Matched pair – amplifier plus motor
The MR-JE-70A+HG-SN152J: This is the factory-matched combination of a Mitsubishi MR-JE-70A servo amplifier and an HG-SN152J AC servo motor. The set avoids the guesswork of pairing separate units – the drive parameters and feedback tuning are pre-configured for the motor's medium-inertia, 2000-r/min frame.
What the ratings tell you
Rated output is 1.5 kW, which covers typical point-to-point positioning axes on packaging, pick-and-place, or light assembly machines. The peak torque of 21.5 N·m is what gets you through a short acceleration or tight move – the continuous rated current of 5.8 A is the thermal limit for steady duty. Maximum current of 29 A is the hardware ceiling, but that's short-term only. The J oil-seal suffix on the motor means it's built for environments with splashing oil or coolant; skip the oil-seal variant if the application is dry.
