3.1 Servo amplifier
3.1.1 Precautions
When installing, please be sure to protect the following precautions.
■
Various precautions
The device should be installed on non-flammable surfaces only. Installation on or near
flammable materials can cause fire.
Do not stand on, or put heavy items on the servo amplifier.
Operate the device within the specified environmental conditions.
Do not drop the device or subject it to excessive shock.
Make sure no screws or other conductive or flammable materials get inside the servo amplifier.
Do not obstruct the air intake and exhaust vents. The mounting direction should be observed
strictly.
Please contact our office if the amplifier is to be stored for a period of 3 years or longer. The
capacity of the electrolytic capacitors decreases during long-term storage.
Any damaged parts or the products which have damaged parts shall be repaired by returning it
to our company immediately.
■
If enclosed in a cabinet
The temperature inside the cabinet might exceed the external temperature depending on the
power consumption of the device and the size of the cabinet. Consider the cabinet size, cooling,
and placement, and make sure the temperature around the servo amplifier does not exceed
55°C. For longevity and reliability purposes it is recommended to keep the temperature below
40°C.
■
If there is a vibration source nearby
Protect the servo amplifier from vibration by installing it on a base with a shock absorber.
■
If there is a heat generator nearby
If the ambient temperature might increase by convection or radiation, make sure the temperature
near the servo amplifier does not exceed 55°C.
■
If corrosive gas is present
Long-term use may cause contact failure on the connectors and connecting parts. Never use the
device where it may be exposed to corrosive gas.
■
If explosive or combustible gas is present
Never use the device where explosive or combustible gas is present.
The device’s relays and contactors, regenerative resistors and other parts can generate arc
(spark) and can cause fire or explosion.
■
If dust or oil mist is present
The device cannot be used where dust or oil mist is present. If dust or oil mist accumulates on
the device, it can cause insulation deterioration or leakage between the conductive parts, and
damage the servo amplifier.
■
If a large noise source is present
If inductive noise enters the input signals or the power circuit, it can cause a malfunction. If there
is a possibility of noise, inspect the line wiring and take appropriate noise prevention measures. A
noise filter should be installed before the servo amplifier.
