Tapped holes are provided on the back of the base for mounting the actuator. Install the actuator using these
tapped holes. The sizes and effective depths of tapped holes are listed below. Be careful not to let the ends of
bolts project from the holes. If necessary, use the additional reamed holes that are provided for positioning
purpose.
(Two reamed holes are provided, one on the motor side and the other on the counter-motor side. One oblong
hole is provided on the counter-motor side.)
Pay attention when selecting the bolt length. If an inappropriate bolt is used, the tapping hole may be damaged,
actuator installation strength may drop, or contact with the driving parts may occur, resulting in lower precision or
unexpected accidents.

Caution: When using an aluminum-based actuator
If the length of engagement of the screw to be attached into the tapped hole is 5/8 or
smaller than the maximum screw depth of the tapped hole, reduce the torque to 70 to 80%
of the specified torque before tightening the screws.
