Mitsubishi Electric MR-J4W2-22B Servo Amplifier

The Mitsubishi Electric MR-J4W2-22B Servo Drive is a compact dual-axis AC servo amplifier that drives two servo motors in synchronized motion for precise positioning, speed, and torque control. Part of the MELSERVO-J4 series, it provides 2 axes with a rated output of 200W per axis (0.2 kW x 2) and accepts 200–240 VAC, 3-phase power, enabling efficient multi-axis control in automation projects. It uses advanced servo control with auto-tuning, with feedback from a high-resolution absolute encoder compatible system, and communicates via SSCNET III/H for deterministic, high-speed coordination. The unit offers a frequency response up to 2.5 kHz and includes built-in STO (Safe Torque Off) for safety, with cooling that can be natural or forced air and a panel-mount design suitable for compact installations. Common applications include robotics, CNC machines, packaging equipment, gantry and pick-and-place systems, conveyor synchronization, electronic assembly equipment, and other high-speed manufacturing environments that require coordinated dual-axis motion and space-saving design. For replacement or retrofit considerations, common compatible models include MR-J4W2-44B, MR-J4W-20B, and MR-J3W-22B, which can simplify asset management and upgrades while maintaining the same core performance and interface expectations.
