The recommendation example of the cabinet for servo amplifier
in consideration of tolerance of environment and heat
dissipation performance
1. Outline
In order to increase the reliability by the installation environment of the servo
amplifier, the sealing performance of the cabinet and the consideration to environment
inside cabinet are important.
In this report, the important point for cabinet design is indicated.

2-1 Sealing
performance
of cabinet
The method for the securement of sealing performance
of the cabinet is described.
It is necessary to install the servo amplifier in the
sealed type cabinet for protection of the electronic
circuit portion of the servo amplifier.
2-2 Environment of
heat sink part of
amplifier
The method for reducing adhesion of the cutting fluid,
oil mist or cutting chips to the heat sink part is
described.
Adhesion of the cutting fluid, oil mist or cutting waste
to the heat sink part or the fan motor of the servo
amplifier becomes the cause that reduces the cooling
efficiency of the servo amplifier (performance
decrement of amplifier), and shortens the life of
electronic parts (ex. a power semiconductor module, a
fan motor).
2-3 Installation
environment
of amplifier
The important point in the installation environment of
the amplifier is described.
If the performance of heat dissipation falls because of
the installation environment of the servo amplifier, it
will become the cause that reduces the performance
of the amplifier, and shortens the life of electronic
parts (ex. Power semiconductor module, Fan motor).
