安川伺服驱动器在工作中偶尔发出C90故障报警信息。导致安川伺服驱动器维修C90报警原因：①编码器断线或接触不量；②伺服驱动器本身故障；③干扰因素导致；④伺服电机编码器反馈单元故障。 根据以往的伺服器维修经验，绝大多数的情况是是编码器线问题导致，当然了，也不排除是其他原因的，也有伺服电机编码器反馈单元问题造成的，相对概率要小很多。 此次安川伺服驱动器维修的方法是更换一条新的编码器线，暂未见报警出现，还需后续跟踪1至2天。 对安川伺服驱动器换下的编码器线仔细检查，发现中间有一个接头，层层胶布包裹着，一层层慢慢扒开，还是发现了问题，原来这跟线以前这个地方断过，重新接过，线头是没有断了，但是，外层的屏蔽层断了，发生了挺严重的氧化。 是不是因为屏蔽层断了，由于干扰导致伺服驱动器出现偶然发出C90报警？下午重新对该线进行焊接，屏蔽层接上，下次备用。 找到一根佳能扫描仪的数据线，查看一头是迷你USB接口。突发一个想法，试试看能不能和维纶通触摸屏连上。使用MT6070IH软件进行测试，可以没有问题。进过的测试，没有再出现此报警故障了。 至此，此安川伺服驱动器维修故障可以下结论了：伺服驱动器出现偶尔报警C90，是因为伺服编码器线的屏蔽层断开，由于干扰的因素导致的。APPLIED MATERIALS 3320-01104 GSKT EMI SHLDG STRIP 24"L BR
