Mitsubishi MR-J4-200B-RJ020 Servo Amplifier, 2 kW, SSCNET II

The MR-J4-200B-RJ020: The 2 kW output matches a servo motor in that power class — typical for medium-inertia loads like conveyors, rotary tables, or winding sections on a paper machine. The 1-phase 200 VAC input means it connects to a standard single-phase line, not a three-phase supply, which simplifies installation in smaller panels or retrofit jobs where three-phase isn't available. SSCNET III/H is Mitsubishi's proprietary high-speed synchronous network. It daisy-chains multiple drives back to a motion controller with deterministic cycle times. If your existing line uses SSCNET III or III/H, this amplifier drops in without a protocol converter. Full closed-loop control means the drive reads a separate encoder on the load (not just the motor) — essential for applications where backlash or mechanical compliance must be compensated, such as a ball-screw axis on a converting machine.
