Mitsubishi Electric MR-J2S-200B AC Servo Drive

The Mitsubishi Electric MR-J2S-200B AC Servo Drive is a 200–230 VAC, 3-phase servo amplifier that provides precise speed and torque control for Mitsubishi AC servo motors in industrial automation systems. It delivers a rated output current of 20.0 A and uses a pulse-train input with closed-loop feedback to achieve accurate position and speed control, with encoder-compatible feedback for position or speed tasks. Commonly deployed in CNC machines, robotic arms, automated conveyors, pick‑and‑place systems, packaging machinery, and automated production lines, this drive is designed for panel mounting and includes a built-in cooling fan. It supports Pulse/Direction communication with options for fieldbus modules and carries protection features such as overcurrent, overvoltage, overheat, and short-circuit protection. Operating temperature ranges from 0°C to 50°C, with storage from −20°C to 65°C, and LED run/alarm indicators provide quick status checks. For system upgrades or replacements, MR-J2S-200B is part of the Mitsubishi MR-J2S family and is commonly referenced alongside MR-J2S-200A as a replacement option.
