12.3 Pre-assigned Q Parameters
The Q parameters Q100 to Q113 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.
Tool radius: Q108
The current value of the tool radius is assigned to Q108.
Tool axis: Q109
The value of the Q parameter Q109 depends on the current tool axis.
