12.3 Preassigned Q Parameters
The Q parameters 0100 to 0113 are assigned values by the TNC. Such
values include:
l
Values from the PLC
l
Tool and spindle data
l
Data on operating status, etc.
Values from the PLC: QIOO to Q107
The TNC uses the parameters 0100 to Q107 to transfer values from the
PLC to an NC program.
Tool radius: Q108
The radius of the current tool is assigned to 0108.
Tool axis: Q109
The value of parameter 0109 depends on the current tool axis.
No tool axis defined
Z axis
0109 = -1
0109 = 2
Y axis Q109 = 1
X axis 0109 = 0
Spindle status: 01 IO
The value of Ql 10 depends on the M function last programmed for the
spindle.
M function Perameter value
No spindle status defined QIIO = -1
M03: Spindle ON, clockwise 0110 = 0
M04: Spindle ON, counterclockwise QIIO = 1
MO5 after MO3 QIIO = 2
MO5 after MO4
0110 = 3
Coolant on/off: Qll 1
tVl function Parameter value
M08: Coolant on 0111 = 1
M09: Coolant off 0111 = 0
