Mitsubishi MR-J4-60B4-RJ010 Servo Amplifier Drive for MELSERVO-J4

The Mitsubishi MR-J4-60B4-RJ010 is an AC servo amplifier drive engineered for precise motion control within the MELSERVO-J4 series. Operating as part of high-performance automated systems, this drive facilitates synchronous multi-axis control through its integrated SSCNET III/H high-speed optical communication interface. It is designed to work seamlessly with compatible servo motors and controllers, offering dependable speed, torque, and position management for automated production machinery. Equipped with a built-in dynamic brake and an internal regenerative braking resistor, the unit ensures controlled deceleration and dissipation of regenerative energy during operational cycles. The servo amplifier is rated for a three-phase AC supply voltage of 380 V to 480 V (400 V class) as well as DC input from 283 V to 340 V. Featuring an IP20 degree of protection, the drive operates effectively across an ambient temperature range of 0 to +55 degrees Celsius. It provides safety unit compatibility and supports MR-J2S conversion architectures, making it suitable for both modern installations and system retrofit applications across packaging, material handling, assembly, and CNC equipment.
