(7) When performing an absolute reset for arm 1, set an adjustment jig (pin) in arm 1 to fix the arm at the
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.

It is recommended that an adjustment jig is used to perform an absolute reset. With arm 1 or 2, however,
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. 13.17.


Always press the EMERGENCY STOP switch before setting an adjustment jig. Failure to do so may
cause the actuator to malfunction and result in a serious accident.
