Precautions
• For the availability of close mounting, refer to "Servo amplifier standard specifications" in the User's Manual (Introduction).
• When closely mounting multiple servo amplifiers, the servo amplifier on the right must have a larger depth than that on the
left. Otherwise, the CNP1, CNP2, and CNP3 connectors cannot be removed.
Installation clearances for the servo amplifier [WG]
■Installation of one servo amplifier
Servo amplifier
10 mm
or more
■Installation of two or more servo amplifiers
Maintain a large clearance above the servo amplifiers and install a cooling fan to prevent the temperature inside the cabinet
from exceeding the temperature specified in the environmental conditions.
When closely mounting the servo amplifiers, leave a clearance of 1 mm between the adjacent servo amplifiers in
consideration of mounting tolerances.
When mounting servo amplifiers in this manner, keep the ambient temperature within 0 °C to 45 °C, or use the servo
amplifiers with 75 % or less of the effective load ratio.
