⚙️ Key Specifications

• Axis rating: 2-axis servo amplifier
• Current class: ~80A class (high-power V2 segment)
• DC bus input: 513–648V DC
• Control power supply: 380–480V AC, 50/60Hz
• Heat dissipation: higher than standard V2-80 due to reinforced design
• Encoder feedback: Mitsubishi high-resolution servo encoder system
• Functions: STO safety, regenerative braking support, CNC diagnostic integration

📌 The “W” version is a reinforced/high thermal capacity variant, designed for more demanding continuous load operation compared to standard V2-80.

🏭 Typical Applications

• Large CNC machining centers
• Heavy feed axes (X/Y/Z on big machines)
• High-torque industrial automation systems
• Gantry and multi-axis precision machines
• Heavy-duty lathes and milling systems

📊 Position in V2 Series

• V2-10 → light duty
• V2-20 → light/medium duty
• V2-40 → medium duty
• V2-80 → heavy duty
• V2-80W → heavy duty + enhanced thermal/power margin
• V2-160 → extra heavy duty

⚠️ Important Notes

• Not a standalone drive → works only with Mitsubishi CNC controllers (M70 / M700 / etc.)
• Must be paired with compatible Mitsubishi servo motors + encoder system
• Cabinet cooling and correct grounding are critical due to high power level
• “W” models are often used where standard 80A units run near thermal limits
