Function
The Q parameters listed below enable you to program basic
mathematical functions in a part program:
 To 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
 To 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
