📌 What the “W” means

The “W” version in Mitsubishi MDS-EH drives generally indicates:

• Higher capacity / reinforced power stage
• Increased thermal handling (more heat dissipation)
• Used for more demanding axis loads compared to standard V1-80

So:

• V1-80 → standard heavy axis
• V1-80W → upgraded heavy-duty version

📊 Series Position

Within V1 axis drives:

• V1-10 / V1-20 → light duty
• V1-40 → medium duty
• V1-80 → heavy duty
• V1-80W → heavy duty + enhanced thermal/power margin
• V1-160 / V1-160W → ultra heavy industrial axes
