If the Lathe was a retro fit by an independent R.F. then Mazak have nothing to do with it, you will have to find someone familiar with Mits ladder to re-commission it.
You could try asking Mitsubishi Training or CNC systems div for a sample ladder to start from. If it has a mits operator panel, it may make it easier.
I may have one of my old ladders that I could dig out, but no promises.
The ladder can be entered by hand at the console if necessary.
