Mitsubishi MR-J4-60A4-RJ AC Servo Amplifier Drive for MELSERVO MR-J4 Series

The Mitsubishi MR-J4-60A4-RJ (MR-J4-60A4-RJ) is an AC servo amplifier drive engineered for high-performance motion control within the Mitsubishi MELSERVO MR-J4 product family. Designed to deliver reliable speed, position, and torque control for industrial machinery, this drive is compatible with MR-J4 series servo systems across diverse manufacturing and automated assembly applications. This unit features a built-in dynamic brake and an integrated braking resistor, alongside full compatibility with external safety units to protect personnel and machinery. Operating on a 400 V class power system, the drive accepts a 380 V to 480 V AC three-phase supply (including 400 V, 415 V, and 440 V AC nominal ratings) or a 283 V to 340 V DC direct input. Built with an IP20 ingress protection rating, the amplifier operates reliably in ambient operating temperatures ranging from 0 to +55 degrees Celsius. With its integrated SSCNET III/H communication capability, the MR-J4-60A4-RJ ensures rapid, synchronized networking with motion controllers for complex packaging, processing, and multi-axis positioning equipment.
