🔧 FANUC A06B-6127-H103 – Alpha i Servo Amplifier Module (Dual-Axis / Medium Power)
FANUC A06B-6127-H103 Servo Amplifier
🧠 Model Description
A06B-6127-H103 is a FANUC Alpha i (αi) dual-axis servo amplifier module from the 6127 series, designed for medium-power applications. It is used to drive two axes simultaneously that require more current and torque than the low-power H102 module.
⚙️ Key Technical Details
- Type: AC Servo Amplifier
- Series: Alpha i (αi) – 6127 series
- Variant: H-type (standard full-size module)
- Axes: 2-axis (dual-axis)
- Current Rating: Medium (~10–15A typical, depending on configuration)
- Communication: FSSB (Fiber optic servo bus) compatible
⚙️ What “H103” Means
- H = Standard full-size module
- 1 = Dual-axis module
- 03 = Medium-power variant within the 6127 series
👉 Simple explanation: H103 = dual-axis, medium-power standard module
⚙️ What It Does
- Drives two medium-power servo motors simultaneously
- Controls:
- Position
- Speed
- Torque
- Interfaces with CNC via FSSB
- Ideal for:
- Medium-load axes on CNC machines
- Auxiliary dual-axis systems requiring more torque than H102
🏭 Applications
- Dual-axis feed axes on CNC machines
- Rotary tables or light-to-medium dual-axis automation axes
- Industrial applications where medium power is required for two axes
🔍 Key Features
- ✔ Dual-axis, medium-power module
- ✔ Standard H-type design (full footprint)
- ✔ Compatible with αi servo motors
- ✔ Supports FSSB communication
- ✔ Handles moderate current loads for dual axes
🧠 Simple Explanation
👉 A06B-6127-H103 is a medium-power, dual-axis FANUC servo amplifier module, designed to control two axes simultaneously in moderate-load CNC or automation applications.
