01.99 12 Functional Descriptions
12.6.8 Transformation machine data change without warm restart
12.6.9 Transformation machine data change without warm restart
Corresponding data
Machine data
• NC MD 5017 bit 6 Transformation machine data change permitted during active
transformation
• NC MD 5017 bit 7 Transformation machine data change effective without warm restart
General
If angles or offsets of the transformation data record are changed, these values are effective at
the next transformation selection - even without a warm restart.
In order for all required data to be available at the next transformation selection, all internal
data required for the transformation are instantly recalculated after each MD change (MD 730-
809). This is executed parallel to machining thus avoiding loss of machining time.
Functionality is effective on the following transformation types:
2D coordinate rotation and 3D coordinate rotation
Functionality is effective in the following MD area:
MD 730 - MD 809
Caution:
Machine data must be changed in time (approx. 100 ms) before transformation selection. This
can also be achieved by programming @714 before transformation selection.
A machine data change has no effect on active and current transformations.
