Mitsubishi Electric MR-J2S-40A1 Servo Drive Unit

The Mitsubishi Electric MR-J2S-40A1 servo drive unit delivers precise digital servo control for MR-J2S-compatible motors in industrial automation and motion control systems. This panel-mounted drive uses forced-air cooling to provide 400 W of output from a 200 VAC class supply, with an analog and pulse input interface for flexible integration in CNC machines, robotics, packaging equipment, and automated production lines. It is designed to drive Mitsubishi MR-J2S-compatible servo motors, enabling synchronized motion, reliable speed control, and accurate positioning across CNC machining centers, robotic systems, conveyor automation, packaging machinery, and assembly lines. Common replacements include MR-J2S-40A, MR-J3-40A, and SGDV-1R6A01A.
