Hey all,

I am trying to find if any here may have any information as to the wiring and parameters for adding an MPG to a Fanuc 21tb used on a hardinge cobra 42 circa 1998. I have the schematics and it appears it has provisions for the mpg inputs and they are broken out to the operator panel I/0 board and empty there. the wires are there from the Fanuc control side. problem is there isn't any information on what inputs are what and if they are simple point to point connections or floating point. i have attached a condensed version of my machine schematic around the MPG connections. I would simply like to have a handheld mpg to be able to jog switch between x/z axis and select increments without having to go around to the operator panel and button press around the world to achieve this. Any help would be greatly appreciated!
