The Mitsubishi MR-J4-200A-RJ is a servo amplifier in the MR-J4 series, delivering 2 kW rated output from a single-phase 200 VAC supply. It supports full closed-loop control, meaning the drive continuously compares the encoder feedback against the commanded position and corrects in real time — essential for applications where load disturbances or mechanical backlash would otherwise cause position error.
Integration Notes
Rated for general-purpose interface use, so it accepts standard step/direction or analog speed/torque commands without a dedicated fieldbus module. The single-phase 200 VAC input simplifies panel wiring in regions where three-phase is unavailable, but the 2 kW output still drives a moderate servo motor — sized for a small indexing axis or a pick-and-place arm. Full closed-loop control means the encoder cable must be shielded and routed separate from power wiring to avoid noise injection into the feedback loop.
