                                                  西门子变频器故障分析和处理方法

一般来说，当遇到西门子变频器故障时，再上电之前首先要用万用表检查一下整流桥和IGBT模块有没有烧，线路板上有没有明显烧损的痕迹。

　　具体方法是：用万用表(好是用模拟表)的电阻1K档，黑表棒接变频器的直流端(-)极，用红表棒分别测量变频器的三相输入端和三相输出端的电阻，其阻值应该在5K-10K之间，三相阻值要一样，输出端的阻值比输入端略小一些，并且没有充放电现象。然后，反过来将红表棒接变频器的直流端( )极，黑表棒分别测量变频器三相输入端和三相输出端的电阻，其阻值应该在5K-10K之间，三相阻值要一样，输出端的阻值比输入端略小一些，并且没有充放电现象。否则，说明模块损坏。这时候不能盲目上电，特别是整流桥损坏或线路板上有明显的烧损痕迹的情况下尤其禁止上电，以免造成更大的损失。

　　如果以上测量西门子变频器故障结果表明模块基本没问题，可以上电观察。

　　1、上电后面板显示[F231]或[F002](MM3变频器)，这种故障一般有两种可能。常见的是由于电源驱动板有问题，也有少部分是因为主控板造成的，可以先换一块主控板试一试，否则问题肯定在电源驱动板部分了。

　　2、上电后面板无显示(MM4变频器)，面板下的指示灯[绿灯不亮，黄灯快闪]，这种现象说明整流和开关电源工作基本正常，问题出在开关电源的某一路不正常(整流二极管击穿或开路，可以用万用表测量开关电源的几路整流二极管，很容易发现问题。换一个相应的整流二极管问题就解决了。这种问题一般是二极管的耐压偏低，电源脉动冲击造成的。

　　3、有时显示[F0022,F0001,A0501]不定(MM4)，敲击机壳或动一动面板和主板时而能正常，一般属于接插件的问题，检查一下各部位接插件。也发现有个别机器是因为线路板上的阻容元件质量问题或焊接不良所致。

　　4、上电后显示[-----](MM4)，一般是主控板问题。多数情况下换一块主控板问题就解决了，一般是因为外围控制线路有强电干扰造成主控板某些元件(如帖片电容、电阻等)损坏所至，或与主控板散热不好也有的关系。但也有个别问题出在电源板上。

　　5、上电后显示正常，一运行即显示过流。[F0001](MM4)[F002](MM3)即使空载也一样，一般这种现象说明IGBT模块损坏或驱动板有问题，需更换IGBT模块并仔细检查驱动部分后才能再次上电，不然可能因为驱动板的问题造成IGBT模块再次损坏！这种问题的出现，一般是因为变频器多次过载或电源电压波动较大(特别是偏低)使得变频器脉动电流过大主控板CPU来不及反映并采取保护措施所造成的。

　　总结以上，大的原器件如IGBT功率模块出问题的比例倒是不多，因为一些低端的简单原器件问题和装配问题引发的故障比例较多，如果有图纸和零件，这些问题便不难解决而且费用不高，否则解决这些问题还是不容易的。简单的办法就是换整块的线路板！
