Description

The Mitsubishi MR-J4-40B is a 0.4 kW AC servo amplifier in the MELSERVO-J4 series. The B-type interface connects over the SSCNET III/H fiber-optic motion network (150 Mbps) to Mitsubishi motion controllers and simple motion modules for deterministic multi-axis synchronization. Typical applications include machine tools, packaging and converting machinery, material handling, and other precision positioning axes paired with HG-series servo motors. This model has been discontinued by the manufacturer; it is supplied as replacement stock for installed J4 systems.

The MELSERVO-J4 platform features a 22-bit (4,194,304 pulse/rev) high-resolution encoder interface, 2.5 kHz speed frequency response, one-touch tuning, and advanced vibration suppression for fast, accurate motion.
