摘要
从龙门铣床控制的需要出发,指出了现有继电器接触器控制存在的问题,设计了新型变频器(SVPWM控制技术)和PLC相结合的控制方法,获得了良好的控制效果,具有结构简单,灵活,可靠,低速转矩大等优点,满足了铣床加工要求.
This paper points out the problem of the relay contact control and provides a control method of combineNew Variable Frequency Device （ SVPWM control ） and PLC based on need of Milling Planer control. The control method has the advantages of simple structure, flexibility, reliability, low speed and great torque. It meets processing requirements.
