西门子PLCS7-300在基于SINUMERIK840D系统的全数控凸轮轴磨床保护中的应用

Application of Siemens PLC S7-300 based on the SINUMERIK 840D CNC cam grind protection

本文介绍了在采用SINUMERIK840D系统的全数控凸轮轴磨床中,应用PLCS7-300通过NC变量选择器读取NCK中数据,并对数据进行判断处理以实现手动(JOG)状态下操作的保护。

This paper introduces the utilization of NC Variable Selector in SINUMERIK 840D based on CNC cam grind to read the data in NCK, and by estimation and processing the data to achieve the aim of protecting the machine in JOG mode.
