• DC bus input: ~513–648V DC
• Control power supply: 380–480V AC, 50/60Hz
• Motor control: Fully digital closed-loop servo control
• Encoder feedback: Mitsubishi high-resolution servo encoder support
• Safety functions: STO and CNC-integrated protection/diagnostics
• Installation: Cabinet-mounted, forced ventilation required

📌 The MDS-EH series is part of Mitsubishi’s high-performance CNC drive system, designed for high-speed, high-accuracy motion control with improved processing and communication speed.

🏭 Typical Applications

• Large CNC machining centers
• Heavy feed axes (X/Y/Z on big machines)
• High-load lathes and milling machines
• Industrial robotics with high torque demand
• Precision automation systems

📊 Position in V2 Series

• V2-10 → light duty
• V2-20 → light/medium duty
• V2-40 → medium duty
• V2-80 → heavy-duty dual-axis drive
• V2-160 → extra heavy-duty systems

⚠️ Important Notes

• Not a universal servo drive (only works in Mitsubishi CNC ecosystems)
• Requires matching Mitsubishi CNC controller (M70 / M700 class)
• Must be paired with compatible Mitsubishi servo motors + encoder system
• Needs proper cabinet cooling due to high power density
