18. MR-J4-03A6 SERVO AMPLIFIER
(2) Installation of two or more servo amplifiers
Leave a large clearance between the top of the servo amplifier and the cabinet walls, and install a
cooling fan to prevent the internal temperature of the cabinet from exceeding the environment.
When mounting the servo amplifiers closely, leave a clearance of 1 mm between the adjacent servo
amplifiers in consideration of mounting tolerances. In this case, operate at the ambient temperatures 0
˚C to 45 ˚C.
