reference position. When performing an absolute reset for arm 2, set an adjustment jig (pin) in arm 2 to fix
the arm at the reference position.
- Set the jig after confirming that the EMERGENCY STOP switch is pressed.
- Set the jig after adjusting the arm to the reference position, using the positioning mark label as a guide.
- Only arm 1 has a cover, which is fixed with setscrews. Remove the setscrews and remove the cover
before setting the jigs.

rotation data can be reset as long as positioning preciseness of "center of positioning mark label ± 1
graduation" is ensured.
- To perform an absolute reset for arm 2 with an arm length of 120, turn the arm at a right angle and set the
jig as shown in the reference position drawing in Fig. 14.17.
