Position display for
rotary axes and PLC
auxiliary axes
6 – 232
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 7 7 7
Select the display mode with MP810.x.
7 7 7 7
Activate or deactivate the software limit switches with MP812.
Rotary axes with modulo display can be positioned either without crossing
zero or always along the shortest path:
7 7 7 7
Select the type of positioning with MP7682.
• For bit 2 = 0: Programming with M126
• For bit 2 = 1: You need not program with M126.
