming a major development trends of the frequency drive system in paper machine. In automation, The frequency drive of paper machine tend to multifunctional and intelligent ,playing a greater role in production process and quality management process .
This dissertation have theory and practice, reseaching the development of the domestic and international paper industry, papermaking machinery and machine drive control system in-depth and analysising the theoretical issues of the paper machine drive control system. Drive System is based on HZ-AC 3000, the majority of components is produced by AB co. for the United States.It is a very good application for the import component assembled in home. The system is based on microprocessor of speed ,torque and tension ring tricyclic automatically adjust control principle, it can adjust the acceleration and deceleration time and the largest / smallest rate of soeed freely in the procedure.It have gained good economic returns in many years of practical application .
