12.6.7 Explanation of the programming and operation of coordinate transformation

• Transformation must not be selected or deselected within a contour block sequence.

• Block search with calculation to a program part where transformation is active is permitted.

• The automatic block search to a program part where transformation is active is not

permitted.

• PRESET shifts of real axes are ignored in transformation.

• Fictitious axes cannot be traversed with the handwheel. Real axes can only be traversed

with the handwheel when transformation is not active.

• DRF is not possible with fictitious axes.

• DRF is possible with real axes only when a program block is active (not for NC STOP).

• The settable angle of rotation for coordinate system rotation (G54 to G57) must always be

ZERO.

• The programmable angle of rotation for coordinate system rotation (G58, G59) must also

be ZERO when transformation is selected or deselected.
