Description
The Mitsubishi MDS-EH-V2-20 is a 2-axis CNC AC servo drive (servo amplifier) from the MDS-EH series, used in Mitsubishi CNC machine tool systems for precision motion control.
š§ Description
- Product type: 2-axis servo drive / servo amplifier
- Series: MDS-EH
- Model: MDS-EH-V2-20
- Manufacturer: Mitsubishi Electric
- Application: CNC machining centers, lathes, milling machines, robotics, and industrial automation
- Axis configuration: Dual-axis (L/M or X/Y type axes depending on machine layout)
- Control method: High-speed sine-wave PWM servo control
- System type: CNC DC-bus servo drive system
- Cooling: Forced-air cooling (cabinet mounted)
- Protection: IP20 industrial enclosure use only
āļø Key Specifications
- Axis rating: 2-axis integrated servo amplifier
- Current class: 20A class per axis (V2-20 rating level)
- DC bus input: ~513ā648V DC
- Control power supply: 380ā480V AC, 50/60Hz
- Control type: Fully digital closed-loop servo control
- Feedback: Mitsubishi high-resolution servo encoder support
- Safety functions: STO / brake control supported (EH series feature set)
- Communication: Optical link to CNC controller system
š The MDS-E/EH series is designed for high-speed, high-accuracy CNC motion control with improved processing speed and servo response performance.
š Typical Applications
- CNC machining centers (small to medium size machines)
- Light-to-medium feed axes (X/Y/Z axes)
- Precision lathes and milling machines
- Industrial robotics (moderate load axes)
- Automated production systems
š Position in V2 Series
- V2 = 2-axis integrated drive module
- V2-10 ā light duty
- V2-20 ā light/medium duty (more torque than V2-10)
- V2-40 ā medium duty
- V2-80 / V2-160 ā heavy duty industrial axes
ā ļø Important Notes
- Not a standalone servo drive ā only works with Mitsubishi CNC controllers (M70 / M700 / etc.)
- Must be matched with Mitsubishi servo motors + encoder system
- Not interchangeable with general-purpose drives (like MR-J series)
- Designed for cabinet installation with proper cooling and grounding
