You can load the zero point shift and the tool change point
by soft key (see soft-key table).
 The setting in the "TC point" form applies only within the
current program.
 Position of tool change point (WX1, WZ1, WY1):
 If the tool change point is defined, you use G14 to
move to this position.
 If the tool change point is not defined, you use G14 to
move to the position defined in manual mode.
If you call a subprogram using the start unit, you should set
the subprogram with G65 Chuck selection with fixture D0.
You should also move the C axes out, for example with
M15 or M315.
