Preassigned Q parameters

For example, the control assigns the following values to the Q parameters Q100 to Q199:

  • Values from the PLC
  • Tool and spindle data
  • Data on operating status
  • Measurement results from touch-probe cycles

The control saves the values of the Q parameters Q108 and Q114 to Q117 in the unit of measure used by the active NC program.

Values from the PLC: Q100 to Q107

The control assigns values from the PLC to the Q parameters Q100 to Q107.

Active tool radius: Q108

The control assigns the value of the active tool radius to the Q parameter Q108.

The active tool radius is calculated from the following values:

  • Tool radius R from the tool table
  • Delta value DR from the tool table
  • Delta value DR from the NC program, if a compensation table or tool call is used
 
Tip

The control will remember the active tool radius even after a restart of the control.
