10.10 Preassigned Q Parameters
The Q parameters Q100 to Q122 are assigned values by the TNC.
These values include:
n
Values from the PLC
n
Tool and spindle data
n
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:
n
Tool radius R (Tool table or TOOL DEF block)
n
Delta value DR from the tool table
n
Delta value DR from the TOOL CALL block
Tool axis: Q109
The value of Q109 depends on the current tool axis:
Spindle status: Q110
The value of Q110 depends on which M function was last
programmed for the spindle:
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
M Function
Parameter value
No spindle status defined
Q110 = –1
M03: Spindle ON, clockwise
Q110 = 0
