The Mitsubishi MR-J3W-22B is a two-in-one integrated servo amplifier belonging to the MELSERVO-J3W series, designed for dual-axis control within a single compact unit. Each axis—A and B—delivers a rated output of 200W, making it suitable for applications requiring synchronized or independent control of two servo motors.

This servo amplifier features an SSCNET III fiber-optic communication interface, ensuring high-speed, noise-immune data transmission between the amplifier and the controller. It shares the same multifunctionality and practical performance as the standard MR-J3-B series servo amplifiers, offering flexibility in motor type selection. The MR-J3W-B can control any combination of two motors, including rotary servo motors, linear servo motors, and direct-drive servo motors.

Compared to using two separate MR-J3-B amplifiers, the MR-J3W-22B reduces installation space by 17% to 25%, enabling the design of more compact control cabinets and machinery. Additionally, both axes share a common main circuit power supply, control circuit power supply, and SSCNET III fiber-optic communication line. This shared architecture significantly reduces wiring complexity, lowers component count, and simplifies maintenance, ultimately contributing to a more streamlined and cost-effective system integration.
