Mitsubishi HK-KT2034WJ AC Servo Drive Unit for MELSERVO MR-J4 Series

The Mitsubishi HK-KT2034WJ (HK-KT2034WJ) is an AC servo motion drive and amplifier unit belonging to the MELSERVO MR-J4 series. This drive unit features compatibility with safety units and receives its power supply from a dedicated converter unit, making it suitable for multi-axis configurations where a centralized power architecture is required. It is considered equivalent to the Mitsubishi MR-J4-DU30KB4-RJ. The MELSERVO MR-J4 series is widely used in high-performance servo applications across CNC machinery, packaging equipment, semiconductor manufacturing, and general factory automation. By separating the power conversion stage from the drive stage, this unit allows for a compact installation footprint and simplified wiring in multi-axis systems. The HK-KT2034WJ is a direct replacement spare part for systems originally equipped with this drive unit, ensuring continued machine uptime and reliable motion control performance.
