AC Servo Drivers

Space Around Drivers
•
Install Servo Drivers according to the dimensions shown in the following illustration to ensure proper
heat dispersion and convection inside the panel. Also install a fan for circulation if Servo Drivers are
installed side by side to prevent uneven temperatures from developing inside the panel.
•
Mount the Servo Drivers vertically (so that the model number and writing can be read).

Operating Environment
Be sure that the environment in which Servo Drivers are operated meets the following conditions.
•
Ambient operating temperature:
0
°
C to +55
°
C
•
Ambient operating humidity:
35% to 85% (RH, with no condensation)
•
Atmosphere:
No corrosive gases.
D
Ambient Temperature
•
Servo Drivers should be operated in environments in which there is minimal temperature rise to
maintain a high level of reliability.
•
Temperature rise in any Unit installed in a closed space, such as a control box, will cause the ambient
temperature to rise inside the entire closed space. Use a fan or a air conditioner to prevent the ambi-
ent temperature of the Servo Driver from exceeding 55
°
C.
•
Unit surface temperatures may rise to as much as 30
°
C above the ambient temperature. Use heat-
resistant materials for wiring, and keep separate any devices or wiring that are sensitive to heat.
•
The service life of a Servo Driver is largely determined by the temperature around the internal elec-
trolytic capacitors. The service life of an electrolytic capacitor is affected by a drop in electrolytic vol-
ume and an increase in internal resistance, which can result in overvoltage alarms, malfunctioning
due to noise, and damage to individual elements. If a Servo Driver is always operated at the maxi-
mum ambient temperature of 55
°
C, then a service life of approximately 50,000 hours can be ex-
pected. A drop of 10
°
C in the ambient temperature will double the expected service life.
