数控机床现在有很多的控制系统,比如FANUC,三菱或者西门子的数控系统,所以你要学习数控机床中的PLC编程,首先你要确定一个品牌,然后去学习它的PLC编程知识!

西门子数控系统的plc编程知识

从图片上我画红线的地方可以看到,828D的系统中使用的PLC是西门子S7-200系列的PLC,而840D系统中使用的是西门子S7-300系列的PLC! 还可以看到他们用的伺服电机广东快乐十分控制系统是西门子S120的!

  • 万用表测量交流、直流电压,区分火线和零线,就是这么简单
  • 判断空开和漏保的好坏,电笔比万用表还好用,可算长见识了
  • 空开和漏保:A、B、C、D系列有什么区别?跟着老电工长长见识
  • 电线接头一受潮就漏电,电工胶布这样缠,就算泡水里也不会漏电
  • 插座一用电就跳闸,原来是零线共用惹的祸,老电工轻松解决了
