Rotary encoder and motor speed system design and implementation MCGS based on

电机转速是判定电机运行状态的关键参数。文章提出使用欧姆龙CP1E-NA型PLC的高速计数器功能,采集旋转编码器输出的高速脉冲信号,经过编程处理,从而得到高精度的电机实际转速的方法。并使用安装了MCGS工业组态软件的计算机作为监控设备,可以直观实时显示电机实际转速及响应曲线,为工业现场测量电机转速提供一种切实可行的方案。

Motor speed is a key parameter for determining motor running state. In this paper, proposing the method of the actual high precision motor speed, by acquisition of rotary encoder output high-speed pulse signal, with omron CP1E- NA type PLC high-speed counter function. Using the computer installed MCGS configuration software as a monitoring device, a feasible scheme acquiring real-time display motor speed and response curve intuitively, for industrial field measurement motor speed is provided.
