When the tool offset amount (tool length,
cutter) differs, change it on the tool offset
screen.
An operation error results even if there is one axis
which is not at the restart position for automatic
start (cycle start).

return to the restart position when the cycle is
started.
Machining will restart after all axes have returned.
