2.5.2 VARIABLE TOOL CHANGE POINT
If the manufacturer wishes the user can be allowed to define the tool change point at all times. This
feature logically depends on the type of machine and type of changer.
This feature allows the tool change to be made beside the part, thus avoiding movements to a change
point farther away from the same.
To allow this:
Define text 47 of the program 999997 for the CNC to request the coordinates on X and Z of the
change point.
For example: ;47 $CHANGE POSITION
These coordinates should always refer to machine reference zero (home), for the zero offsets not
to affect the tool change point.
Remember that the CNC can display, along with coordinates X, Z and in small characters, the
coordinates for the axes referring to home (text 33 of program 999997).
Since the tool change point can be modified by the operator at any time, the subroutine associated
with the tools must take these values into account.
Arithmetical parameters P290, P291 and P292 contain the values set by the operator as change
position on X, Z.

Press
to select the "T" . Then press key for the relevant axis
or:
After moving over the coordinates for the axis to be defined, one can:
a) Enter the value manually. Key in the value required and press
b) Assign the present position of the machine.
Move the axis, by means of the handwheel or the JOG keys, up to the point required.
Press
. The CNC assigns said coordinate to the field selected.
