Position Meaning
Actual values Enter the coordinates of the current tool
position relative to the active coordinate
system.
Reference values Enter the coordinates of the current tool
position relative to the machine datum.
ACTL measured values Enter the coordinates relative to the active
coordinate system of the datum last
probed in the Manual operating mode.
REF measured values Enter the coordinates relative to the
machine datum of the datum last probed in
the Manual operating mode.
With the arrow keys and ENT, select the position that you wish to
confirm. Then press the ALL VALUES soft key so that the TNC saves
the respective coordinates of all active axes in the pallet table. With
the PRESENT VALUE soft key, the TNC saves the coordinates of the
axis on which the highlight in the pallet table is presently located.
If you have not defined a pallet before an NC program,
the programmed coordinates are then referenced to the
machine datum.
