Mitsubishi MR-J2S-700B Servo Drive

The Mitsubishi MR-J2S-700B Servo Drive is a high‑power AC servo drive in the MELSERVO-J2-Super series that delivers 7.0 kW of output from a 200–230 VAC, 3‑phase supply for precise position, speed, and torque control in demanding automation tasks. Widely used in CNC machines, heavy‑duty automation equipment, packaging lines, and robotics, it provides reliable, high‑torque motion with stable multi‑axis coordination and strong load performance. Key specifications include sinusoidal PWM control, incremental encoder feedback compatibility, SSCNET communication, and an approximate 550 Hz frequency response, along with protection functions for overcurrent, overvoltage, overload, and overheating. Cooling is achieved by forced air, and the unit mounts on a panel. Common replacements for this drive include Mitsubishi MR-J2S-500B, MR-J2S-1000B, and MR-JE-70A for retrofit or upgrade projects. This servo drive is typically selected by maintenance teams, OEMs, and system integrators when high power, precise control, and reliable multi‑axis coordination are required in machines tools, material handling systems, large conveyors, printing machines, and industrial robotics.
