• Coolant is turned o (like M09)
No more lines of code in the le are executed aer the M02 or M30 command is executed. Pressing
Cycle Start starts the program back at the beginning of the le.
7.5.2 Spindle Control – M03, M05
To start the spindle turning clockwise (forward) at the currently programmed speed, program: M03
The speed is programmed by the S word.
To stop the spindle from turning, program: M05
It is OK to use M03 if the spindle speed is set to zero; if this is done (or if the speed override switch is
enabled and set to zero), the spindle won’t start turning. If later the spindle speed is set above zero
(or the override switch is turned up), the spindle starts turning. It is permied to use M03 when the
spindle is already turning or to use M05 when the spindle is already stopped.
7.5.3 Tool Change – M06
To execute a tool change sequence, program: M06
M06 behaves dierently depending on whether or not a mill is equipped with an ATC (automac
tool changer).
Mill is not equipped with an ATC:
M06 commands the mill, stops the spindle, pauses program
execuon, and prompts operator to change tools by ashing Tool
Change LED.
The program resumes aer the operator presses the Cycle Start
buon to conrm that the tool has been changed.
Mill is equipped with an ATC:
If the requested tool (T number) is assigned to the carousel, M06
iniates an automac tool change.
If the tool is not assigned to the carousel, the operator is prompted
to manually change the tool and press Cycle Start to conrm the tool
change. This resumes the program.
You are strongly advised to put the T~, the M06 and the G43 H~ on one line (block) of code. See G43
for more details.
Example: N191 M06 T3 G43 H3
7.5.4 Coolant Control – M07, M08, and M09
To turn coolant on, program: M07
To turn ood coolant on, program: M08
To turn all coolant o, program: M09
