今天公司的一台840D系统出现了故障,某个轴无法动作,在点动情况下出现报警代码:25201轴伺服故障;21612轴复位使能,原因3;230021功率单元接地;每次都是一点动就出报警,不点动时界面上无报警信息,自动的时候当运行到该轴的程序时就报警。程序可以在线监控,各个使能信号条件都满足,及时报警信息出现,轴的使能信号还是通的。然后我准备用simotion在线监控,一直连不上,刚开始用的是网线连接,不成功,后来改用PC adapter MPI总线连,还是不成功,在接口设置单元里面也都设置对了。我还以为自己的电脑有问题,拿到别的伺服系统上面可以正常监控。连接时出现的报警信息如下:

Error: SINAMICS_Integrated: Error occurred while establishing a connection to device 'SINAMICS_Integrated'.

刚开始打开simotion软件时还会提示缺少软件安装包,我还特意请教了网上的朋友安装了相应的安装包,现在都已经装成功了,没有在提示下图的信息,可就是在线监控无法实现:

希望论坛上的朋友给点意见,为什么会出现无法在线监控的情况呢?指教一下小弟,谢谢大家了!
