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. Also if the Servo Drives are installed side 
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 operating temperature: 0 to 55°C (Take into account temperature rises in the individual 
Servo Drives themselves.)
Ambient operating humidity: 90% RH max. (with no condensation) 
Atmosphere: No corrosive gases.
