如题:有台加工中心810004、2000PLC频繁启动不成功,求解,问题持续有1年,需不断启动、热复位、拔插NCU主板来解决问题,隔几天便会出现,时间不定,有时长有时短,请各位大侠给予指导。
下面为部分诊断记录:*****更多的记录我已将Diagnose-2016-5-18.TXT伪装成了JPG格式上传,烦下载后修改后缀成TXT查看,谢谢!

最佳答案
楼主的问题我在利用西门子840D系统改造数控外圆磨床时遇到过,按照以下四步骤解决:
1.多看少动,全清NC、PLC复位后即可进行数据回装,注意,NC与plc数据的格式均为*.arc,可以先装NC再装plc,如果在安装过程中出现询问,不要管,只要按下屏幕上的软键”YES“,确认即可。如仍然无法正常安装,继续下一步,
2.检查MMC单元的连接是否正常可靠,你可以打开操作箱单元,检查MMC单元的各个电缆如MPI、Profibus-dp的连接是否可靠,注意各个插座上的接线做好标记,以防插错,
3.检查NCK备份电池,重新更换后再试机,
4.如以上未凑效,更换NCU-BOX单元,再试机, \\这个是重点检查项目,因为根据现象:
不断启动、热复位、拔插NCU主板;
5.如果故障未变,更换NCU单元,再试机,
一般来说,按照以上方法,即可快速确定故障原因,祝好运!
