⚙️ What It Does

This amplifier:

• Drives three servo motors simultaneously
• Controls:
  • Position
  • Speed
  • Torque
• Ensures precise synchronized motion across axes
• Communicates with CNC via fiber optic (FSSB)

👉 Simple explanation:
One amplifier controls 3 medium-power CNC axes together.

🔍 6117 Series Advantage

Compared to older 6114 models:

• ✔ Improved efficiency and thermal design
• ✔ More compact and reliable
• ✔ Better heat dissipation
• ✔ Same multi-axis concept (3-in-1 amplifier)

---

🏭 Applications

• CNC machining centers
• CNC milling machines
• Medium-load multi-axis systems
• Industrial automation requiring synchronized motion

Typical axes:

• X, Y, Z axes in standard machining centers

---

🔑 Key Features

• ✔ 3-axis integrated amplifier (space saving)
• ✔ 20/20/20 rating → equal medium load per axis
• ✔ High precision positioning
• ✔ Built-in diagnostics and protection
• ✔ Compatible with αi servo motors

---

⚠️ Important Notes

• H303 = 3-axis module (SVM3 type)
• “20/20/20” = equal power on all three axes
• Requires:
  • Power supply module (PSM)
  • Matching αi servo motors
• Often serviced/repaired instead of replaced
