Application
The Q parameters listed below enable you to program basic
mathematical functions in a part program:
U 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
U To select the mathematical functions, press the BASIC
ARITHMETIC soft key. The TNC then displays the following soft
