FANUC A06B-6141-H026#H580 ALPHA i Spindle Amplifier MDL AiSP-26 / Type A2

Overview

The A06B-6141-H026#H580 is a FANUC spindle amplifier from the ALPHA i range, identified as AiSP-26 / Type A2. It is built for CNC-controlled spindle applications where electrical stability, controlled output, and dependable service replacement are essential. In industrial machining, the spindle amplifier is not just another drive cabinet component.

It is one of the key elements that shapes spindle responsiveness, production continuity, and overall machine behavior under real load.

With a rated input of 283-339 V, power rating of 29.8 kW, maximum output of 240 V, and rated output current of 111 A, this model is clearly positioned for serious spindle-drive duty rather than light auxiliary use.

For technical buyers, these figures matter because they indicate where the amplifier sits in the drive hierarchy and what level of spindle demand it is meant to support.

Technical Data

Product Description

The A06B-6141-H026#H580 is designed for spindle-drive applications that require controlled power delivery and stable integration within FANUC CNC systems. In day-to-day plant operation, the quality of a spindle amplifier is measured less by catalog wording and more by how reliably it supports acceleration, load handling, and repeatable machine behavior over time.

This AiSP-26 unit is particularly relevant for maintenance replacement, machine restoration, and inventory planning in facilities that rely on established FANUC platforms.

A correct spindle amplifier helps restore machine readiness efficiently, but just as importantly, it helps avoid the expensive confusion caused by installing a similar-looking but unsuitable model.

Industrial Application Value

For engineering and maintenance teams, the value of this spindle amplifier lies in its practical fit for CNC spindle control. Output capacity, current handling, and model matching all influence whether the machine returns to stable service after installation.

In production environments, any weakness in the spindle-drive chain can show up as lost machining time, abnormal alarms, reduced process confidence, or interrupted throughput.

A well-matched replacement amplifier is therefore part of a broader reliability strategy. Shops that manage downtime well usually verify not only the part number, but also cabinet cooling, power condition, connector integrity, and related spindle hardware before restarting the machine.

Service and Replacement Notes

The original installed label should be checked before ordering. That remains the most reliable way to confirm the correct amplifier.

Buyers should also review the machine’s electrical configuration, because spindle amplifier selection is tied to the original drive architecture.

Where the failed unit shows signs of heat stress or the cabinet environment is poor, corrective maintenance should be performed alongside replacement.

In industrial electronics, long service life depends on the system around the module, not only the module itself.

FAQ

Q1: What kind of application is the A06B-6141-H026#H580 intended for?
This model is intended for CNC spindle-drive applications within the FANUC ALPHA i platform. Its rated electrical values and spindle-amplifier classification show that it is designed for substantial drive duty rather than minor auxiliary functions.

In practice, it belongs in machine environments where stable spindle control and dependable electrical performance are required for continuous industrial operation.

Q2: What do the 29.8 kW and 111 A ratings tell a technical buyer?
These figures help define the working class of the amplifier. The 29.8 kW power rating indicates a significant spindle-drive capability, while the 111 A rated output current points to the amplifier’s ability to support demanding spindle-side load conditions.

For technical procurement and maintenance planning, those values are useful because they help distinguish this model from lower-capacity spindle units that may appear similar at first glance.

Q3: Why is model matching especially important for spindle amplifiers?
Because spindle amplifiers are tightly linked to the machine’s drive architecture. A mismatch can lead to installation issues, startup faults, unstable spindle behavior, or extended troubleshooting during commissioning.

In industrial service work, exact model and suffix verification is a basic control step that helps protect both the replacement process and the machine’s return-to-production timeline.

Q4: What should be inspected before replacing this spindle amplifier?
The technician should confirm the exact part number, inspect cabinet cooling performance, check connector and terminal condition, review any fault history, and verify that the surrounding spindle-drive system has no secondary issues.

It is also worth checking whether the original failure may have been influenced by contamination, heat buildup, or electrical stress. Replacing the amplifier alone without checking the operating environment may not fully solve the problem.

Q5: Is this amplifier suitable for maintenance stock and planned spare strategies?
Yes. For operations running FANUC CNC equipment, a correctly identified spindle amplifier like the AiSP-26 can be a valuable maintenance stock item, especially where machine uptime has direct production impact.

Holding the right spare helps shorten recovery time when failures occur, and it gives maintenance teams a more controlled response than emergency sourcing after the machine has already stopped.
