Mitsubishi MR-J4-700B-RJ010 Servo Amplifier MELSERVO MR-J4

The Mitsubishi MR-J4-700B-RJ010 (MR-J4-700B-RJ010) is an AC servo motion drive engineered for high-precision industrial automation within the MELSERVO MR-J4 series. Equipped with high-speed SSCNET III/H optical network communication, this servo amplifier enables synchronous multi-axis motion control with minimal transmission delay and high noise immunity across automated machinery. The unit incorporates dynamic braking and a built-in regenerative braking resistor to deliver reliable motor deceleration and effective energy dissipation during cycling operations. Compatible with dedicated safety units, the MR-J4 architecture supports advanced machine safety integration while preserving production uptime. Designed for versatile industrial installations, the drive supports AC supply inputs in the 200 to 240 V AC range across 50/60 Hz single-phase or three-phase systems, as well as 283 to 340 V DC bus connections. With an IP20 degree of protection, the servo amplifier operates reliably within ambient operating temperatures ranging from 0 to +55 degrees Celsius. It serves demanding automation setups including packaging machinery, machine tools, material handling gantries, and converting equipment requiring responsive and deterministic servo performance.
