摘要
针对PLC数模混合变频调速控制系统的可靠性受环境影响大、成本高、维护周期长等缺点,设计了一种远程通信变频调速的PLC 控制系统.采用Modbus RTU 通讯协议、RS485 通信方式、PLC及触控屏实现交流电机的精准连续调速,实时获取变频器和电机的工作状态与故障情况.实验结果表明,该设计是一种调速精度高、易于扩展的变频调速控制系统.
Abstract
To the shortcomings of the digital analog hybrid frequency control system based on PLC such as greatly affected by the environment,high cost,and long maintenance cycle.A remote communi-cation frequency regulation through PLC is designed.The Modbus RTU protocol,RS485,PLC and touch screen are used to realized accurately continuous speed regulation in AC machine,getting the real-time information of its running states and fault conditions.The experimental results show that it can improve precision and expand easily.
