Change position display of inch to mm Yasnac LX

Hello Word.

Can someone help me change the display from inches to millimeters on a Yasnac Lx control (L88404E)
After changing the parameters: 6001 D0 to 0

the position screen appears four decimal digits and the dimensions presented correspond to the indicated movements.
the position screen appears in inches and the tool table with four decimal places and inches.
Can I change this, or does it correspond to the development of the screens?

thanks to everyone.
