Mitsubishi MDS-D2-SP-400 Spindle Drive Unit

The Mitsubishi MDS-D2-SP-400 (MDS-D2-SP-400) is an industrial spindle drive unit developed for CNC machine tools and automated machining centers operating within the Mitsubishi MDS-D2 drive system. Engineered to provide precise speed and torque regulation for high-speed machine spindles, this unit ensures stable cutting performance and dependable motor synchronization during heavy-duty cutting and milling cycles. Operating within the 200 V class, the drive accepts a 200 V AC to 230 V AC three-phase input or a 270 V DC to 311 V DC power bus input, delivering a rated output current of 174 A to the connected spindle motor. The unit features an IP20 protection rating to shield internal power electronics and control circuitry against solid foreign objects. It is rated for reliable continuous operation in ambient operating temperatures ranging from 0 to +55 degrees Celsius. The MDS-D2-SP-400 serves as a critical component in multi-axis CNC systems, including turning machines, milling centers, and automated manufacturing cells, maintaining consistent spindle velocity and rapid acceleration and deceleration profiles.
