Mitsubishi MR-J4-15KA4-RJ Servo Amplifier for MELSERVO MR-J4 Series

The Mitsubishi MR-J4-15KA4-RJ (MR-J4-15KA4-RJ) is an AC servo amplifier drive designed for high-performance motion control within the Mitsubishi Electric MELSERVO MR-J4 series. Engineered for demanding machinery, this 400V class servo drive provides precise velocity, position, and torque regulation in motion systems requiring safety unit compatibility. The unit operates on a 380 V AC to 480 V AC three-phase power supply, supporting 400 V, 415 V, and 440 V AC nominal inputs, or an alternative 283 V DC to 340 V DC supply. It features integrated RS-422 and RS-485 serial communication interfaces for parameter configuration, networking, and drive diagnostics. Housed in an IP20-rated protective enclosure, the amplifier is rated for reliable operation within an ambient operating temperature range of 0 to +55 degrees Celsius. The drive supports an 11 kW rated output with a 32 A rated current, making it suitable for packaging equipment, material handling lines, CNC machine tools, and multi-axis production systems.
