What it is and what it does
The MR-JE-200A+HG-SN202J: This is a Mitsubishi MR-JE-_A servo amplifier paired with an HG-SN202J AC servo motor — a combined 2.0 kW rated output system. Control is sine-wave PWM current control, so it drives the motor smoothly across the speed band. Rated current sits at 11.0 A, with a maximum torque cap of 28.6 N·m at 2000 r/min. The motor includes an oil seal (J suffix), making it a better fit for wet or dusty environments where chips or coolant might hit the shaft.
Wiring and panel fit
The amplifier uses a general-purpose interface (type A), so you get the common pulse-train and analog inputs you'd expect. Motor is medium inertia, medium capacity, built for three-phase 200 V AC. Keep the oil seal on your mind when routing the cable gland — it's there to keep contaminants out of the bearing.
