 <description><![CDATA[那些都做了！就是降低了变频器的载PWN就可以使用！但还是有干扰呀！设罢后电机就有了杂音了！它们是反比关系的！谢谢大师们的解释！]]></description>

 <description><![CDATA[一个是采用优质的屏蔽线。另一个是做好接地。有条件分开敷设，或者通讯线串钢管并接地。关键看现场情况，记得去年，我碰到过一台设备西门子400+ET200系统，从站中设备厂家用0-10的模拟量输入。用了很多方法，还是有干扰，最后我在输入端加了个3.3UF/50V的电解电容，才解决了干扰问题。]]></description>

 <description><![CDATA[走线分开，还要与电源线分开，屏蔽网在信号输入端连接到地（接地电阻最好小于1欧姆），通讯线也最好用屏蔽线，等等。干扰的问题很复杂，改造起来也很麻烦的！]]></description>
