Application
This MOD function determines whether the coordinates are displayed
in millimeters (metric system) or inches.
To select the metric system (e.g. X = 15.789 mm), set the Change
mm/inches function to mm. The value is displayed to 3 decimal
places.
To select the inch system (e.g. X = 0.6216 inches), set the Change
mm/inches function to inches. The value is displayed to 4 decimal
places.
If you would like to activate the inch display, the TNC shows the feed
rate in inch/min. In an inch program you must enter the feed rate larger
by a factor of 10.
