HEIDENHAIN TNC 430 PA/M - Position Display for Rotary Axes and PLC Auxiliary Axes

6 – 232 HEIDENHAIN Technical Manual TNC 426, TNC 430
Position display for
rotary axes and PLC
auxiliary axes
For these axes you can define the modulo value for the counting mode (i.e.,
the value after which the axis display returns to zero). Also, you can activate
or deactivate the software limit switches of the traverse ranges:
7
77
7 Select the display mode with MP810.x.
7
77
7 Activate or deactivate the software limit switches with MP812.
Rotary axes with modulo display can be positioned either without crossing
