M-code
The following is a list of available M-Codes. Be advised that many
M-codes are machine dependant, and often machine manufacturers
will add, and/or remove some M-Codes.
† Represents supported M-codes.
M-code Description Comment
M* † All other M codes not listed will generate a run-time error.
M0 † Program Stop This command pauses the program. Press GO to resume.
M1 † Optional Program Stop This command pauses the program if the Optional Stop run option
is selected. Press GO to resume.
M2 † Program End This command stops the program after completing of the block.
The cursor moves to the beginning of the program. The current
settings are reset to default values.
M3 † Spindle On (CW)
M4 † Spindle On (CCW)
M5 † Spindle Off
If spindle control hardware is present, the spindle is turned on or
off automatically. If the hardware is not present, the operator is
prompted to turn the spindle on or off.
M6 Tool Change M6 is not necessary. A tool change occurs when the Tool Selec-
tion command is processed.
M7 † Coolant On (Mist)
M8 † Coolant On (Flood)
M9 † Coolant Off
If the AMI hardware is present, the coolant is turned on or off
automatically.
M30 Program End w/ Pallet Shuttle The control does not support control of a pallet changer. This code
has the same effect as M2.
M48 Enable Speed/Feed Override
M49 Disable Speed/Feed Override
It is not possible to disable feed rate override on the control.
These commands are ignored.
M60 Program Stop w/ Pallet Shuttle The control does not support control of a pallet changer. This code
has the same effect as M0.
F † Set Feed Rate The feed rate uses the current program units in effect (ipm or
mmpm). The setting applies to current and subsequent blocks.
The default is determined from the control's configuration setup.
I † Arc center coordinate parallel to
X axis
K † Arc center coordinate parallel to
Z axis
These are the arc center coordinates for G2 and G3 arcs. They are
assumed to be programmed in incremental from the current tool
position.
N † Line Number Line numbering is optional and for readability only. The control
does not make use of this information.
O † Program Number Used at the beginning of a program.
S † Spindle Speed The spindle speed is set to the specified speed (rpm). If the
spindle is currently off (M5), it will not be turned on unless accom-
panied by a spindle direction block (M3 or M4). The setting applies
to current and subsequent spindle direction blocks.
T † Tool Selection This command is used to select the active tool. The tool is speci-
fied by tool number. The tool attributes must be specified in the
Tool table.
