(1) Servo amplifiers and servo motors used
Use the following models of servo amplifiers and servo motors:
Servo amplifier series: MR-J2-10A to MR-J2-350A
Servo motor series : HC-KF -UE
HC-MF -UE
HC-SF
HC-RF
HC-UF
(2) Installation
Install a fan of 100CFM air flow 10.16 cm (4 in) above the servo amplifier or provide cooling of
at least equivalent capability.
(3) Short-circuit rating
Having been subjected to UL's short-circuit test with an AC circuit whose peak current is limited
to 5000A max., this servo amplifier complies with this circuit.
(4) Flange
Mount the servo motor on a flange which has the following size or produces an equivalent or
higher heat dissipation effect:
(5) Capacitor discharge time
The capacitor discharge time is as listed below. To ensure safety, do not touch the charging
section for 10 minutes after power-off.
(6) Options and auxiliary equipment
Use products which conform to the UL/C-UL Standard.
