19 – 296 HEIDENHAIN Service Manual iTNC 530 HSCI
8 Write down the displayed REF value.
(If required, subtract the position value defined by the machine manufacturer.)
8 Invert the displayed REF value (or the result).
8 Add this value to the value in MP960.x for the axis concerned and enter the result.
Example 1: Positioning to the machine datum (e.g., using a touch probe system)
Example 2: Positioning to a reference mark defined by the OEM (e.g., using a touch probe system)
8 Check, whether the new machine datum is correct
(e.g., with M91).
8 If required, reset the traverse range to its original values.
8 Check the proper function of the tool changer.
8 Set the display to ACTL.
8 If necessary, ask the customer to mill a workpiece and check it for dimensional accuracy.
Further information --> See ”Reference run” on page 20 – 323.
You may have to expand the traverse range (software limit switches).
(The software limit switches are defined as of MP910.x. The operator may have limited the
traverse range even further.)
A: Displayed REF value -0.123 mm
B: Position value defined by the OEM at this position +0.000 mm
C: A - B -0.123 mm
D: Inverted value of C +0.123 mm
E: Original entry in MP960.x +630.500 mm
F: D + E = New entry in MP960.x 630.623 mm
A: Displayed REF value 299.877 mm
B: Position value defined by the OEM at this position 300.000 mm
C: A - B -0.123 mm
D: Inverted value of C +0.123 mm
E: Original entry in MP960.x +630.500 mm
F: D + E = New entry in MP960.x 630.623 mm
Activate the axis compensations and kinematics settings and determine them again, if necessary.
