Mitsubishi MR-J4-700TM-PNT Servo Amplifier for MELSERVO MR-J4 Series

The Mitsubishi MR-J4-700TM-PNT (MR-J4-700TM-PNT) is an AC motion servo amplifier engineered for the Mitsubishi Electric MELSERVO MR-J4 series. Serving as a high-performance drive unit in automated machinery, it provides precise motor control and dynamic motion regulation for industrial motion systems. The unit operates from a three-phase 380 V to 480 V AC supply (400 V class, including 400 V, 415 V, and 440 V AC) and delivers a rated output of 22 kW with a rated current of 63 A. Designed for reliable operation within control cabinets, the amplifier features an IP20 ingress protection rating and is rated for ambient operating temperatures ranging from 0 to +55 degrees Celsius. It incorporates built-in RS-422 and RS-485 serial communication capabilities for integration, configuration, and monitoring within multi-axis motion networks. Functionally equivalent to the MRJ422KA4 unit, this drive is deployed across automated manufacturing lines, multi-axis positioning systems, and precision industrial machinery requiring dependable speed and torque regulation.
