The amplifier (MR-J4-500A) uses sine-wave PWM current control and delivers a rated current of 28.0 A, with a maximum current of 70 A. The motor (HG-SR502J) is a medium-inertia, medium-capacity AC servo motor rated at 5.0 kW output, with a rated speed of 2000 r/min and a maximum torque of 71.6 N·m. The 'J' suffix on the motor indicates it includes an oil seal, making it suitable for applications where lubricant ingress is a concern — common in machine tool spindles or gearbox-coupled axes. The 5.0 kW rated output and 2000 r/min rated speed define the continuous-duty envelope: the motor can deliver 5.0 kW at 2000 r/min continuously. The 71.6 N·m maximum torque is available for acceleration and deceleration — critical for sizing the amplifier's peak current capability (70 A) to match the load inertia. The 28.0 A rated current on the amplifier side sets the continuous supply requirement. For a 400 V three-phase line, this corresponds to roughly 19 kVA apparent power. The sine-wave PWM control method keeps torque ripple low, which matters for contouring accuracy in CNC or robotic axes. The general-purpose interface (A) means the amplifier accepts standard analog command signals (typically ±10 V or 4-20 mA) and encoder feedback — no proprietary fieldbus card required for basic speed/torque control.","metaTitle":"Mitsubishi MR-J4-500A+HG-SR502J Servo System, 5.0 kW, 28.0 A","metaDescription":"Mitsubishi MR-J4-500A+HG-SR502J servo amplifier with HG-SR502J motor. 5.0 kW rated output, 28.0 A rated current, 71.6 N·m max torque, 2000 r/min rated speed.
