Product Overview
The MR-J2S-70B is a Mitsubishi Electric general-purpose AC servo amplifier from the MELSERVO-J2S (MR-J2S-B) family. It accepts three-phase 200-230 VAC (50/60 Hz) or single-phase 230 VAC input and provides closed-loop PWM current control to drive compatible HC/HA servo motors. In a control system, this amplifier modulates motor torque and speed, providing protection functions and interfaces for motion control. Applications typically include machine tools, assembly lines, robotics, and packaging machinery where precise motion control is required.
Best Suited For
- Mid-power servo control for HC/HA series motors
- Machines requiring 200-230 VAC single or three-phase input
- Applications needing built-in protection (overcurrent, overspeed, regeneration)
- Installation in IP00 indoor environments where forced-cooling is acceptable
