Specification

The Mitsubishi Servo Drive MR-J3-700A is a 7.5kW industrial servo amplifier designed for demanding automation applications. It delivers exceptional performance with a sine-wave PWM current control system, supporting precise positioning, speed regulation, and torque control. This model is engineered for 3-phase 200 to 230VAC input, featuring a built-in regenerative resistor (170W) and external regenerative resistor capability for higher power models. With a maximum input pulse frequency of 1Mpps (differential) and encoder resolution of 262144 p/rev, the MR-J3-700A ensures high-speed, accurate motion in CNC, robotics, and packaging machinery. It includes comprehensive protection functions and operates reliably in industrial environments from 0 to 55°C.
