12.5 Programmable frame rotations with solid angles (ROTS, AROTS, CROTS)

12.5 Programmable frame rotations with solid angles (ROTS, AROTS,
CROTS)
Function
Orientations in space can be defined by programming frame rotations with solid angles. The
ROTS, AROTS and CROTS commands are available for this purpose. ROTS and AROTS behave
in the same way asROT and AROT.
Syntax
The orientation of a plane in space is defined unambiguously by specifying two solid angles.
Therefore, up to 2 solid angles may be programmed:
• When programming the solid angles X and Y, the new X axis lies in the old Z/X plane.
ROTS X... Y...
AROTS X... Y...
CROTS X... Y...
• When programming the solid angles Z and X, the new Z axis lies in the old Y/Z plane.
ROTS Z... X...
AROTS Z... X...
CROTS Z... X...
• When programming the solid angles Y and Z, the new Y axis lies in the old X/Y plane.
ROTS Y... Z...
AROTS Y... Z...
CROTS Y... Z...
Note
Each frame operation is programmed in a separate NC block.
