A06B-6096-H101#H Fanuc Servo Amplifier Module A06B6096H101#H A06B-6096-H101#H

Fanuc A06B-6096-H101#H | Alpha Servo Amplifier Module — SVM1-12, Single-Axis, FSSB Fiber Optic, 283–325V / 0.75kW, 3.0A / 230V Output

Overview

The Fanuc A06B-6096-H101#H is the SVM1-12 variant within Fanuc's A06B-6096 FSSB alpha servo amplifier module series — the entry-level single-axis module in this family, rated at 3.0A continuous output from a 0.75kW DC bus input.

The full part number A06B-6096-H101#H is how Fanuc identifies this specific hardware variant of the H101 module, where the #H suffix designates a particular control card PCB revision and option configuration that distinguishes it from the base H101 in certain machine-specific installations.

When sourcing a replacement, the complete part number including the #H suffix must be matched, as different suffix variants may carry different PCB configurations or software SRAM states that are specific to the machine's original build.

As the SVM1-12, this module occupies the smallest current class in the A06B-6096 FSSB SVM family.

While larger alpha SVM modules handle the main machining axes — the X/Y/Z axes that bear the cutting forces and inertia loads of production work — the SVM1-12 is selected for auxiliary axis functions where the motor is small, the load is light, and positioning accuracy rather than sustained high torque is the primary requirement.

Small rotary tables, C-axis orientation drives on turning centres, tool magazine indexing axes, and ancillary positioning stages are all natural applications for the SVM1-12's 3.0A output range.

The FSSB (Fanuc Serial Servo Bus) fiber optic interface connects this module into the i-series CNC's servo communication ring, alongside any other FSSB-equipped SVM modules in the same drive stack.

This ring-based architecture is the key advantage of the A06B-6096 series over the older A06B-6079 PWM series: one fiber optic cable chain replaces the individual PWM cables that connected each axis independently to the CNC, reducing cabinet wiring complexity and providing noise immunity through the optical medium.

Key Specifications

The #H Suffix — What It Means for Ordering and Replacement

In Fanuc's servo module part numbering system, the suffix after the hash sign (#) identifies a specific hardware or software configuration within the base module. For the A06B-6096-H101#H, this suffix denotes a particular PCB revision state — the specific combination of wiring board revision, control card version, and any SRAM-resident firmware — that was specified for a given machine build or production period.

When replacing a failed A06B-6096-H101#H in a machine, the correct approach is to match the full part number including the #H suffix.

The base module (without the suffix, or with a different suffix) carries the same electrical ratings and performs the same servo control functions, but may carry a different control card revision or SRAM configuration.

In most replacement scenarios this difference is minor and transparent to the machine's operation, but for machines with specific software-dependent servo functions or for installations where the original supplier specifies the exact suffix, #H should be specified when ordering.

Some service providers require a refundable SRAM deposit when the software update specific to this suffix revision needs to be loaded into the replacement module.

SVM1-12 Motor Compatibility — α1 and α2 Class

The α1/3000 motor produces 1N·m of continuous torque at its 3000rpm rated speed, drawing rated current comfortably within the SVM1-12's 3.0A continuous rating.

The α2/2000 steps to 2N·m continuous at 2000rpm — still well within the 3.0A envelope. 

These are the two standard motor companions for the SVM1-12 in Fanuc's alpha system motor selection guide, chosen for applications where rapid positioning response matters more than sustained high force.

At only 0.75kW input from the DC bus, the SVM1-12 contributes negligibly to the total PSM demand calculation in any multi-module drive stack.

A machine adding an SVM1-12 to an existing installation of larger SVM modules barely changes the PSM loading — the 0.75kW input is the minimum contribution of any alpha SVM module in the series.

FSSB Ring Position and CNC Integration

The A06B-6096-H101#H connects into the FSSB ring via its COP10A input (fiber optic from the preceding module or CNC) and COP10B output (to the next module or back to the CNC). The CNC's FSSB initialisation screen assigns the axis number to this module based on its physical position in the ring — this axis number ties the drive to the CNC's parameter set for that axis.

When replacing the module, the ring position must be maintained so the axis number assignment and parameters remain consistent.

The 60mm narrow profile allows the SVM1-12 to fit alongside larger-width SVM modules on the same alpha drive rail without wasting cabinet space.

In a three-axis machine where one axis is the SVM1-12 and the other two are 60mm or wider SVM modules, the H101#H occupies the minimum possible rail allocation for its axis function.

FAQ

Q1: What specifically does the #H suffix identify, and does it affect the module's performance?

The #H designates a specific hardware revision configuration of the A06B-6096-H101 — primarily the control card PCB revision and its associated SRAM content. The electrical performance, current ratings, and servo control functions are identical to the base H101.

The #H may enable or configure specific servo software features relevant to the machine's CNC version.

For most standard replacement purposes the #H variant is functionally interchangeable with other suffix variants of the H101; however, when the machine documentation specifies A06B-6096-H101#H, ordering the exact suffix is the safest approach, particularly if the machine's servo tuning is closely coupled to the specific SRAM revision.

Q2: Can A06B-6096-H101#H replace the older A06B-6079-H101 (PWM Type A/B) module?

No — these two modules share the SVM1-12 designation and identical electrical ratings (3.0A, 0.75kW, 283–325V) but use entirely different CNC interfaces.

The A06B-6096-H101#H communicates via FSSB fiber optic for i-series controls; the A06B-6079-H101 uses PWM Type A or B for Series 15/16/18/21 non-i controls. 

The physical FSSB connector on the #H module has no equivalent on the A06B-6079 version. A machine with a PWM CNC axis interface cannot use the FSSB module, and vice versa.

Q3: What alpha servo motors are specifically matched to the A06B-6096-H101#H?

The standard motor pairings for the SVM1-12 at 3.0A are the α1/3000 (1N·m, 3000rpm) and α2/2000 (2N·m, 2000rpm).

These small-frame alpha motors are used on light positioning axes — C-axis on small turning centres, rotary tool head orientation, small pallet or workpiece indexing systems, and similar low-torque positioning duties.

Motors in the α3 class and above draw more than 3.0A continuous at full rated torque and require the SVM1-20 (A06B-6096-H102, 5.9A) or larger.

Q4: What FSSB alarms specifically appear on this module?

Alarm L (FSSB disconnect at COP10A) indicates loss of the fiber optic input signal — inspect the COP10A connector and incoming cable for contamination or damage. Alarm U (FSSB disconnect at COP10B) indicates a problem with the output ring segment — inspect COP10B and the cable to the next module.

For servo output faults, Alarm 8 indicates L-axis overcurrent or IPM alarm — disconnect motor cables and verify motor insulation resistance (acceptable: several hundred megaohms to earth) before condemning the module.

All FSSB alarm handling follows the standard i-series FSSB servo alarm diagnostic procedure applicable to the machine's CNC generation.

Q5: Is a software (SRAM) update required when fitting a replacement A06B-6096-H101#H?

It may be. The SRAM content of the control card stores servo software parameters specific to the module's configuration. When a replacement module carries a different SRAM revision than the original, Fanuc's commissioning procedure requires loading the correct SRAM content for the specific suffix variant.

Some service providers hold this SRAM content in their inventory and include the update as part of the reconditioning process; others require a refundable deposit to cover the SRAM loading service. Before fitting a replacement, confirm with the service provider that the #H SRAM version is correctly loaded and verified on the replacement module before installation.
