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-turning
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.
