It communicates over SSCNET III/H — Mitsubishi's high-speed motion bus — and runs full closed-loop control, meaning the encoder feedback is used for both commutation and position/velocity regulation, not just motor phasing. The 1 kW output rating governs the motor it can drive — pair it with a Mitsubishi HG-JR or HG-SR servo motor of the same power class. The single-phase 200 VAC input means it draws from a standard industrial line; no step-down transformer needed for 200 V class systems. SSCNET III/H is a fiber-optic motion network with deterministic cycle times down to 0.222 ms, so this drive integrates natively into a Mitsubishi motion chain without a protocol gateway.","metaTitle":"Mitsubishi MR-J4-100B-RJ MELSERVO J4 Servo Drive, 1 kW, 200","metaDescription":"MR-J4-100B-RJ MELSERVO J4 servo drive by Mitsubishi. 1 kW rated output, 1-phase 200 VAC input, SSCNET III/H interface, full closed-loop control.
