⚙️ What It Does

This amplifier:

• Drives 3 servo motors simultaneously
• Controls:
  • Position
  • Speed
  • Torque
• Provides synchronized multi-axis motion
• Communicates with CNC via fiber optic link (FSSB)

👉 Simple explanation:
One compact amplifier controls 3 small-capacity servo axes.

🔍 6117 vs 6114 Series (Important)

• 6117 series = newer / improved version of 6114
• Better:
  • Thermal performance
  • Efficiency
  • Compact design
• Same concept:
  • Multi-axis integrated servo amplifier

---

🏭 Applications

• CNC machines with low-power axes
• Compact machining centers
• Small automation systems
• Light-duty motion control applications

Typically used for:

• X, Y, Z axes in smaller machines
• Auxiliary axes (tool changers, feeders, etc.)

---

🔑 Key Features

• ✔ Triple-axis (3-in-1) amplifier
• ✔ Compact and space-saving
• ✔ Energy-efficient (improved over 6114)
• ✔ Built-in diagnostics and protection
• ✔ Works with αi series servo motors

---

⚠️ Important Notes

• H301 = 3-axis model
• “4/4/4” = low current rating (light load axes)
• Requires:
  • Matching power supply module (PSM)
  • Compatible αi motors
• Typically repaired rather than replaced
