Description
🔧 FANUC A06B-6124-H105 – Alpha i Servo Amplifier Module (Single-Axis / Very High Power / Special Application)
FANUC A06B-6124-H105 Servo Amplifier
🧠 Model Description
A06B-6124-H105 is a FANUC Alpha i (αi) single-axis servo amplifier from the 6124 series, designed for very high-power applications or specialized axes. It is the highest power single-axis module in the 6124 series, used for heavy-duty or special servo motors.
⚙️ Key Technical Details
- Type: AC Servo Amplifier
- Series: Alpha i (αi) – 6124 series
- Variant: H-type (standard full-size module)
- Axes: 1-axis
- Current Rating: Very High (~30–50A typical, depending on configuration)
- Communication: FSSB (Fiber optic servo bus) compatible
⚙️ What “H105” Means
- H = Standard amplifier (full-size)
- 1 = Single-axis module
- 05 = Very high-power rating (top of 6124 series)
👉 Simple explanation: H105 = single-axis, very high-power module
⚙️ What It Does
- Drives one high-power servo motor
- Controls:
- Position
- Speed
- Torque
- Interfaces with CNC via FSSB
- Supports heavy-duty axes such as:
- Large rotary tables
- Main feed axes
- High-inertia loads
🏭 Applications
- CNC machines with high-torque single axes
- Industrial automation where extreme force or high inertia control is needed
- Situations where H102-H104 would be insufficient
🔍 Key Features
- ✔ Single-axis, very high-power module
- ✔ Standard H-type design (full footprint)
- ✔ Compatible with αi servo motors
- ✔ Handles extremely high current
- ✔ Supports FSSB communication
🧠 Simple Explanation
👉 A06B-6124-H105 is the top-power single-axis FANUC servo amplifier, designed for extremely heavy-duty or high-inertia applications that require the most current and torque in the 6124 series.
