Special Features Of Rotary Axes - Siemens SINUMERIK 840D sl Function Manual

If a value of 0 is entered in the setting data, the following axial machine data acts as JOG
velocity for the rotary axis:

Special features of rotary axes

Software limit switch
The software limit switches and working-area limitations are active and are required for swivel
axes with a limited operating range. However, in the case of continuously rotating rotary axes
(MD30310 $MA_ROT_IS_MODULO = 1), the software limit switches and working area
limitations can be deactivated for individual axes.
A modulo rotary axis with/without working-area limitation can be used.

Mirroring of rotary axes
Mirroring can be implemented for rotary axes by programming MIRROR(C) or AMIRROR(C).
