4-1 Installation Conditions

Servo Drives

 Space around Drives
• Install Servo Drives according to the dimensions shown in the following illustration to ensure
proper heat dispersion and convection inside the panel. If the Servo Drives are installed side by
4
side, install a fan for air circulation to prevent uneven temperatures from developing inside the
panel.
 Mounting Direction
• Mount the Servo Drives in a direction (perpendicular) so that the model number can be seen
properly.
 Operating Environment
• The environment in which Servo Drives are operated must meet the following conditions. Servo
Drives may malfunction if operated under any other conditions.
 Ambient Temperature Control
• Servo Drives 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 Drive's ambient temperature to rise. Use a fan or air conditioner to prevent the Servo Drive's
ambient temperature from exceeding 55°C.
• Servo Drive surface temperatures may rise to as much as 30°C above the ambient temperature.
Use heat-resistant materials for wiring, and keep its distance from any devices or wiring that are
sensitive to heat.
• The service life of a Servo Drive is largely determined by the temperature around the internal
electrolytic capacitors. The service life of an electrolytic capacitor is affected by a drop in
electrostatic capacity and an increase in internal resistance, which can result in overvoltage
alarms, malfunctioning due to noise, and damage to individual elements.
