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).
(1) Installation of a heat exchanger
When the inside temperature of a cabinet is higher than the ambient air
temperature of a cabinet 10 degrees or more, install a heat exchanger for
decreasing temperature.
※1: When you install a heat exchanger, seal the circumference by packing not
to spoil the sealing performance of a cabinet.
※2: Keep the wind of a heat exchanger from blowing to amplifier or electronic
components directly. (The mist in a cabinet may be sprayed.)
(2) Installation of the fan motor for internal stirring
If the fan motor for air stirring is installed in the inside of cabinet, equalization of
the inside temperature of cabinet can be achieved, and the heat dissipation
efficiency of cabinet can be increased. (Fig. 14)
※1: Don't block the stirring air of fan motor by installing cables etc. at outlet.
※2: Keep the wind of a fan motor from blowing to amplifier or electronic
components directly. (The dirt in a cabinet may be sprayed.)
