11.92 12 Functional Descriptions
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.
