Application
The Q parameters listed below enable you to program basic
mathematical functions in a part program:
 Select a Q parameter function: Press the Q key (in the numerical
keypad at right). The Q parameter functions are displayed in a soft-
key row
 Select the mathematical functions: Press the BASIC ARITHMETIC
soft key. The TNC then displays the following soft keys:
Overview
To the right of the "=" character you can enter the following:
 Two numbers
 Two Q parameters
 A number and a Q parameter
The Q parameters and numerical values in the equations can be
entered with positive or negative signs.
