5) Location Detector Assembly and
Adjustment
(1) Installing the location detector
A. Installing on the servo motor (in-built location detector)
A location detector sensor is attached to the back side of
the arm. The appropriate clearance between the location
detector and the pulley is 0.5mm. (See Fig. 7)
After assembling the parts in the numbered order as in Fig. 8, adjust the synchronization shaft horizontally such that the
photo film is placed at the center of the photo interrupter as in Fig. 9. Then fasten it tightly with two fixing screws using a
hexagonal wrench.
[Caution]
Assemble after adjusting the position such that the letters “ UP ” and “ DOWN ” are facing the front side when
seen from the pulley as is shown in Fig. 8.
The film will already be adjusted by default.
