Mitsubishi MR-J4-10GF1-RJ Servo Amplifier for MELSERVO MR-J4 Series

The Mitsubishi MR-J4-10GF1-RJ (MR-J4-10GF1-RJ) is an AC motion servo amplifier developed for the MELSERVO-J4 series, providing high-precision motor drive performance in automated machinery and production systems. Designed for 400V class operations, the unit accepts a three-phase 380 to 480 VAC power input, delivering a rated output capacity of 1 kW (1,000 W) with a rated current of 2.8 A. It features a multi-network interface supporting EtherCAT communication, enabling seamless real-time synchronization with industrial motion controllers and networks. Equipped with an integrated dynamic brake and a built-in regenerative braking resistor, the MR-J4-10GF1-RJ ensures safe deceleration and effective dissipation of regenerative energy during rapid positioning cycles. The drive is enclosed in an IP20 rated housing and is specified for operation within an ambient temperature range of 0 to +55 degrees Celsius. This servo drive is equivalent to the MRJ4100TM4ECT specification and is widely utilized in industrial applications such as packaging systems, robotics, CNC machine tools, and multi-axis assembly equipment requiring fast response, high dynamic stiffness, and dependable motion control.
