Programming Qparameters | Preassigned Q parameters
Tool axis: Q109
The value of the parameter Q109 depends on the current tool axis:
Parameter Tool axis
Q109 = –1 No tool axis defined
Q109 = 0 X axis
Q109 = 1 Y axis
Q109 = 2 Z axis
Q109 = 6 U axis
Q109 = 7 V axis
Q109 = 8 W axis
Spindle status: Q110
The value of the parameter Q110 depends on the M function last
programmed for the spindle.
Parameter M function
Q110 = –1 No spindle status defined
Q110 = 0 M3: Spindle ON, clockwise
Q110 = 1 M4: Spindle ON, counterclockwise
Q110 = 2 M5 after M3
Q110 = 3 M5 after M4
Coolant on/off: Q111
Parameter M function
Q111 = 1 M8: Coolant ON
Q111 = 0 M9: Coolant OFF
Overlap factor: Q112
The control assigns Q112 to the overlap factor for pocket milling.
Unit of measurement for dimensions in the NC program:
Q113
During nesting with PGM CALL, the value of the parameter Q113
depends on the dimensional data of the NC program from which the
other NC programs are called.
Parameter Dimensional data of the main program
Q113 = 0 Metric system (mm)
Q113 = 1 Imperial system (inch)
