Mitsubishi HK-KT2034WBJWS AC Servo Drive Unit for MELSERVO MR-J4 Series

The Mitsubishi HK-KT2034WBJWS is an AC servo drive and amplifier unit belonging to the MELSERVO MR-J4 series. It is designed to be powered by an external converter unit and provides a rated output of 30 kilowatts with a rated current of 87 amperes in the 400-volt class. The drive features RS-422 and RS-485 communication interfaces and is compatible with dedicated safety units, enabling integration into safety-oriented machine architectures. It is considered equivalent to the MR-J4-DU30KA4-RJ ordering reference. The MELSERVO MR-J4 platform is widely used in high-performance motion control applications across CNC machine tools, semiconductor manufacturing equipment, packaging machinery and other automated production lines that demand precise and responsive servo control. The converter-fed topology allows multiple drive units to share a common DC bus, reducing component count and improving energy efficiency in multi-axis systems. The HK-KT2034WBJWS is a suitable replacement or spare part for systems originally equipped with this drive specification, helping to minimize downtime in demanding industrial environments.
