Note
You may have to expand the traverse range (software limit switches)!
(The software limit switches are defined as of MP 910.x. It is also possible that the operator
has limited the traverse range even further.)
Write down the displayed REF value (if necessary, abstract the value defined by the machine
manufacturer).
Invert the REF value displayed (or the result).
Add this value to the value in MP 960.x for the axis concerned and enter the result.
A: REF value displayed
B: Position value defined by the OEM at this position
C: A - B
D: Inverted value of C
E: Original entry in MP 960.x
F: D + E = New entry in MP 960.x
A: REF value displayed
B: Position value defined by the OEM at this position
C: A - B
D: Inverted value of C
E: Original entry in MP 960.x
F: D + E = New entry in MP 960.x
Check, whether the reset machine datum is correct (e.g., with M91)!
If required, reset the traverse range to its original values.
Note
Activate the axis compensations and kinematics settings and determine them again, if
necessary. --> Ask the machine manufacturer.
Check the function of the tool changer.
Set the display to ACTL.
If necessary, instruct the customer to mill a work piece and check it for dimensional accuracy.
