Mitsubishi Spindle Drive Unit MDS-B-SP-15

The Mitsubishi MDS-B-SP-15 is an AC spindle drive (controller) unit from the Mitsubishi MDS-B Series, controlling SJ-N series spindle motors with IGBT IPM sinusoidal wave PWM vector control in CNC machine tools. Direct replacement for a faulty MDS-B-SP-15; the MDS-A-SP-15 is the equivalent unit of the MDS-A Series.
