840dsl出现230021power unit ：ground fault 4105报警

• SIMODRIVE

设备突然出现这个报警 yz公用一个模块，跟另外一个机床模块对调后问题没有转移。后面不知道怎么处理了。尤其是这个4105我感觉很重要但是不知道怎么查了也不会查了。请大神指教

图片说明：

840dsl出现230021power unit ：ground fault 4105报警    840dsl出现230021power unit ：ground fault 4105报警   

最佳答案

最快速的方法 ，你把电机电缆与功率模块脱开后再上电试试，如果还有报警就可能是功率模块问题，如果没有报警你就要检查电机线缆是否破损对地短路，电机三相是否有对地，当然SME或SMC模块也有可能短路，进水、进油、进切削液都有可能，逐个排查。
