7-16. Adjustment of the X-Y detector clearance
[NOTE] The work holder stop position which is the mechanical home position is detected
by the X-Y detectors. If the clearance between the detector and the detector
plate is changed, the mechanical home position is also changed. If such
aberration is happened, make the following adjustment. Please keep it in mind if
the detector senses the home position, the red pilot light of the detector goes on
each time.
7-16-1. Adjustment of the X detector clearance
(1) Remove the X detector cover.
(2) Check the clearance between the surface of the detector and the detector plate. If this
clearance is about 1.5～2.5mm, it is the normal condition.
(3) If this clearance is out of the normal condition, loosen the set screws (NO.) and move
the detector plate, then adjust the clearance to be proper.
(4) After the adjustment, make the detector surface parallel with the detector plate then,
tighten the set screws (NO.) securely.
7-16-2 Adjustment of the Y detector clearance
The clearance between the detector surface and Y-drive shaft is set to 1.5mm.
There is no adjustable space in this clearance.
If the detector clearance becomes more than 2.5mm, the work holder stop
position becomes unstable, furthermore, if the clearance becomes far bigger
than 2.5mm the work holder does not stop and becomes out of control.
