我厂有一台ZB8216铣端面钻中心孔机床,设计为用传统的继电器J01的一套控制电路同时控制左右刀具同步工作,但由于所采用的液压传动常发生左右液压不同,不能使左右刀具同步而易出现废品.为此,经我们研究后决定采用日本OMKON公司的C20型PC可编程控制器来改造原有控制系统.这种PC的指令逻辑功能比较强、编程简单,而且体积小,价格便宜.其基本型只有16个输入点,12个输出点;可扩展到输入点80点、输出点60点.ZB8216机床需要31个输入
I plant a ZB8216 milling face drilling center hole machine, designed to use a traditional control relay J01 circuit simultaneously control the left and right tools simultaneously, but due to the hydraulic drive often occur around the different hydraulic pressure can not be synchronized around the tool and Therefore, after our study, we decided to use the C20 PC programmable logic controller from Japan OMKON company to transform the original control system.This PC’s instruction logic function is relatively strong, programming is simple, and small size, the price is cheap . Its basic type is only 16 input points, 12 output points; can be extended to the input point 80 points, the output point 60. ZB8216 machine needs 31 inputs
