Mitsubishi MR-J4-700A4 Servo Drive for MELSERVO MR-J4 Series

The Mitsubishi MR-J4-700A4 (MR-J4-700A4) is an AC motion servo amplifier drive engineered for high-performance motion control within the Mitsubishi Electric MELSERVO MR-J4 series. Serving as a central motor drive component in automated machinery and production systems, the unit regulates power delivery to compatible AC servo motors to achieve rapid, highly accurate positioning, speed, and torque regulation. It includes a built-in dynamic brake as well as an integrated regenerative braking resistor, ensuring efficient deceleration and safe handling of regenerated energy during demanding duty cycles. Built for global deployment, this servo drive operates from a 400 V class three-phase power supply rated at 380 to 480 V AC (including 400, 415, and 440 V AC configurations). It delivers a rated output of 2,000 W (2 kW) with a rated current of 5.4 A. The drive features multi-network interface connectivity with PROFINET communication capabilities, and it is equivalent to the MRJ4200TM4PNT specification. Enclosed in an IP20-rated housing, the drive is engineered to operate reliably in ambient operating temperatures ranging from 0 to +55 degrees Celsius across motion control, packaging, material handling, and automated assembly installations.
