Mitsubishi M80 Spindle Drive 400V MDS-E-SP-240

The Mitsubishi MDS-E-SP-240 is a high-capacity 1-axis CNC spindle drive unit from Mitsubishi Electric’s MDS-E series, designed to control Mitsubishi SJ-series AC spindle motors in heavy-duty CNC machining applications.

It is a spindle amplifier/drive, not a motor.

Key Specifications (MDS-E-SP-240)

The MDS-E series includes spindle orientation, rigid tapping, spindle/C-axis control, and high-response acceleration/deceleration functions for CNC machining systems.

Features

• Designed for Mitsubishi SJ-series spindle motors
• High-capacity spindle control for heavy machining loads
• Stable torque and spindle speed regulation
• Supports spindle orientation and rigid tapping
• Compact modular CNC drive design
• Forced-air cooling for continuous-duty industrial operation

Typical Applications

• Large CNC machining centers
• Heavy-duty milling machines
• CNC turning and boring machines
• Metal cutting and forming systems
• Industrial CNC automation equipment

Compatible Motor Examples

The MDS-E-SP-240 is commonly paired with higher-capacity Mitsubishi spindle motors such as:

• SJ-4-V18.5 series
• SJ-4-V22 series
• SJ-4-V26 series
• SJ-4-V37 series

Motor compatibility depends on spindle load, acceleration requirements, and machine configuration.
