align="left">每一个变频电源厂家都会有自己公司的售后服务，在您不知道怎么解决问题的时候可以来电或者我们会给予上门维修的服务。不过我们要明确的知道是哪里出问题了。机器有什么样的异常这样就更便于电话的沟通给予解决的方案。<br /> <br /> 一断：指断开变频电源信号连线；<br /> <br /> 二压：由于变频电源板件虚焊或连接件松动，用手压紧后故障可能会消失；<br /> <br /> 三放：在拆卸变频电源单板或量电阻阻值前要先把电容的电放掉；<br /> <br /> 四看：看变频电源故障现象，看故障原因点，看整块单板和整台机器；<br /> <br /> 五测：测变频电源波形，上工装测单板；<br /> <br /> 六听：听变频电源继电器吸合的声音，电感 变压器 接触器有无啸叫声；<br /> <br /> 七摸：摸变频电源<font face="Arial">IC,MOS</font><font face="宋体">管，变压器是否过热；</font><br /> <br /> 八短：把变频电源某一控制信号短接到另一点；<br /> <br /> 九敲：此办法对判断变频电源继电器是否动作有较好效果；<br /> <br /> 十量：用万用表量怀凝的变频电源器件，虚焊点，连锡点。<br /> </div><div
