泰州三垦变频器修理中心

    2、开关电源：该系列变频器大量采用了厚膜电路，包括开关电源厚膜电路，驱动部分的厚膜电路。采用厚膜电路多半是出于技术保密上的考虑。由于厚膜电路上所有元器件都已被封装了，所以维修相对较困难。  

    3、E9报警：在J300系列变频器中，我们经常会碰到E9报警，我们可以检查一下三相输入侧电源，J300变频器带有三相输入电压检测，输入电压通过分压电阻送到CPU处理，在缺相和输入电压过低的情况下都有可能出现E9报警。  

    4、--故障：此类故障一般都出现在变频器上电时，此外直流侧欠压也会出现此类故障。 

  5、E30--IGBT故障：SJ300系列变频器还会碰到的一种故障现象就是E30报警。导致E30报警的可能性有几方面:其中主要有功率模块损坏，SJ300系列变频器中小功率采用的是日本富士生产的PIM模块，整流和逆变为一体化的模块，与J300采用的IPM智能化模块又有区别。当然模块的损坏会导致E30报警的出现。
