CONFORMANCE WITH UL/C-UL STANDARD
(1) Servo amplifiers and servo motors used
Use the servo amplifiers and servo motors which comply with the standard model.
Servo amplifier :MR-J3-10B to MR-J3-700B
MR-J3-10B1 to MR-J3-40B1
Servo motor :HF-MP
HF-KP
HF-SP
(2) Installation
Install a fan of 100CFM (2.8m
at least equivalent capability.
(3) Short circuit rating
This servo amplifier conforms to the circuit whose peak current is limited to 5000A or less. Having been
subjected to the short-circuit tests of the UL in the alternating-current circuit, the servo amplifier conforms to
the above circuit.
(4) Capacitor discharge time
The capacitor discharge time is as listed below. To ensure safety, do not touch the charging section for 15
minutes after power-off.
