Coordinate transformations (frames)
12.4 Programmable rotation (ROT, AROT, RPL)
Further information
Rotation in the plane
The coordinate system is rotated:
• in the plane selected with G17 to G19.
Substitute operation ROT RPL=... or additive operation AROT RPL=...
• in the current plane around the angle of rotation programmed with RPL=....
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: ROT (without axis parameter)
CAUTION
All frame components of the previously programmed frame are reset.
