Description
The Mitsubishi MR-J4-40B is a 400 W AC servo amplifier belonging to Mitsubishi Electric’s MELSERVO-J4 series. It’s an industrial automation component that controls a small to medium-sized AC servo motor for precise positioning, speed, and torque control.
Here’s a breakdown of the MR-J4-40B’s key features and functionalities:
- AC Servo Amplifier: Electronically controls the power delivered to a connected AC servo motor, enabling controlled motion.
- 400 W Power Rating: Provides a maximum power output of 400 watts (W) to drive the motor.
- MELSERVO-J4 Series: Part of the MELSERVO-J4 family of servo amplifiers from Mitsubishi Electric, recognized for reliability and performance.
- Possible Features:
- Built-in dynamic brake for holding the motor shaft stationary when powered off, enhancing safety (presence not always guaranteed, check specifications).
- Advanced control modes like position control, velocity control, and torque control for creating diverse motion profiles.
- Communication protocols like SSCNET III/H for integration with industrial controllers and Human-Machine Interfaces (HMIs).
- IP20 environmental rating, indicating suitability for indoor environments with limited dust and moisture.
Applications: 
- Machine Tools: Precise positioning and control of cutting tools in smaller CNC machines, lathes, or drilling machines.
- Robotics: Joint actuation in robots for various tasks like assembly, material handling, and pick-and-place operations requiring moderate torque.
- Conveyor Systems: Controlled movement of materials on conveyor belts for production lines involving lighter to moderately heavy loads.
- Packaging Machinery: Precise positioning and control of packaging materials for medium-speed operations.
- Textile Machinery: Precise control of motors driving yarn or fabric in textile production processes, suitable for handling materials with moderate thickness or density.
