Group 7 = {M03, M05} spindle turning
Group 8 = {M07, M08, M09} coolant (special case: M07 and M08 may be acve at the same me)
Group 9 = {M48, M49} enable/disable feed and speed override controls
Group 10 =
{operator dened M100 to M199}
Non-modal G-codes
Group 0 = {G04, G10, G28, G30, G53, G92, G92.1, G92.2, G92.3}
7.2.7.6 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 eect. There are default sengs for these modal groups. When the
machining system is turned on or re-inialized, default values are automacally in eect.
Group 1, the rst group on the table is a group of G-codes for moon. One of these is always in
eect. That one is called the current moon mode.
7.3 G-codes
The supported G-codes are shown and described in more detail in this secon. The descripons
contain command examples set in Courier type font.
