Command format
Plane section command can be omitted. The plane currently selected is valid when it is omitted.
Relationship between selected plane and αβ.
Rotation angle (R) is specified within the range of -360.000 to 360.0000 programming mode.
The rotation angle in incremental programming mode is determined in reference to the angle after
the previous rotational transformation, and in reference to the α axis when it is the first rotational
transformation.
