Product Description & Procurement Guide
Detailed Technical Specification
Models of the Same Series
The FANUC A06B-6089-H104 is a single-axis Alpha Series Servo Amplifier Unit (SVU 1-40) widely used in CNC machining centers and robotic manufacturing lines. Unlike modular amplifiers that require a separate power supply, this unit is critical for controlling specific axis feeds in legacy FANUC systems (such as the 16/18/21-Model B controls). Finding a reliable replacement for A06B-6089-H104 is urgent when your machine stops due to drive alarms. We specialize in sourcing and supplying Genuine FANUC parts in New condition to get your production line back up and running.
• Motion Control Logic: Converts digital PWM signals from the CNC controller into precise current for the servo motor.
• System Integration: specifically designed to drive Fanuc Alpha Series Servo Motors (e.g., Model a6/3000 or a12/3000).
• Feedback Processing: Processes high-speed encoder feedback to ensure accurate positioning and speed control during complex machining cycles.
• Drive Protection: Features internal diagnostics to detect over-current (Alarm 8/9/A) or IPM thermal faults, protecting the motor and machine mechanics.
We understand that FANUC part numbers can be confusing. We have compiled a comparison of similar models in our existing A06B series inventory, which may provide suggestions for users' purchasing decisions.

Key Funtion & “When to Buy” |
|
A06B-6089-H104 |
Servo Unit (SVU 1-40) |
Role: Single-axis drive (The Target Item). When to Buy: Buy this if your specific axis (X, Y, or Z) shows an alarm (e.g., "AL. 12") on the drive display |
|
A06B-6079-H106 |
Servo Module (SVM 1-80) |
Role: Standard Alpha Amp. When to Buy: This requires an external Power Supply (PSM). Buy this if you have a modular Alpha rack and one axis is dead |
|
A06B-6079-H208 |
Dual-Axis Module (SVM 2-40/40) |
Role: 2-Axis Controller. When to Buy: Controls two motors from one box. If you lose two axes simultaneously, this module is likely the fault |
|
A06B-6077-H106 |
Power Supply (PSM-5.5) |
Role: The Power Source. When to Buy: Feeds power to 6079/6089 amps. Critical: If no LED lights are on for any drive, replace this PSM first |
|
A06B-6114-H106 |
Alpha i Servo (SVM1-80i) |
Role: Newer Generation (Ai Series). When to Buy: For newer machines with yellow labels. NOT compatible with 6089/6079 older series |
|
A06B-6120-H075 |
Alpha i Power (PSM-30i) |
Role: Newer Gen Power Supply. When to Buy: Power supply for the 6114 series. Connectors are different from the 6077 unit |
|
A06B-0116-B203 |
AC Servo Motor (Model Alpha) |
Role: The Motor Hardware. When to Buy: If the drive is good but the motor is vibrating or overheating, you need the motor, not the amplifier |
Trade Expert Note: Do not mix "Alpha" (6079/6089) and "Alpha i" (6114/6120) series modules unless confirmed by your system integrator. They use different optical fiber protocols.
• CNC Milling Centers: The A06B-6089-H104 is a workhorse for vertical machining centers (VMC), controlling the table movement (X/Y axis) for precision cutting.
• Automotive Production: Used in high-speed transfer lines for drilling and tapping engine blocks.
• Injection Molding: often found driving the ejector or clamp mechanisms in all-electric molding machines.
Q: My display shows Alarm "8" or "9". Is the H104 faulty?
A: These are high-current alarms. It often indicates a short circuit in the drive's transistor module. We recommend swapping the unit with a known good A06B-6089-H104 to confirm. We sell tested surplus units ready to install.
Q: Do you offer repair services or technical diagrams?
A: We are a global parts supplier, not a repair shop. We do not provide schematic diagrams or onsite repair. However, we ensure our parts are pulled from working environments or bench-tested before shipping to assist your maintenance team.
Q: What is the difference between "Refurbished" and "New"?
A: "Refurbished" means the unit was used, cleaned, and tested. "New Surplus" means it is old stock that was never installed, often in the original FANUC box. Ask our sales team for the price of new A06B-6089-H104.
• Live Video Verification: We provide Real-Time Video Inspection. We can show you the pins of the A06B-6089-H104 to ensure no bent pins or stripped screws exist on the connector.
• Global Logistics: We offer International shipping for ATE components with ESD-safe packaging.
• Stock Status: Contact us for the latest A06B-6089-H104 stock availability and pricing.
