10.10 Preassigned Q Parameters
The Q parameters Q100 to Q122 are assigned values by the TNC.
These 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.
Active tool radius: Q108
The active value of the tool radius is assigned to Q108. Q108 is
calculated from:
■
Tool radius R (Tool table or TOOL DEF block)
■
Delta value DR from the tool table
■
Delta value DR from the TOOL CALL block
Tool axis: Q109
The value of Q109 depends on the current tool axis:
Tool axis Parameter value
No tool axis defined Q109 = –1
X axis Q109 = 0
Y axis Q109 = 1
Z axis Q109 = 2
U axis Q109 = 6
V axis Q109 = 7
W axis Q109 = 8
Spindle status: Q110
The value of Q110 depends on which M function was 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
