Product Overview

The MR-J2S-200A is a servo amplifier from Mitsubishi's MELSERVO-J2S family. It provides position, speed, and torque control for compatible Mitsubishi AC servo motors (e.g., HC-RFS series up to 2.0 kW). The unit accepts a 3-phase 200-230 VAC, 50/60 Hz supply, and includes a built-in dynamic brake and protective features like overcurrent and overvoltage shut-off. It is a legacy model (introduced in 1999, discontinued in 2015) commonly used in mid-range precision motion control applications including machine tools, packaging, and pick-and-place systems. MR-J2S-200A is notable for its compact footprint, approximately 2.3 kg, and sine-wave PWM current control scheme.
