Mitsubishi MDS-D2-SP2-4040S Dual-Axis Spindle Drive Unit for MDS-D2 Series

The Mitsubishi MDS-D2-SP2-4040S (MDS-D2-SP2-4040S) is a dual-axis slim-type spindle drive unit engineered for high-performance CNC machine tool applications utilizing the Mitsubishi MDS-D2 drive series. Operating as a compact two-axis spindle controller, this unit delivers independent spindle control across axis A and axis B, supporting modern multi-spindle machining configurations while conserving cabinet enclosure space. The drive unit is rated for an output current of 10 A on axis A and 10 A on axis B. It operates with a rated supply voltage of 200 V AC to 230 V AC (200 V class, 220 V AC or 230 V AC) via three-phase AC input, or alternatively with a 270 V DC to 311 V DC direct current input. Built with an IP20 degree of protection, the module is engineered for reliable installation within industrial control cabinets and is rated for ambient operating temperatures ranging from 0 to +55 degrees Celsius. The unit provides precise spindle acceleration, deceleration, and speed regulation in automated milling, turning, and machining centers driven by Mitsubishi CNC controllers.
