6.2.2 Precision of the Installation Surface
x The frame on which the actuator is installed shall have sufficient structural rigidity to remain free from vibration,
etc.
x The basis of measurement of the running accuracy of the slider is from the lower side and motor side to right
side.
If accuracy for its run is required, use these surfaces as a datum of the installation.
In view of the motor side, the parallelism of the quasi-reference surface of left side to the reference surface is
0.1mm or less.
x The surface where the actuator, excluding the high-precision straightness specification (model number: ST
(optional)), will be mounted should be machined or be equally level, and the flatness between the actuator and
the frame should be within 0.05 mm/m. If the installation surface is rough, abnormal noise or other problems
may occur due to poor contact of the actuator.
x Install the actuator, excluding the high-precision straightness specification (model number: ST (optional)), after
removing any dirt on the base surface on a flat surface with a precision of the flatness of 0.02 mm/m.
[For the high-precision straightness specification (model number: ST (optional)), refer to 10.8, “High-Precision
Straightness Specification.”]
x Provide enough space around the actuator so that maintenance work can be carried out.
