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 to be installed side
4
by 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 the 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.
