Description
The MITSUBISHI MDS-EH-CV-370 is a Spindle Drive Unit belonging to the MDS-E/EH Series of CNC drives, specifically designed for MAZAK CNC machine tools (e.g., Mazak Integrex, Nexus, Variaxis series). This 370V, 55kW (or 75HP) drive is responsible for controlling the main spindle motor, providing precise speed regulation, rigid tapping capability, and high-torque output for heavy-duty machining operations. It is a critical component in Mazak’s Mitsubishi-based CNC systems, often paired with MDS-EH-SP spindle amplifiers and Mitsubishi MDS-EH-ECT expansion control units.
