Rotary Axes (R2)

19.1 General
Properties of a rotary axis
Rotary axes are always programmed in degrees. They are generally characterized by the
fact that they assume the same position after exactly one rotation (modulo 360 degrees).
Depending on the application in question, the traversing range of the rotary axis can be
limited to less than 360 degrees (e.g. on swiveling axes for tool holders) or may be unlimited
(e.g. when the tool or workpiece is rotated).
Definition of a rotary axis
An axis is declared as rotary axis with the aid of MD30300 IS_ROT_AX = 1.
Note
The geometry axes (X, Y, Z) cannot be used as rotary axes or spindle. MD20050
AXCONF_GEOAX_ASSIGN_TAB (assignment of geometry axis - channel axis) defines
these geometry axes.

For axes / rotary axes, the extended addressing (e.g. C2=) or an axis name can also be
defined via configuration in the following machine data:
MD10000 AXCONF_MACHAX_NAME_TAB or
MD20080 AXCONF_CHANAX_NAME_TAB.
