Help Needed! Mitsubishi QA20 in metric units

[emiliano123]

How do i change machine units from metric to inch for a QA20 Mitsubishi EDM?

It started in metric units after a system restore, a walk through available manuals produce no parameter number to change.

Please Help.

Try entering G20.

Thanks for your reply Awerby.

I'll do that, but will it change only for the program running or about to run.
Or am I mistaken?

Have a nice weekend.

G20 code did not work but the following procedure did:

E-stop the machine, but not tun it off.
goto maintenance/switches/switch screen 2
select INCH from the top left, optionaly elect X0.1 to get 5 decimal precision.
turn machine off with red off button, wait until it fully shuts down.
turn it back on with green button and you will see it working on inch units.

Good Day.
