Mitsubishi MR-J2-03A5 AC Servo Drive Amplifier

The Mitsubishi MR-J2-03A5 AC Servo Drive Amplifier is a compact, low-power servo drive designed for precise, closed-loop motion control in industrial automation. It provides about 30 W of output power from a 24 VDC input (model variant A5) and supports position, speed, and torque control with encoder feedback, plus auto-tuning, vibration suppression, and electronic gearing. Communication is via RS-232/RS-422 with CN1A/CN1B digital I/O, and it features an LED status/alarm display in a panel-mount, naturally cooled package suitable for 0 °C to 55 °C operation (−20 °C to 65 °C storage) and weighing around 0.2 kg. Typical uses include CNC machinery, indexing tables, pick-and-place, packaging equipment, and automated assembly where high accuracy and smooth motion are required. Common replacements: Mitsubishi MR-J2S-10A, Mitsubishi MR-J3-10A, and Panasonic MINAS A5 50–100W class servo drives.
