Note
See "Rotation in space" for more information.
Plane change
If you program a change of plane (G17 to G19) after a rotation, the angles of rotation
programmed for the relevant axes are retained and continue to apply in the new working
plane. It is, therefore, advisable to deactivate rotation before a change of plane.
Deactivate rotation
For all axes:
CAUTION
All frame components of the previously programmed frame are reset.
ROT X... Y... Z...
The coordinate system is rotated through the programmed angle around the specified axes.
The center of rotation is provided by the last settable work offset specified (G54 to G57,
G505 to G599).
NOTICE
