9.3 Installation of Tool and Load
(1) Installing the tool
 The tool mounting part must have sufficient strength and rigidity, along with adequate fastening power to
prevent positional shift.
 It is recommended that a tool be installed over a split ring, power lock or other appropriate part.
(The flanges specified in 4, "Options" are available.)
 To set the rotating direction using the D-cut surface and setscrews, be sure to use setscrews with resin
or brass pad or set pieces made of soft material.
 An example of installation is shown below for your reference.
Caution: Use the D-cut surface at the tip of the R-axis (rotational axis) to position the R-axis.
Avoid attachment of the tool at the D-cut surface via thread fastening. Doing so may
damage the D-cut positioning surface.
Design the tool so that it will not contact any device that secures the ZR unit.
