2.3.3 Installation of Rod Type
[1] Installation of Actuator Type Unit
There are two ways to install, one is to use the T-shaped slots on the frame and other to install
vertically with using the flange surface. The installed surface should be a machined surface or a
flat surface which possesses an equivalent accuracy to it, and the flatness should be 0.05mm at
the maximum.
See the appearance drawings for the details of the actuator dimensions. [Refer to Chapter 9]
(1) Mounting Method 1 (When using T slots on frame)
There are T-shaped slots on the frame for installation. Attach the unit directly with using these T
slots or use foot brackets (option).
Square nuts (4 pieces) for T-shaped slot are enclosed in standard.
• Direct Installation
Regarding attachment screws
Caution: Pay attention to the bolt length. It may cause an unexpected accident or failure due
to an insufficient attachment strength if the screws are too long or short.
