Mitsubishi MDS-D2-SP2-4020 Dual-Axis Spindle Drive Unit for MDS-D2 Series

The Mitsubishi MDS-D2-SP2-4020 (MDS-D2-SP2-4020) is a dual-axis spindle drive unit engineered for use with Mitsubishi CNC machinery and MDS-D2 series multi-axis drive systems. This high-performance spindle controller independently drives two spindle motors from a single compact unit, providing coordinated speed and torque control for demanding machining operations. It features a rated output current of 10 A on Axis A and 4.5 A on Axis B, delivering optimized power distribution across dual-spindle CNC configurations. The unit supports an input supply voltage of 200 to 230 V AC (200 V class, 220/230 V AC) or 270 to 311 V DC, accommodating three-phase AC or DC bus power architectures. Built with an IP20 degree of protection, the drive operates reliably in ambient industrial operating temperatures ranging from 0 to +55 degrees Celsius. The MDS-D2-SP2-4020 is widely deployed in precision CNC lathes, milling machines, and multitasking machine tools, enabling synchronized spindle operations and high-speed cutting while minimizing cabinet footprint.
