2. INSTALLATION
(b) Installation of two or more servo amplifiers
Leave a large clearance between the top of the servo amplifier and the internal surface of the control box,
and install a cooling fan to prevent the internal temperature of the control box from exceeding the
environmental conditions.
When installing the servo amplifiers closely, leave a clearance of 1mm between the adjacent servo
amplifiers in consideration of mounting tolerances.
In this case, bring the ambient temperature within 0 to 45 , or use it at 75% or smaller effective load ratio.
