Calling Q parameter functions

When you are writing a part program, press the "Q" key (in the
numeric keypad for numerical input and axis selection, below the
+/– key). The TNC then displays the following soft keys:
Function group
Basic arithmetic (assign, add,
subtract, multiply, divide,
square root)
Trigonometric functions
Function for calculating circles
If/then conditions, jumps
Other functions
Entering formulas in the part
program
Function for machining
complex contours
The TNC shows the soft keys Q, QL and QR when
you are defining or assigning a Q parameter. First
press one of these soft keys to select the desired
type of parameter, and then enter the parameter
number.
If you have a USB keyboard connected, you can
press the Q key to open the dialog for entering a
formula.
