I am repairing Kirloskar internal grinding machine with Fanuc OT control. Factory in which i am working got this machine about 5 years ago, but noone has worked on it because one axes was not moving. I repared axes about week ago. Now machine returns to zero position, works in JOG and MPG modes, both spindles ir turning. But problem is that i cant make it work in MDI mode. This is first time i am working with Fanuc controls, maybe i just dont now how exactly to work with machine? Example: i turn on the machine, retun axes to zero position, swich to MDI mode. I press M43, then INPUT and then CYCLE START. CYCLE START led blinks, but nothing happens. Documentation says that in this moment grinder work spindle must turn in low speed. There may be problems with parameters too. Maybe someone had similar problems?
About machine:
Kirloskar S-CNC internal grinder MK-IG-1250
Fanuc OTE control.
It is important to repair this machine as fast as i can but about this problem now i have no ideas...
