For the recommended procedure with respect to scaling machine data, please
refer to Subsection 10.3.3, page 10-285.
The machine data
MD30300: DISPLAY_IS_MODULO (modulo 360 degrees display for rotary
axes)
is used to display the rotary axis position modulo 360 degrees.
The machine data
MD 30310: ROT_IS_MODULO (modulo conversion for rotary axis)
is used to traverse the rotary axis modulo 360 degrees. The limit switches are
not monitored during this process. The rotary axis can thus rotate endlessly.
