G09 - Exact Stop
G09 causes the axes to decelerate to zero velocity at the end of a block. Since G09 is
non-modal, you must program it in every block that requires the tool to come to a
complete stop.
Default—No
Modal—No
Cancels—None
Cancelled by—None
G20 - Inch Mode (default)
This code sets Inch mode. Program this command in the first block of each part program
that uses inches for the dimension.
Default—Yes
Modal—Yes
Cancels—G21
The default format for Inch mode for different types of blocks is shown in the table
below:
Table 2–6.
Inch Mode formats
Unit Display Mode
G20 does not affect the Unit Display Mode as viewed in the position or offset screens.
The correct units are interpreted from the part program.
G09 is not used in conjunction with G00, G01, G02, or G03
commands.
