Mitsubishi Electric MR-E-70A AC Servo Amplifier

The Mitsubishi Electric MR-E-70A AC Servo Amplifier is a MR-E (MELSERVO) series device that drives servo motors in industrial automation, delivering encoder-based closed-loop control for precise speed, torque, and position in CNC equipment, robotics, conveyors, packaging systems, and automated production lines. It is rated for 0.75 kW (750 W) output and accepts 3-phase 200–230 VAC (1-phase 230 VAC supported) at 50/60 Hz, providing about 5.8 A of output current with position, speed, and torque control modes. Interface options include analog input, pulse input, and RS-232 communication (model dependent); cooling is forced air, and the unit mounts in a control cabinet (panel-mount) for operation in environments 0°C to 55°C with protection features for overcurrent, overvoltage, overload, and overheating. Weight is approximately 1.8–2.0 kg and, as a discontinued/legacy MR-E series product, it is commonly considered alongside Mitsubishi replacements such as MR-J3-70A, MR-J4-70A, and MR-JE-70A.
