12.6.7 Explanation of the programming and operation of coordinate
transformation
• Fictitious axes must not be programmed in the reset position (G130, G230, G330)
Alarm 2043.
• A transformation may only be activated from the reset position, i.e. transition to a different
transformation is only possible via a previous deselection block.
• Coordinate transformation is selected with:
G131 or G231 or G331
G133 or G233 or G333
G135 or G235 or G335
The selection block must not contain any traversing movements, auxiliary functions etc.
• When transformation is selected, none of the real axes in the transformation grouping must
be programmed Alarm 2043.
• Each selection/deselection of transformations is connected to the function "Clear buffer"
(@714). The @714 need not be programmed as it is automatically initiated by the control.
• Cutter radius compensation and tool nose radius compensation must be cancelled before
activating the transformation (due to @714).
• Only one transformation can be selected at a time in any one channel.
• Transformations which are running parallel in different channels must not refer to the same
axes Alarm 2190.
• The plane definition given in the channel-specific machine data applies for the real system.
When a transformation is selected a plane is set for the fictitious system. The fictitious
plane is defined in the transformation data by assigning the fictitious axes. Deviations from
the base planes can be programmed explicitly via G16. The initial setting of the plane is
defined as G17 (A -A
1F
G17 is automatically set when transformation has been selected. The plane which was
valid before selecting transformation is automatically restored after transformation has been
deselected.
