Specifications
The transport plate does not set the installation standard for the rotary magnescale.
Perform the installation by following section 5-1, “Installation Dimensions and
Tolerance.”

Rotary Magnescale Installation
Installation Dimensions and Tolerance
Make preparations so that the rotary magnescale installation surface dimensions and tolerance have
the values shown in the figure below.
Installation Preparation
Transport plate is used to secure the scale unit and scale shaft so that excess vibrations are not
applied to the scale shaft during transportation. Before installing the rotary magnescale, be sure to
remove the transport plate.
Installation Precaution
·If the surface of the rotary side or stationary side where the rotary magnescale will be installed has paint
or other coating, remove the paint or coating in order to obtain conductivity between the rotary
magnescale
and the machine.
·Before installing the rotary magnescale, be sure to check that the dimensional tolerance of the
installation surface and machine shaft are within the standards. If the installation dimensional tolerance
is not within the standards, the required accuracy will not be obtained, and the rotary magnescale can
even be damaged.
·In environments where coolant can splash directly on the rotary magnescale, be sure to mount a cover
on the rotary magnescale to protect the rotary magnescale from splashing.
·The installation nut and other installation tools must be obtained by the customer.
·The absolute position becomes 0 at the reference point mark ±2 degrees. Be sure to check its location
when securing the scale shaft. (See section 6, “Outside Dimensions.”)
·In its standard configuration, the rotary magnescale has an M5 tap hole for air injection.
