(Note 1) Inch/metric conversion is performed in either of 2 ways: conversion from the parameter
screen ("#1041 I_inch: valid only when the power is switched on) and conversion using
the G command (G20 or G21).
However, when a G command is used for the conversion, the conversion applies only to
the input command units and not to the input setting units.
Consequently, the tool offset amounts and other compensation amounts as well as the
variable data should be preset to correspond to inches or millimeters.
(Note 2) The millimeter and inch systems cannot be used together.
(Note 3) During circular interpolation on an axis where the input command units are different, the
center command (I, J, K) and the radius command (R) can be designated by the input
setting units. (Use a decimal point to avoid confusion.)
