6. Machine Accuracy Measurement and Adjustment
※ Note) Resetting the B-axis reference point
(1) By referring to “Table top and X-axis feed parallelism” above, measure
the exact parallelism.
(2) Measure the table top in the X-axis direction while moving the B-axis in
the “Handle” Mode and adjust until both ends become “0.”
(3) In the “MDI” Mode, change parameter #1815 B row b4(APZ) from “1”
to “0 ”.
☞ “P/S Alarm 000 Must Turn Off Power” and “ P/S Alarm 300 nAxis
Need ZRN” will be triggered.
(4) Change again Parameter #1815 B row b4(APZ) from “0” to “1” and
then turn the NC Power “Off” and “On”.
☞ When the alarm is canceled, the B-axis position on the screen
changes to "B0.000".
