Mitsubishi MR-J4-700A4-RJ AC Servo Amplifier for MELSERVO MR-J4 Series

The Mitsubishi MR-J4-700A4-RJ (MR-J4-700A4-RJ) is an advanced AC motion servo amplifier drive designed for high-performance motion control within the Mitsubishi Electric MELSERVO-J4 series. Equipped with a versatile multi-network interface featuring EtherNet/IP communication capability, this servo amplifier integrates seamlessly into modern networked machine architectures. It delivers a rated output of 2,000 watts (2 kW) and a rated output current of 11 A, operating reliably with a power supply voltage of 200 to 240 V AC across 200 V class systems. The unit supports both single-phase two-wire and three-phase three-wire AC input configurations. For enhanced operational reliability and dynamic stopping control, the drive incorporates a built-in dynamic brake and an integrated regenerative braking resistor. Designed for control cabinet installation, it provides an IP20 ingress protection rating and is rated for operation across ambient temperatures from 0 to +55 degrees Celsius. This servo drive is equivalent to the MRJ4200TMEIP configuration and is widely utilized in packaging equipment, assembly machinery, and automated production systems requiring precise speed, torque, and positioning control.
