Servo Drive Installation Conditions
Space Conditions around Servo Drives
 Install the Servo Drives according to the dimensions shown in the following illustration to ensure
proper dispersion of heat from inside the drives and convection inside the panel. If the drives are
installed side by side, install a fan for air circulation to prevent uneven temperatures inside the
panel.
Mounting Direction
 Mount the drive perpendicular on the panel so that the model number reads normally.
Environment Operating Conditions
 The environment in which drives are operated must meet the following conditions. Drives may
malfunction if operated under any other conditions.
Ambient operating temperature: 0 to 55°C (Take into account the following temperature rises
in the individual drives themselves.)
Operating humidity: 90% max. (with no condensation)
Operating atmosphere: No corrosive gases.
Altitude: 1,000 m max.
 Drives of 100 V or 200 V with a capacity of 750 W max. can be installed side by side with a 1-mm
clearance (W in above illustration). However, the specifications for operating ambient temperature
depends on the drive.
Drive A: 0 to 50°C
Drive B: 0 to 40°C
Drive C: 0 to 45°C
