摘要
针对传统的变频器模拟控制存在的问题，提出了以ＲＳ－４８５串行接口为基础的数字控制方案，具体分析了串行数字控制中应注意的问题及解决办法，并与总线结构做了比较说明．
The traditional analog control of inverter has the problem of stability andprecision, this artical offered a digital control solution based on RS-485 interface.In thisartical the problem that should be noticed in serial communication is analysed, and thedigital control solution is compared with bus interface.
