Mitsubishi MR-J4CBL20-CN3-3M-EG AC Servo Drive for MELSERVO MR-J4

The Mitsubishi MR-J4CBL20-CN3-3M-EG (MR-J4CBL20-CN3-3M-EG) is an AC motion servo amplifier designed for high-performance motion control within the MELSERVO MR-J4 series. Built to deliver precise motor control in automated machinery, this drive features an integrated dynamic brake and a built-in regenerative braking resistor to ensure rapid stopping and efficient energy dissipation during deceleration cycles. It also offers compatibility with optional safety units to support functional safety standards in industrial motion applications. Operating on a three-phase supply voltage of 380 V AC to 480 V AC (400 V class rated at 400 V, 415 V, or 440 V AC) or a 283 V DC to 340 V DC bus input, the unit delivers a rated output of 3500 W (3.5 kW) with a rated current of 8.6 A. Communication is supported through RS-422 and RS-485 serial interfaces for configuration and diagnostic monitoring. The amplifier has an IP20 degree of protection and is rated to operate in ambient operating temperatures ranging from 0 °C to +55 °C. Functionally equivalent to MRJ4350A4RJJ001, it is used across industrial manufacturing, packaging, and automated positioning systems.
