19 – 298 HEIDENHAIN Service Manual iTNC 530 HSCI
8 Read the values of the REF display for the master and slave axis. The values will differ slightly.
8 Add the difference of the displayed values to the value in MP960.x for the axis with the newly
mounted encoder.
8 Enter the result.
Example 1: Position encoder of the slave axis was remounted
Example 2: Position encoder of the master axis was remounted
8 Check, whether the values of the new axis are correct (master or slave):
If the algebraic sign is wrong, the difference is twice as large.
If the calculation is correct, the displayed values will be the same for master and slave axis.
8 Reset MP860.x to its original value.
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.

D: Original entry in MP960.x for the slave axis +2000.000 mm
F: C + D = New entry in MP960.x 2000.345 mm
A: Displayed REF value for master axis 499.678 mm
A: Displayed REF value for slave axis 500.000 mm
C: Difference between A and B +0.322 mm
D: Original entry in MP960.x for the master axis +0.000 mm
F: C + D = New entry in MP960.x 0.322 mm
Activate the axis compensations and kinematics settings and determine them again, if necessary.
--> Ask the machine manufacturer.
The machine manufacturer could also check the geometry of the gantry axes.
