Mitsubishi Electric MR-J2S-70A Servo Drive Module

The Mitsubishi Electric MR-J2S-70A servo drive amplifier delivers precise, closed-loop motion control for servo motors in CNC machines, robotic systems, packaging equipment, and automated conveyors, providing 750 W of output power from a 200-230 VAC supply (1-phase or 3-phase) at 50/60 Hz. It uses a PWM/current-control scheme with encoder feedback for accurate speed, torque, and position, and includes built-in dynamic braking and a parameter configuration interface. The drive is designed for panel-mount installation and is cooled by a built-in fan. Operating temperature range is 0 °C to 50 °C with storage from -20 °C to 65 °C. Protection features cover overcurrent, overvoltage, overheat, and fault conditions, and the unit exposes encoder feedback and I/O control terminals for integration with Mitsubishi AC servo motor series. Common replacements for this model include Mitsubishi MR-J4-70A, MR-JE-70A, and SGDV-R70A01A.
