摘要
PLC是一种新型的工业自动化控制装置,由于具有很高的可靠性和使用灵活性,PLC控制系统正在大量地替代传统的继电-接触控制系统。本文用PLC代替传统继电器,对数控刀片刃磨机床进行了自动化改造,详细介绍了控制系统的设计方案,并给出了相应的电气控制原理图和PLC梯形图程序。
PLC is a new kind of advanced industrial control device,the PLC control systems are replacing the conventional relay contact ones in large quantity because of its excellent reliability and adaptability.In this paper,the design of using a PLC control system in NC blade grinding machine instead of the conventional relay control system is introduced,and the electric control schematic diagram and ladder procedure of PLC are given.
