📦 FANUC A06B-6127-C155 — Description
Part Number: A06B-6127-C155
Description: ALPHA i SERVO MODULE MDL AiSV-80HVL — a single-axis high-voltage servo amplifier (servo drive) used in CNC machines and industrial automation systems.
🔧 What It Is
The A06B-6127-C155 is part of FANUC’s A06B-6127 Alpha i (αiSV) series of servo amplifier modules.
It is the C-variant of A06B-6127-H155, which is officially described as:
👉 “ALPHA i SERVO MODULE MDL AiSV-80HVL”
✔ This means:
- C155 = same base model as H155 (AiSV-80HVL)
- Difference is typically internal configuration / revision / unit version, not functional performance
⚙️ Function & Operation
- Receives motion commands from a FANUC CNC controller
- Converts them into controlled electrical power
- Drives a single servo motor axis with high precision for:
- Position
- Speed
- Torque
This ensures accurate and reliable motion control in industrial machinery.
📊 Technical Context (AiSV-80HVL Class)
- Model Class: AiSV-80HVL (high-voltage compact/medium-power class)
- Series: A06B-6127 Alpha i
- Voltage: ~400 V AC (three-phase industrial supply typical)
- Axis Control: Single-axis
- Communication: FANUC FSSB (fiber optic servo bus)
- Performance: Designed for precise torque and speed control in demanding environments
🏭 Applications
Commonly used in:
- CNC machining centers (milling, turning, grinding)
- Industrial robots
- Automated production lines
- Precision motion control systems
Installed inside the machine electrical cabinet as part of the servo drive system.
📌 Simple Summary
👉 A06B-6127-C155 = FANUC Alpha i servo amplifier (AiSV-80HVL, single-axis)
👉 Medium-power, high-voltage servo drive for precise motion control
👉 Equivalent to A06B-6127-H155, with a different suffix (configuration/revision)
