A06B-6096-H101#H Fanuc Servo Amplifier Module A06B6096H101#H A06B-6096-H101#H
FANUC A06B-6096-H101#H | Alpha SVM1-12 Single-Axis FSSB Servo Module -- 3.0A / 0.75 kW / 283-325V / α1 / α2
Entry-Level FSSB Module for Light Auxiliary Axes
The A06B-6096-H101#H is the SVM1-12 — the smallest-current single-axis module in FANUC's A06B-6096 FSSB alpha servo series. At 3.0A continuous and 0.75 kW, it is not sized for the main cutting axes that carry production loads. Its application is the category of auxiliary servo axes that need accurate positioning in a compact form rather than sustained torque: C-axis orientation on turning centres, small rotary table drives, tool magazine indexing axes, and secondary positioning stages.
The α1/3000 and α2/2000 motors are the standard motor companions — 1 Nm and 2 Nm continuous torque respectively, both well within the 3.0A envelope. For motor classes above α2, the SVM1-12 does not have the current capacity and a higher-rated module is required.
The 0.75 kW DC bus draw is negligible in the PSM sizing calculation for a multi-module cabinet — adding an SVM1-12 to an existing drive stack changes the total PSM demand by less than any other alpha SVM module in the series.

#H Suffix — Match the Complete Part Number
The #H suffix identifies a specific PCB revision and SRAM configuration of the base H101. Electrically and functionally the performance is identical across H101 suffix variants. However, the SRAM content on the control card stores servo software parameters specific to the suffix revision — replacing with a different suffix can require SRAM reloading to restore the original servo function configuration.
When ordering a replacement for a machine specified as A06B-6096-H101#H, match the complete part number including #H. Some service providers include SRAM verification as part of their reconditioning process; confirm this before installation.
FSSB Ring Connection
The module connects into the FSSB ring at COP10A (input from preceding module or CNC) and COP10B (output to next module). The CNC's FSSB initialisation screen assigns the axis number based on ring position. When replacing the module, maintain the ring position so the axis number assignment and parameters remain consistent.
FAQ
Q1: Can the A06B-6096-H101#H replace the older A06B-6079-H101 (PWM interface)?
No. Both carry the SVM1-12 designation and identical electrical ratings, but they 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. These interfaces are not compatible — a machine with a PWM CNC axis interface cannot use the FSSB module and vice versa.
Q2: What alpha servo motors are matched to the A06B-6096-H101#H?
The α1/3000 (1 Nm, 3000 rpm) and α2/2000 (2 Nm, 2000 rpm). These small-frame alpha motors are used on light positioning axes — C-axis on small turning centres, rotary table positioning, small pallet indexing. Motors in the α3 class and above draw more than 3.0A at full rated torque and require the SVM1-20 (H102, 5.9A) or larger.
Q3: Does fitting a replacement require SRAM update?
It may. The SRAM content stores servo software parameters specific to the #H revision. When a replacement carries a different SRAM version, FANUC's commissioning procedure requires loading the correct content for this suffix. Confirm with the service provider that #H SRAM is correctly loaded and verified on the replacement before installation.
Q4: What FSSB alarms appear on this module?
Alarm L at COP10A indicates loss of the fiber optic input signal — inspect the COP10A connector and incoming cable for contamination or damage. Alarm U at COP10B indicates a problem with the output ring segment. For servo output faults, Alarm 8 indicates L-axis overcurrent or IPM alarm — disconnect motor cables and verify motor insulation resistance before condemning the module.
Q5: The SVM1-12 drives a C-axis on a turning centre. What is the typical cause of sudden FSSB alarm on this axis?
On C-axis drives in turning centres, the fiber optic cables from the main drive cabinet to the C-axis amplifier are often routed across moving machine sections. Cable fatigue at bend points from continuous machine cycling is the most common cause of sudden FSSB alarms on remote auxiliary axes. Inspect the cable routing for damage near the C-axis amplifier mounting position and at any cable management clips before replacing the module.
