The MR-JE-70A+HG-KN73J-S100 is a Mitsubishi servo system pairing the MR-JE-_A servo amplifier with an HG-KN73J-S100 AC servo motor. Rated output is 0.75 kW at 3000 r/min, which covers positioning and speed control for small-axis applications like pick-and-place, labeling, and conveyor indexing where the load inertia is low and the cycle time is tight. The motor carries the J oil seal suffix, meaning it's built for environments where oil mist or splash is present — a common requirement on machining centers and packaging lines where lubrication mist is unavoidable. The amplifier uses a general-purpose interface (A type), so it accepts standard pulse-train or analog speed/torque commands from a motion controller or PLC without needing a dedicated fieldbus card.
Integration notes
The HG-KN73J-S100 motor is a low-inertia, small-capacity design. That means it accelerates and decelerates quickly, but it also means the load-to-motor inertia ratio needs to stay within the drive's tuning range — typically under 10:1 for stable gain. Oversizing the motor for a high-inertia load defeats the purpose of this series.
