DBX2.2 Delete distancetogo (axisspecific) / spindle reset
Special cases, "Delete distancetogo (axial)"
errors, ....
After the axes have been stopped with "Delete distancetogo" the next program block is prepared
with the new positions. The axes thus follow a different contour to the one originally defined in the
part program after a "Delete distancetogo".
If G90 is programmed in the block after "Delete distancetogo" it is at least possible to approach the
programmed absolute position. On the other hand, with G91, the position originally defined in the
part program is not reached in the following block.
