The MR-J4-200A+HG-SR202J is a matched servo amplifier and motor bundle from Mitsubishi's MR-J4 series, pairing the MR-J4-200A amplifier with the HG-SR202J medium-inertia, medium-capacity AC servo motor. Rated at 2.0 kW output with a rated current of 11.0 A, it delivers a maximum torque of 28.6 N·m and a rated speed of 2000 r/min, using sine-wave PWM current control.
Rated current of 11.0 A and maximum current of 31 A tell you the continuous and peak draw from the DC bus — size your power supply and wiring for the 11 A continuous, but make sure the bus can handle the 31 A surge during acceleration or stall. Maximum torque of 28.6 N·m at 2000 r/min gives you the muscle for applications like indexing tables or conveyor drives that need a hard shove without oversizing the frame. The amplifier uses a general-purpose interface (A type), so it accepts standard analog or pulse-train commands — no specialized motion controller required, just a common PLC with a pulse output or analog card.
