13. Program Support Functions
(1) The positions of the end point coordinates and skip coordinates are positions in the work
coordinate system.
(2) The end point coordinates, skip coordinates and servo deviation amounts can be read even
during movement. However, it must first be checked that movement has stopped before
reading the machine coordinates and the work coordinates.
(3) The position where the skip signal is turned ON in the G31 block is indicated for the skip
coordinates. The end point position is indicated when the skip signal has not been turned ON.
(For further details, refer to the section on tool length measurement.)
