check that the sensor does not interfere with other parts while turning the X-
axis arm by hand.
16) Go out of the safeguard enclosure, and check that no one is inside the safe-
guard enclosure. Then turn on the controller.
17) Perform the absolute reset from outside the safeguard enclosure.
18) After the absolute reset is completed, read the machine reference value dis-
played on the MPB.
19) If the machine reference value is in the range between 40 and 60 (recom-
mended range), then the origin position has been correctly changed. Fully
tighten the bolts to secure the X-axis origin sensor stay. If it is outside the
recommended value, then adjust the machine reference by referring to "1-1
Adjusting the X-axis machine reference".
