Mitsubishi MR-J4-700GF Servo Amplifier for MELSERVO MR-J4 Series

The Mitsubishi MR-J4-700GF (MR-J4-700GF) is an AC servo amplifier designed for high-performance motion control within the Mitsubishi MELSERVO MR-J4 series. Engineered for industrial automation machinery, this servo drive provides precise motor control, high-speed responsiveness, and reliable operation across automated manufacturing environments. The unit incorporates a built-in dynamic brake and an integrated braking resistor to handle regenerative energy effectively during rapid deceleration cycles. In addition, it offers full compatibility with functional safety units to support safe machine operation. The servo amplifier is designed to operate on a 200 V to 240 V AC supply voltage (or 283 V to 340 V DC bus voltage) with single-phase, three-phase, or direct current input options. It features communication capability, including SSCNET III/H networking for synchronized multi-axis motion architectures. Housed in a compact enclosure with an IP20 ingress protection rating, the device is rated for ambient operating temperatures between 0 and 55 degrees Celsius. The MR-J4-700GF is widely deployed in production lines, packaging equipment, material handling systems, and CNC machine tools requiring dependable servo drive performance.
