Modal Groups for G-codes
Group 5 = {G93, G94} feed rate mode
Group 6 = {G20, G21} units
Group 7 = {G40, G41, G42, G41.1, G42.1} cutter radius compensation
Group 8 = {G43, G43.1, G49} tool length offset
Group 10 = {G98, G99} return mode in canned cycles
Group 12 = {G54, G55, G56, G57, G58, G59, G59.1, G59.2, G59.3} coordinate system selection
Group 13 = {G61, G61.1, G64} path control mode
Group 14 = {G96, G97} spindle speed mode
Group 15 = {G07, G08} lathe diameter mode
Modal Groups for M-codes
Group 4 = {M00, M01, M02, M30, M60} stopping
Group 7 = {M03, M04, M05} spindle turning
Group 8 = {M07, M08, M09} coolant (special case: M07 and M08 may be active at the same time)
Group 9 = {M48, M49} enable/disable feed and speed override controls
Group 10 =
{operator dened M100 to M199}
Non-modal G-codes
Group 0 = {G04, G10, G28, G30, G53, G92, G92.1, G92.2, G92.3}
7.4.6 Default Modes
For all G-code modal groups, when a machining system is ready to accept commands, one member
of the modal group must be in eect. There are default sengs for these modal groups. When the
machining system is turned on or re-inialized, default values are automacally in eect.
Group 1, the rst group on the table is a group of G-codes for moon. One of these is always in
eect. That one is called the current moon mode.
7.5 G-codes
The supported G-codes are shown and described in more detail in this secon. The descripons
contain command examples set in Courier type font.
Summary of G-codes
