The Mitsubishi Electric MR-J4-200A is a single-axis servo amplifier belonging to the MELSERVO-J4 series, a line of general-purpose AC servo amplifiers designed for high-performance motion control applications. With a rated output of 2.0 kW, this servo amplifier is suitable for medium-power industrial automation tasks. It operates on a three-phase AC 200V power supply and features a general-purpose interface, making it compatible with a wide range of control systems.

The MR-J4-200A supports both position control via pulse train commands and speed/torque control through analog voltage commands. It is capable of handling a maximum command pulse frequency of 4 Mpulses/s, enabling high-speed and precise positioning. The amplifier is equipped with advanced vibration suppression technology, including algorithms that accommodate up to three inertia types, allowing it to simultaneously suppress low-frequency vibrations at two different points. This is particularly effective in reducing residual vibrations below 100 Hz that commonly occur in equipment such as robot arms or machine bodies.

Using the MR Configurator2 software, users can easily perform setup and tuning, optimizing performance for specific applications. The amplifier is also designed to improve trajectory accuracy in XY table systems, enhancing circular interpolation precision. Additionally, it effectively mitigates quadrant protrusion phenomena caused by friction and torsional forces when the servo motor changes direction, ensuring smoother and more accurate motion control.
