Mitsubishi MR-J4-10GF-RJ 1kW AC Servo Amplifier for MELSERVO-J4

The Mitsubishi MR-J4-10GF-RJ (MR-J4-10GF-RJ) is an advanced AC motion servo drive from the MELSERVO-J4 series, engineered for high-precision industrial motion control applications. This drive operates on a three-phase 380 to 480 VAC power supply (400 V class) and provides a rated output power of 1,000 W (1 kW) with a rated current of 2.8 A. It features a multi-network interface with EtherCAT communication capability, enabling seamless integration into modern real-time automated motion networks and industrial architectures. Equipped with an integrated dynamic brake and a built-in braking resistor, the MR-J4-10GF-RJ ensures rapid deceleration and controlled energy dissipation during complex positioning tasks. The unit carries an IP20 protection rating and is rated to operate reliably within an ambient temperature range from 0 to +55 degrees Celsius. It is also equivalent to model reference MRJ4100TM4ECT. This servo amplifier is widely utilized across packaging machinery, CNC handling systems, assembly equipment, and coordinated multi-axis production lines requiring fast response and dependable continuous duty.
