11.3 Preassigned Q Parameters
The Q parameters Q100 to Q113 are assigned values by the TNC. Such
values include:
• Values from the PLC
• Tool and spindle data
• Data on operating status, etc.
Values from the PLC: Q100 to Q107
The TNC uses the parameters Q100 to Q107 to transfer values from the
PLC to an NC program.
Tool radius: Q108
The radius of the current tool is assigned to Q108.
Tool axis: Q109
The value of parameter Q109 depends on the current tool axis.
Tool axis Parameter value
No tool axis defined Q109 = –1
Z axis Q109 = 2
Y axis Q109 = 1
X axis Q109 = 0
Spindle status: Q110
The value of Q110 depends on the M function last programmed for the
spindle.
M function Parameter value
No spindle status defined Q110 = –1
M03: Spindle on clockwise Q110 = 0
M04: Spindle on counterclockwise Q110 = 1
M05 after M03 Q110 = 2
M05 after M04 Q110 = 3
Coolant on/off: Q111
M function Parameter value
M08: Coolant on Q111 = 1
M09: Coolant off Q111 = 0
