Mitsubishi Electric MR-J2-40CT Servo Amplifier

The Mitsubishi Electric MR-J2-40CT servo amplifier provides 0.4 kW of output power in a compact panel-mount unit for precise speed, torque, and position control in automation systems. It runs from a 200–230 VAC, 3-phase supply, uses current/sinusoidal PWM control, and supports encoder-based closed-loop feedback with built-in dynamic braking and protections for overcurrent, overvoltage, overload, and overheating. Interfaces include CN1A/CN1B network ports, CN2 encoder, and CN3 for PC/monitoring, with cooling by forced air or natural convection and an industrial ambient operating range; it weighs about 1.0–1.2 kg. Compatible Mitsubishi motors include HC-SF, HA-FF, and MR-J2 family units, making it suitable for CNC machines, packaging equipment, robotics, and automated production lines such as pick-and-place, conveyors, and semiconductor assembly equipment.
