??? Fanuc OSP ....Which one ?
( never heard of one )
Okuma OSP 5000M.. is a 5000 series controller for M=milling
it has a closed loop co-ordinate scales on it's axes.
This enables the machine to be turned on... and cycle start---you are off and running cutting parts. it knows where it is at all times. If there happens to be a discrepency, it throws up an A level alarm ( nothing moves-all stop )
PS. you should at least warm up your spindle and bearings. Plus exercise the axis to spread lub, before hitting the GO button to extend the life of the spindle ( lots of $$$$ to do the bearings )
You may have a *.LIB and possibly a "WARM.MIN" file in the control, read them. The LIB file is a library of macros to aide you ( don't sweat if you don't have one ). The warm-up file is exactly that , if you have a faster spec. spindle, it does require a gradual warming up.
If you more info to come your way.
give us a bit more info on it.
