1、故障原因

①接线错误；

②电磁干扰；

③机械振动导致的编码器硬件损坏；

④现场环境导致的污染；

2、故障排除

①检查接线并排除错误；

②检查屏蔽是否到位，检查布线是否合理并解决，必要时增加滤波器加以改善；

③检查机械结构，并加以改进；

④检查编码器内部是否受到污染、腐蚀（粉尘、油污等），加强防护；

3、安装及接线标准

①尽量使用原装电缆；

②分离电缆使其尽量远离污染接线,特别是高污染接线；

③尽可能始终使用内部电源。如果使用开关电源,则应使用滤波器，确保电源达到洁净等级；

④始终将公共端接地；

⑤将编码器外壳与机器结构保持绝缘并连接到电缆屏蔽层；

⑥如果无法使编码器绝缘,则可将电缆屏蔽层连接到编码器外壳和驱动器框架上的接地 。
