Mitsubishi HK-KT2034WK AC Servo Drive Unit for MELSERVO MR-J4 Series

The Mitsubishi HK-KT2034WK is an AC servo drive and amplifier unit belonging to the MELSERVO MR-J4 series. It delivers a rated output of 30 kilowatts with a rated current of 174 amperes and operates in the 200-volt class. Power is supplied through a separate converter unit, making this a drive-only configuration. The unit features SSCNET III/H fiber-optic communication capability for high-speed, noise-resistant data exchange with compatible motion controllers and is considered equivalent to the MR-J4-DU30KB-RJ order code. Designed with built-in safety unit compatibility, the HK-KT2034WK supports functional safety architectures without requiring additional external safety modules. It is intended for use in high-performance motion control applications such as CNC machine tools, automated production lines, and precision positioning systems where the MELSERVO MR-J4 platform is deployed. The converter-fed topology allows multiple drive units to share a common DC bus, simplifying system wiring and improving energy efficiency in multi-axis installations.
