Activation
The functions with equidistant indexing for an axis (linear axis, modulo rotary axis or rotary
axis) is activated in the following settings
MD30500 $MA_INDEX_AX_ASSIGN_POS_TAB[axis] = 3
15.5.2 Hirth tooth system
Function
With Hirth tooth systems, positions of rotation on a rotary axis are usually interlocked using a
latch or other toothed wheel via a linear axis. The interlock should only be activated when an
indexing position has been reached precisely. The distance between the indexing positions
is the same (equidistant) across the entire circumference.
