Mitsubishi MR-J4-10B-RJ010 AC Servo Amplifier Drive for MELSERVO-J4

The Mitsubishi MR-J4-10B-RJ010 (MR-J4-10B-RJ010) is an AC motion servo amplifier drive designed for high-performance motion control within the Mitsubishi Electric MELSERVO-J4 series. Engineered for precision automated machinery, this servo drive features a built-in dynamic brake and an integrated regenerative braking resistor, providing reliable deceleration and energy dissipation during dynamic industrial operations. It also offers compatibility with external safety units to protect personnel and production equipment. The unit operates from a 200 to 240 V AC supply voltage across 200 V class configurations, including 220 V and 230 V AC, or from a 283 to 340 V DC bus voltage. It supports flexible power input configurations including single-phase, three-phase, or direct DC input. Delivering a rated output power of 1,000 W (1 kW) with a rated current of 6 A, the amplifier integrates CC-Link communication capability for seamless networking within Mitsubishi motion architectures. Built with an IP20 degree of protection, the drive is rated for ambient operating temperatures ranging from 0 to +55 degrees Celsius. It serves as an equivalent replacement for MRJ4100GFKS units in automated manufacturing, robotics, and multi-axis machinery.
