摘要
举例说明了造纸机变频传动中负荷分配产生的原因、造成的影响以及用程序实现负荷分配的设计原理。结合工程实例,重点介绍了造纸机在交流变频传动控制的情况下,用PLC的通讯控制功能和用高性能变频器的直接转矩控制功能实现负荷分配的原理及方法。
This paper Illustrates with examples about the reason, impact and program design principle of load distribution for frequency conversion drive paper machine. Combine the concrete instances with AC frequency conversion drive paper machine in projects , the principle,method of load distribution controlled by PLC＇s communication control function and high-tech frequency converter＇s direct torque control function are also introduced emphatically.
