5.1 Servo Amplifier Installation
Refer to the following for the Servo Amplifier installation place and procedure.
5.1.1 Installation Place
Install the Servo Amplifier by referring to the following.
Case Precautions
When installing
the Servo
Amplifier in a box
The temperature in the box may be higher than the outside temperature depending
on the power loss of built-in equipment and the dimensions of the box.
Be sure to keep the temperature around the Servo Amplifier at 55℃ or lower by
properly determining the dimensions of the box, the cooling system and the
arrangement.
For a longer lifetime and higher reliability, operate the Servo Amplifier at an in-box
temperature of lower than 40°C.
When there is a
vibration source
nearby
Install the Servo Amplifier at the base through a shock absorber so that vibration
may not be transmitted directly to the Servo Amplifier.
When there is a
heat generating
source nearby
Even it there is a possibility that a temperature rise may be caused by convection or
radiation, keep the temperature near the Servo Amplifier lower than 55°C.
When there is
corrosive gas
If the Servo Amplifier is operated for a long time, contact failure will come to occur at
contact parts (e.g., connectors). So, never install the Servo Amplifier in corrosive
gas atmosphere.
When there is
explosive gas or
combustible gas
Never install the Servo Amplifier in explosive gas or combustible gas atmosphere.
Relays and contactors, which generate arcs (sparks) inside boxes, and such parts
as regenerative brake resistor may become ignition sources, causing fires and
explosion.
When there is
dust or oil mist
Never install the Servo Amplifier in such atmosphere containing dusts or oil mists.
Dusts or oil mists adhered to or accumulated on the Servo Amplifier may lower
insulation or cause leak between conductors of applicable parts, damaging the
Servo Amplifier.
When there is a
large noise
source
Induction noise will enter input signals and the power supply circuit, causing Servo
Amplifier’s malfunction.
When there is a possibility of noise entering, take proper measures such as inserting
a noise filter, revising line wiring and preventing noise generation.
