408 10 Programming: Q Parameters
10.10 Preassigned Q Parameters
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:
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
