🏭 Typical Applications

• Large CNC machining centers
• Heavy-duty axis drives (X/Y/Z or rotary axes)
• High-load milling and turning machines
• Industrial robotics requiring high torque
• Precision automation systems with high inertia loads

📌 Position in the Series

Within the MDS-EH V1 lineup:

• V1-10 → light duty axis
• V1-20 / V1-40 → medium duty
• V1-80 → high torque / heavy axis drive
• V1-160 / V1-200 → ultra heavy industrial axes

⚠️ Important Note

The MDS-EH-V1-80 is not a general-purpose servo drive. It is tightly integrated with:

• Mitsubishi CNC controllers (M70 / M700 / etc.)
• Mitsubishi servo motors
• Dedicated optical communication systems

So compatibility is system-based, not universal.
