Mitsubishi Electric MR-J2S-40A AC Servo Amplifier Drive

The Mitsubishi Electric MR‑J2S‑40A AC Servo Amplifier Drive is a motion control device that powers and precisely controls Mitsubishi series AC servo motors in CNC machining centers, robotic arms, automated conveyors, pick‑and‑place systems, and packaging machinery, delivering accurate speed, torque, and position feedback. It provides a 4.0 A rated output current, operates from 200–230 VAC, 3‑phase, and uses pulse train input control with position, speed, and torque feedback, with encoder feedback compatibility and built‑in fan cooling. This panel‑mount drive supports 50/60 Hz operation, offers protection features including overcurrent, overvoltage, overheat, and short‑circuit protection, and is rated for 0°C to 50°C ambient with storage from -20°C to 65°C. Communication options include Pulse/Direction or CC‑Link via optional modules, and it provides LED run/alarm indicators; common replacements include Mitsubishi MR‑J2S‑40B, Yaskawa SGDV‑R90A01A, and Panasonic MINAS A5 Servo Drive 400W.
