FANUC A06B-6117-H208 Dual-Axis Alpha i Servo Module

Overview

The A06B-6117-H208 is a dual-axis Alpha i servo amplifier module designed for CNC motion systems that require reliable two-axis control within the Alpha i drive platform. Public replacement-channel references consistently identify this model as AiSV-40/80, and they place it in the A06B-6117 family of AC servo drives.

That makes it most appropriate for installed-machine support, repair planning, and exact replacement work rather than for generic motion-control selection.

In practical machine service, a module like this is chosen when the original dual-axis servo structure needs to be preserved without changing the surrounding control architecture. Because it is a mixed-capacity dual-axis unit, it is especially relevant where one axis and the second axis do not share the same current class, but still need to remain inside one integrated Alpha i amplifier.

That is one reason technical buyers usually search by exact model designation rather than by broad product category alone.

Public references also show that this amplifier is associated with 283–339 V rated input, 240 V maximum output voltage, and rated output current of 13 A on the L axis and 19 A on the M axis.

Those values give the module a clear technical identity inside the Alpha i family and help distinguish it from smaller or symmetrical dual-axis models.

Key Specifications

Dual-Axis Mixed-Capacity Design

One of the most useful practical points about A06B-6117-H208 is that it is not just a two-axis amplifier, but a mixed-capacity two-axis amplifier.

The AiSV-40/80 designation and the published 13 A / 19 A split show that the two controlled axes do not belong to the same current class. 

In real machine architecture, that matters because the original cabinet and motor pairing are often built around this exact asymmetrical arrangement.

That detail makes the product description more useful to technical buyers.

Instead of calling it simply a “servo drive,” identifying it as AiSV-40/80 helps maintenance teams and procurement staff confirm that the replacement belongs to the correct Alpha i dual-axis family.

FAQ

Q1: What kind of product is A06B-6117-H208?
It is a FANUC Alpha i dual-axis servo amplifier module identified as AiSV-40/80. In practical CNC use, it serves as a dedicated two-axis servo drive inside installed FANUC motion systems rather than as a general-purpose stand-alone amplifier.

Q2: Why is the AiSV-40/80 designation important?
It tells the buyer that the module belongs to a specific Alpha i dual-axis class with mixed axis capacity. In real replacement work, that is important because the original machine may depend on that exact axis-current structure rather than on a symmetrical two-axis amplifier.

Q3: Are the 13 A and 19 A axis ratings useful in application matching?
Yes. They help confirm that the module is intended for a mixed-capacity dual-axis role.

For service engineers, that makes the model easier to distinguish from other Alpha i amplifiers that may look similar but belong to a different output class.

Q4: Is this module mainly for new machine design or replacement support?
It is far more naturally suited to replacement, repair, and installed-machine support.

Public references present it through service and spare-parts channels, which is typical for FANUC drive modules used to keep existing production equipment running.

Q5: What should buyers verify before ordering?
Buyers should confirm the exact part number, the AiSV-40/80 designation, the dual-axis architecture, the input/output class, and the installed control environment.

For FANUC amplifier modules, correct family and axis matching are usually more important than broad category similarity.
