hi everyone..
I am machine-tech person...
I got a problem with Fanuc 11M...
Firstly it was stuck on boot with Bubble memory initialize:Error
I initialized the bubble memory....
It says bubble memory initialize:End
than i have to reenter the parameters...
i entered the No of axis
option parameter 1 to 32 in hexadecimal
everything is okay upto that point...
but when machine boots, it boots okay and then it should show the main screen..
But everything halts and screen shows PC500: Watch Dog Alarm. Motherboard shows E.
1. Problem can be wrong option parameters entered...
but we have a copy of Parameters and i tried to re enter the parameters 3-4 times....
but same alarm comes again and again...
2. Problem can be with motherboard or BMU(Bubble memory Board)
I sent it for repair to 2 local Fanuc card repair specialist
after checking they say everything is fine...
I don't have spare BMU to test...
What should I do now. Please help.
