| Place of Origin | JAPAN |
| Brand Name | FANUC |
| Certification | CE ROHS |
| Model Number | A06B-6114-H207 |
The A06B-6114-H207 is a 2-axis FANUC Alpha i servo amplifier module identified in the αi amplifier lineup as αi SV 40/40, corresponding to the SVM2-40/40i class.
It belongs to the 200-V input series and is used with i-Series CNCs (Model B) through the FSSB interface, which places it squarely in the mainstream αi modular servo architecture for machine-tool control.
This model is typically chosen when a machine requires a true two-axis amplifier in a balanced 40/40 current class rather than a mixed-axis combination. In practical service work, that matters because the H207 is not just a similar-looking drive module; it is a defined dual-axis amplifier with equal current capacity on both the L and M channels.
That makes it especially useful where the original machine design depends on keeping a matched two-axis servo structure without changing the cabinet layout or the axis-side electrical balance.
FANUC’s αi descriptions also place this amplifier in the 60-mm-wide, external-fin module group, with Outline Drawing 2, Panel Cut-out 2, and Maintenance Area 1.
For buyers and maintenance teams, that is valuable because correct electrical matching is only part of the job; the replacement also needs to fit the original enclosure and cooling arrangement cleanly.

Q1: What exactly is the A06B-6114-H207 in the FANUC range?
It is a 2-axis Alpha i servo amplifier module that FANUC identifies as αi SV 40/40 in the start-up manual and SVM2-40/40i in the descriptions manual.
That means the unit is designed to drive two servo axes from one amplifier body, not one axis and not three. For replacement work, that distinction matters because axis count is one of the core compatibility checks.
Q2: What is the current class of this amplifier?
FANUC’s SVM specification table shows the L-axis at 13 Arms with a 40 Apeak nominal current limit and the M-axis at 13 Arms with a 40 Apeak nominal current limit. In industrial terms, that places the H207 squarely in the 40/40 two-axis class.
It is useful information for a technical buyer because it separates this model from the nearby 20/40, 40/80, and 80/80 variants that can look similar in a cabinet but are not the same electrically.
Q3: What CNC interface does this module use?
The FANUC descriptions manual states that the common specification for this SVM group applies to i-Series CNCs (Model B) with the FSSB interface. That interface detail is important.
In service work, a correct amplifier is not defined only by its current class; it also has to match the CNC communication architecture the machine was originally built around.
Q4: What should be checked before ordering or installing an H207?
A technician should confirm the exact part number on the installed unit, verify that the machine uses the correct αi/FSSB architecture, and make sure the cabinet layout matches the 60 mm-wide, external-fin frame style associated with this model class.
It is also good practice to review cooling conditions, panel cut-out suitability, and cable condition before startup. On modular FANUC amplifiers, the most expensive mistakes usually come from assuming that a similar-looking unit is close enough.
Q5: Why is this model valuable in legacy CNC maintenance?
Because it lets a machine keep its original dual-axis amplifier structure without forcing a cabinet redesign or a control-side workaround. When a machine was built around a two-axis 40/40 αi amplifier, the cleanest path back to production is usually a correct model-for-model replacement.
That reduces commissioning uncertainty, protects the original drive topology, and shortens troubleshooting time after installation.
