FANUC A06B-6096-H104 Alpha Servo Amplifier Module SVM1-40L

Overview

The FANUC A06B-6096-H104 is an Alpha-series servo amplifier module officially listed as SVM1-40L with an FSSB interface. In FANUC’s ordering information for the 200-V input series, this model is shown as a standard 1-axis amplifier with external dimensions of 380 × 60 × 307 mm.

That tells you two things immediately. First, it is a single-axis module, which makes it suitable for machine designs where one amplifier is dedicated to one servo channel.

Second, it sits in the larger 40L frame within the SVM1 family, so it is not the smallest unit in the range and should be chosen for actual model match, not by appearance alone.

Key parameters

Technical Profile

In FANUC’s individual specification table, SVM1-40L is associated with applicable motor examples including α3/3000, α6/2000, α12/2000, α22/1500, and αC22/1500.

The same table gives a rated output current of 12.5 Arms and a nominal current limit of 40 Ap for this model class. FANUC also lists the common SVM control method as sine-wave PWM control with transistor (IGBT) bridge.

From a product-page perspective, that makes the H104 easier to position honestly. It is not just “a servo amplifier”; it is a defined single-axis Alpha module in the 40L class, built for CNC servo applications where predictable current capability and correct system pairing matter. Buyers looking at this part are usually solving a real machine-side requirement, not browsing an abstract catalog.

Application and Service Value

The A06B-6096-H104 works best as an exact replacement in a FANUC servo system already designed around the FSSB architecture.

When a machine has been built around that communication structure, the practical goal is not to substitute “something close.” The goal is to fit the correct amplifier class, preserve the original control design, and return the axis to stable operation without unnecessary rewiring or parameter confusion.

For technical procurement, the value of this model is clarity. The FANUC manual identifies the frame, the interface type, the output-current class, and examples of applicable motors. That gives engineers enough grounded information to verify whether the installed amplifier and the replacement target actually belong to the same electrical family.

FAQ

Q1: What is the official model designation of A06B-6096-H104?
FANUC lists A06B-6096-H104 as SVM1-40L, which means it is a single-axis servo amplifier module in the Alpha series using the FSSB interface. That designation is the key reference point for matching the part during service or replacement.

Q2: What output class does this amplifier belong to?
According to FANUC’s individual specification table, SVM1-40L is assigned a rated output current of 12.5 Arms and a nominal current limit of 40 Ap.

In industrial terms, that places it in the 40-class single-axis amplifier group rather than the smaller 20-class units.

Q3: What motors are officially shown with SVM1-40L in the manual?
The FANUC manual lists example applicable motors including α3/3000, α6/2000, α12/2000, α22/1500, and αC22/1500.

That does not mean every application decision should be made from a short list alone, but it does show the intended motor class and gives buyers a solid starting point for compatibility review.

Q4: Why is the FSSB interface important when buying this model?
Because FANUC separates amplifier ordering numbers by interface family in the official ordering section.

A06B-6096-H104 is specifically the FSSB-interface version, so using the exact interface-matched part helps avoid installation issues and preserves the communication method the CNC was designed to use.

Q5: What should a maintenance team verify before installing a replacement H104?
They should confirm the installed ordering number, the CNC interface type, the intended motor pairing, and the physical fit in the cabinet.

FANUC also cautions users to ensure the motor/amplifier combination is appropriate and that valid parameters are set, because incorrect combinations can stop the system from operating normally and can damage the amplifier.
