Mitsubishi Electric MR-J3-100A Servo Amplifier

The Mitsubishi Electric MR-J3-100A Servo Drive paired with the HF-SP102B servo motor is a digital servo control system designed for precise motion, high-speed response, and accurate positioning in industrial automation. This 1.0 kW drive, part of the MR-J3 Series and designed to operate with the HF-SP Series motor, runs from 3-phase AC 200–230 VAC and delivers a typical 2000 RPM, using digital servo control with an incremental encoder for high-resolution closed-loop performance. The system combines a panel-mounted drive with a flange-mounted motor, employing forced-air cooling for the drive and natural cooling for the motor, and is suitable for CNC machines, robotics, packaging equipment, conveyors, and automated production lines that require coordinated servo performance. Common replacements include Mitsubishi MR-J3-100A + HF-SP102B, MR-J4-100A + HG-SR102, and MR-J2S-100A + HF-SP102B servo systems.
