•
Provide appropriate ventilation as required to prevent excessive rise of the ambient temperature
since the heat is dissipated into the air.
•
If the rise of the ambient temperature must be suppressed for a certain application, or if the
moving table dimensions are small, calibrate the cooling system separately to cool the Motor Coil
Unit.

Rigidity of Linear System
The response performance of a linear system is affected by the rigidity of the Linear Slider. Ensure
that the rigidity is appropriate for the required performance. If a gain is set to higher than the
machine rigidity, the vibration occurs.
Take the following measures to improve rigidity.
•
Use preloaded linear guides. This makes the Linear Slider highly rigid with less play in the
mechanical system.
•
Ensure the rigidity of the base material to which the Linear Slider is secured. The materials in
descending order of rigidity: granite, steel, and aluminum.
•
The moving table must have a sufficient thickness to prevent deformation and vibration.
•
Install the Magnet Track and external encoder in a straight and parallel line.
•
Install the external encoder as close to the Motor Coil Unit as possible.

Notice
Each Magnet Track unit includes a protective cover that
reduces the effect of the magnetic field. Do not remove this
protective cover until the Magnet Track installation is
completed.
