7-17 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
sensor. If the clearance between the sensor and the detector plate is changed, the mechanical
home position is also changed. If such deviation occurs happened, make the following
adjustment. When adjusting, the red pilot lamp on the sensor will light when the home is
detected, so the home position can be confirmed.
7-17-1 Adjustment of the X detector clearance
1) Remove the X cover (right) and the X cover plate (right).
2) Check the clearance between the surface of the detector (No.1) and the detector plate (No.2). If this
clearance is about 1.0 to 1.5mm, it is the normal condition.
3) If this clearance is out of the normal condition, loosen the detector set screws (No.3) and move the
detector by hand then, adjust the clearance to be proper.
4) After the adjustment, make the detector surface (No.1) parallel with the detector plate (No.2) then,
tighten the detector set screws (No.3) securely.
7-17-2 Adjustment of the Y detector clearance
1) Remove the Y detector cover.
2) Check the clearance between the detector surface (No.4) and the Y driving shaft (No.5). If this
clearance is about 1.0 to 1.5mm, it is the normal condition.
3) If this clearance is out of the normal condition, loosen the set screws (No.7) and reset the detector
mounting plate (No.6) to the proper position to be able to get the normal detector clearance.
4) After the adjustment, tighten the set screws (No.7) of the detector mounting plate (No.6) securely.
CAUTION
★If the detector clearance becomes more than 1.5mm, 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.
