The Mitsubishi MR-JE-70A is a 750 W servo amplifier in the MR-JE-_A series, rated at 5.8 A for 200-240 VAC single- or three-phase supply. It packs a built-in dynamic brake, which saves panel space and wiring time compared to adding an external resistor pack. IP20 natural-cooled enclosure keeps the cabinet free of fan noise and air filters—just bolt it to the backplate with the recommended clearance for airflow.
Control is sine-wave PWM with current-loop control—standard for high-torque-at-low-speed applications like indexing tables or pick-and-place. The 2.0 kHz speed frequency response is enough for most positioning profiles; if your servo update rate is faster you would step up to the MR-JE-_B family. Input power is 200-240 VAC, 50/60 Hz, single or three phase—check your line configuration: on single phase you get slightly reduced peak torque versus three phase. Rated output current of 5.8 A matches a 750 W rotary servo motor with a winding voltage in that range. The dynamic brake is triggered on a servo off or fault condition without an external contactor.
