摘要
针对变频器通信应用,介绍了MODBUS协议的特点及其组成;设计了RS485电路接口;并以ARM Cortex-M3微控制器为核心,设计了MODBUS协议的实现方案。针对变频器F2000-G开发了嵌入式系统,实现变频调速功能,应用于无损检测试验仪。
The MODBUS protocol and its composition are introduced with the application of inverter communication.The circuit interface of RS485 is given and the execution program of MODBUS protocol is given based on ARM Cotex-M3 MCU.The embedded system for F2000-G is developed to control the AC motor for its use in NDT experiment apparatus.
