Hi,

I got emco lathe with sinumerik 810T GA3. It was working fine and suddenly it stopped i got nc alarm 2000 ord 1 Emergency stop. I checked PLC alarms you can see it in attached file. I cant figure out what is wrong.

I checked electrical scheme and i didnt find nothing wrong.

i checked manual and i found that i should check ladder diagram for output Q78.1 but i cant find where to check it. I dont have much experiance with sinumerik 810 maybe somebody could help with advices where could be the problem or what else should i check.


Thank you.
