Mitsubishi MR-J4-10A1-RJ Servo Amplifier for MELSERVO-J4

The Mitsubishi MR-J4-10A1-RJ (MR-J4-10A1-RJ) is an AC motion servo drive designed for industrial automation systems operating within the MELSERVO-J4 series. Engineered for precise motion control, this servo amplifier features high-speed SSCNET III/H communication capability, enabling synchronized multi-axis positioning and coordination with compatible Mitsubishi motion controllers. It includes an integrated dynamic brake and a built-in regenerative braking resistor, alongside dedicated compatibility with external safety units. Operating on a three-phase 380 to 480 V AC supply across the 400 V class (including 400, 415, and 440 V AC) or an alternative 283 to 340 V DC input, the drive delivers a rated output of 1000 W (1 kW) and a rated current of 2.8 A. The unit is housed in an IP20-rated protective enclosure suitable for clean control cabinet installations and is rated for operating ambient temperatures between 0 and +55 degrees Celsius. Additionally, it offers backward compatibility when deployed with the MR-J2S-[]B SSCNET conversion unit, making it an effective solution for machinery retrofits, packaging lines, material handling equipment, and CNC automated machinery.
