Description
🔧 Fanuc A06B-6127-H207 Servo Amplifier – Description
The A06B‑6127‑H207 is a servo amplifier module from FANUC, belonging to the Alpha i servo drive family. It is designed for use in CNC (Computer Numerical Control) machines and industrial motion control systems.
đź“Ś Official / Practical Description
- Type: Dual‑axis servo amplifier module
- Series: FANUC A06B‑6127
- Model: AiSV‑40/40HV
- Application: High‑voltage servo drive for CNC motion control
- Axes Controlled: 2 axes (dual channel)
- Voltage Class: High Voltage (typically ~400 V AC)
- Current Output: ~9.1 A per axis (typical spec)
- Max Output Voltage: ~480 V AC
đź“Ś This amplifier is part of the Alpha i series servo drives, often used with FANUC CNC controllers to provide precise motor control for machine axes.
⚙️ What It Does
- ⚡ Converts incoming AC power into controlled power to drive servo motors
- 🎯 Controls position, speed, and torque of two CNC machine axes
- 🔄 Maintains high‑precision motion using feedback from the servo feedback system (FSSB)
- đź”— Works tightly with FANUC CNC controllers for synchronized axis movement and machining tasks
👉 In simple terms:
It’s the power and control unit that drives two servo motors on a CNC machine.
🧩 Typical Use Cases
- CNC machining centers
- CNC lathes
- Automation systems requiring precise two‑axis motion control
- High‑precision milling and cutting applications
📌 Compatible with FANUC αi servo motors and controlled via FANUC CNC systems.
🔍 How It Compares in the Series
In the A06B‑6127 family, suffixes (like H202, H205, H206) indicate different current/voltage and capacity variants:
- H207 = AiSV‑40/40HV → Balanced dual‑axis with ~40 A class capabilities on each channel
- Other suffixes like H205/H206 refer to different power ratings or one axis heavier load variants (e.g., 20/20, 20/40)
🛠️ Common Symptoms of Failure
When this amplifier has issues, machines may show:
- Servo alarms (SV alarms)
- Axis not moving or unstable motion
- Power trips or drive faults
- Overcurrent or cooling alarm indications
These often require testing or replacement at module level.
âś… Summary
A06B‑6127‑H207 is a dual‑axis servo amplifier (AiSV‑40/40HV) used in FANUC CNC systems to drive two axes with robust power and precision control. It is part of the high‑voltage αi servo drive family and interfaces directly with FANUC controllers for coordinated motion control.
