 <description><![CDATA[[quote]引用第11楼sjm213于2011-04-06 00:38发表的&nbsp;&nbsp;:
改变M端子的电压即可。在同一组端子上同时接入PNP和NPN的试验楼主有没有兴趣做呢？
[/quote]
同一组端子同时接入NPN和PNP以前我做过，可行，不过前提是使用两组DC24V开关电源，PLC本身有一组，再加一组即可。不知版主是怎样做的，难道版主使用了同一组电源 ..]]></description>

 <description><![CDATA[这个风扇 速度&nbsp;&nbsp;&nbsp;&nbsp;太慢&nbsp;&nbsp;1秒89个脉冲 1分钟5340脉冲&nbsp;&nbsp;由于是A B 相&nbsp;&nbsp;4倍速计数 所以还要除以4&nbsp;&nbsp; 所以才1335转


还有个吹风机 我看里面的风扇转的非常快 


什么时候去试试的呢
