Mitsubishi MR-J4-700B-RJJ001 AC Servo Amplifier for MELSERVO MR-J4 Series

The Mitsubishi MR-J4-700B-RJJ001 (MR-J4-700B-RJJ001) is an AC motion servo amplifier designed for high-performance motion control within the Mitsubishi Electric MELSERVO MR-J4 family. Built to deliver precise position, speed, and torque control, this servo drive features integrated SSCNET III/H optical communication capability, enabling high-speed synchronous motion networking and real-time data transmission with compatible system controllers. The unit incorporates a built-in dynamic brake and an integrated braking resistor to provide effective deceleration and energy dissipation during demanding dynamic cycles. Additionally, it offers safety unit compatibility to support functional safety standards across complex automation architectures. Engineered for industrial environments, the drive operates with an input supply voltage of 200 to 240 V AC (200 V class) or 283 to 340 V DC, supporting single-phase two-pole, three-phase three-pole, or direct-current power configurations. It is housed in an IP20-rated enclosure and rated for ambient operating temperatures ranging from 0 to +55 degrees Celsius. The Mitsubishi MR-J4-700B-RJJ001 is ideally suited for multi-axis machinery, packaging systems, material handling equipment, and computerized numerical control systems requiring dependable synchronization and rapid response.
