Servo Drive Installation Conditions
Dimension Conditions around Equipment
Install drives according to the dimensions shown in the following illustration to ensure proper heat
dispersion inside the drive 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.
Servo 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). For ambient temperature requirements, refer to
Environment Operating Conditions below.
If the mounting surface of the Servo Drive is coated, remove the coating to allow electrical
conduction. If you make your own mounting bracket, we recommend that you apply electrically
conductive plating.
Mounting Direction
Mount the drives in a direction (perpendicular) so that the model number can be seen properly.
Environment Operating Conditions
The environment in which drives are operated must meet the following conditions. Drives may
malfunction if operated under any other conditions.
Operating ambient temperature: 0 to 55C (Take into account temperature rises in the following
individual drives themselves.)
Operating humidity: 90% RH max. (with no condensation)
Operating atmosphere: No corrosive gases.
Altitude: 1,000 m max.
For Servo Drives of 100 V or 200 V with a capacity of 750 W max., the specifications for operating
ambient temperature depend on the Servo Drive (A, B, and C) when the clearance between Servo
Drives is 1 mm.
Drive A : 0 to 50C
Drive B : 0 to 40C
Drive C : 0 to 45C
