2.3 How to Installation
This chapter explains how to install the actuator on your mechanical system.
2.3.1 Installation of Main Unit
The surface to mount the main unit should be a machined surface or a plane that possesses an equivalent
accuracy and the flatness should be within 0.05mm. Also, the platform should have a structure stiff enough to
install the unit so it would not generate vibration or other abnormality.
䎃
Also consider enough space necessary for maintenance work such as actuator replacement and inspection.
On the base there is a datum surface prepared for the attachment slotted holes.
On the back side of the actuator, there are attachment tapped holes, through holes, positioning reamed holes and
slotted holes. For the details of the positions and dimensions, check in the appearance drawings. [Refer to 6.
External Dimensions.]
When repeatability in re-attaching is required after it is detached, utilize the reamed holes. Please note, however,
that a consideration is necessary such as to use only one point on the motor side of the reamed holes when a
fine-tuning such as perpendicularity is required.
(1) Using screws on the rod or head side
Install the actuator using screws set on the rod or head side of the actuator.
