XY table origin check
1. Turn the power [ON].
2. Turn ”SERVO MOTOR” on the main con-
trol panel [OFF] then, open the cover and
move the XY table to any position except
origin.
=NOTE=
Make sure that the LED of the limit
sensor is illuminated.
3. Close the front cover and press ”START”
on the main control panel. (This clears the
safety stop).
4. Press “RESET” on the main control pan-
el and turn “SERVO MOTOR” on the
main control panel [ON].
5. Press “MANU” and “ORG” on the main
control panel.
=NOTE=
Make sure that the asterisks of the
X and Y axes blink on the main con-
trol panel display when XY table re-
turns to origin.
=NOTE=
Be careful of safety, since all axes
will return to their origin.

XY table overlimit adjustment
1. Turn the power [ON] and return to origin.
2. Move the XY table in NC AXIS JOG
CHECK and check that the slit board is
not in contact with the sensors.
3. Move the XY table and check the (+), (−)
limit sensors.
=Specification=
X axis overlimit position
(+) limit : 283.00 + 0.1,−0 mm
(−) limit : −328.00 + 0, −0.1mm
Y axis overlimit position
(+) limit : 23.00 + 0.1,−0 mm
(−) limit : −386.00 + 0, −0.1mm
4. If not within the specification, adjust the
sensor bracket position and check again.
