Calling Q parameter functions

When you are writing an NC program, press the Q key (in the
numeric keypad for numerical input and axis selection, below the +/-
key). The control then displays the following soft keys:
Soft key 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 directly
Function for machining
complex contours
If you define or assign a Q parameter, then the control
shows the Q, QL and QR soft keys. You can use these
soft keys to select the desired parameter type. Then you
define the parameter number.
If you have a alphabetic keyboard connected via the
USB port, you can press the Q key to open the dialog for
entering a formula.
