⚙️ Key Technical Details

• Type: AC Servo Amplifier
• Series: Alpha i (αi) – 6114
• Variant: C-type (compact design)
• Axes: 3 axes (triple-axis)
• Model: SVM3-20/20/40i
• Current Rating:
  • Axis 1 → 20A
  • Axis 2 → 20A
  • Axis 3 → 40A (higher power axis)
• Communication: FSSB (fiber optic servo bus)

⚙️ What “C304” Means

• C = Compact / integrated version
• 304 =
  • 3-axis module (SVM3)
  • Mixed power rating (20/20/40)

👉 Equivalent to:

• H304 (same ratings, standard size module)

---

⚙️ What It Does

This amplifier:

• Drives three servo motors simultaneously
• Controls:
  • Position
  • Speed
  • Torque
• Handles uneven load distribution (one axis higher power)
• Synchronizes multi-axis motion via CNC commands

👉 Simple explanation:
Compact amplifier controlling 3 axes where one axis needs more power.

---

🏭 Applications

• CNC machining centers
• Vertical machining centers (VMC)
• Machines where:
  • X, Y → medium load
  • Z → heavier load (gravity / spindle head)

Also used in:

• Automation systems with mixed axis loads

---

🔍 Key Features

• ✔ 3-axis integrated amplifier
• ✔ Compact design (C-type)
• ✔ Mixed rating (20/20/40)
• ✔ High precision control
• ✔ Fiber optic communication (FSSB)
• ✔ Compatible with αi servo motors

---

⚠️ Important Notes

• C304 = compact version of H304
• Same functionality, smaller footprint
• Requires:
  • Proper power supply module (PSM)
  • Matching servo motors
• Commonly repaired/refurbished
