Installation Conditions

3-1-1 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.
• Take the control cable's connector direction into account when installing the Servo Drivers.
30 mm min.
Mounting Direction
■
Mount the Servo Drivers in a direction (perpendicular) such that the lettering for the model number,
and so on, can be seen.
Operating Environment
■
The environment in which Servo Drivers are operated must meet the following conditions.
• Ambient operating temperature: 0 to 55 ° C (Take into account temperature rises in the individual
Servo Drivers themselves.)
• Ambient operating humidity: 90% max. (with no condensation)
• Atmosphere: No corrosive gases.

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 Servo
Driver's ambient temperature to rise. Use a fan or air conditioner to prevent the Servo Driver's ambi-
ent temperature from exceeding 55 ° C.
• Servo Driver 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.
