FANUC A06B-6096-H201 | Alpha SVM2-12/12 Dual-Axis Servo Module — 3A / 3A / 283–325V / FSSB

SVM2-12/12 — Compact Dual Axis at the Low-Current End

The A06B-6096-H201 is the SVM2-12/12 — the lowest-current dual-axis module in FANUC's Alpha FSSB SVM family, with 3.0 Arms on both L and M channels. It handles two servo axes from a single module at the small end of the Alpha SVM2 range, making it the correct unit for compact CNC machine configurations where two light-duty axes share an amplifier without requiring the current capacity of the 40/40 or 80/80 variants that fill the same cabinet slot at higher cost.

Like all modules in the A06B-6096 series, the H201 draws from the shared DC bus supplied by a companion Alpha PSM (Power Supply Module) and communicates with the CNC over FSSB fibre-optic cable. FSSB axis assignment is defined in the CNC's axis parameters — each L and M channel gets its own FSSB address in the drive chain.

The SVM2-12/12 designation distinguishes this module from higher-current dual-axis variants in the same family. The per-channel current rating is the primary selection criterion: the motor's continuous stall current must fall within the amplifier channel's 3.0 Arms rating. Exceeding this leads to overcurrent faults or thermal overload. If the installed machine uses motors that require more than 3.0 Arms per axis, the SVM2 variant with a higher current class is the correct specification.

Key Specifications

SVM2 Family Context

The SVM2 designation covers all dual-axis modules in the A06B-6096 series. The H201 at 3.0 A/3.0 A is the smallest. Adjacent variants include higher per-channel current ratings for motors with greater stall current demands. The physical form and FSSB communication architecture are shared across the SVM2 family — but modules with different current ratings have different internal power components, different rated thermal performance, and different motor parameter configurations. They are not interchangeable.

When replacing an H201, confirm the full part number from the installed module's label. An adjacent SVM2 number in the cabinet may have a higher current rating and a different motor type mapping — fitting it against an H201's motor load risks parameter mismatch or amplifier undersizing in the other direction.

FAQ

Q1: What is the A06B-6096-H201 in FANUC's SVM2 range?

It is the SVM2-12/12 — the lowest-current dual-axis module in the Alpha FSSB SVM series. Both L and M channels are rated at 3.0 Arms continuous. It drives two servo axes from one module at the small end of the Alpha SVM2 current range, for compact CNC machine configurations with light-duty axis motors.

Q2: Does the A06B-6096-H201 require a separate PSM power supply?

Yes. The A06B-6096 SVM series draws from a shared DC bus supplied by an Alpha PSM (A06B-6087 or A06B-6088 series). The PSM must be rated to supply the combined current demand of all connected SVM and SPM modules. The H201 does not self-rectify its own AC input.

Q3: Can a higher-current SVM2 variant substitute for the H201?

Physically it may fit the same cabinet slot, but it is not a straightforward substitution. Higher-current variants have different motor parameter configurations and different thermal ratings. The CNC's axis parameters must be set for the motor type actually connected — fitting a higher-current module against a low-current motor without correct parameter configuration produces motor type mismatch alarms or incorrect velocity scaling.

Q4: Both L and M axes alarmed simultaneously. Is this an H201 module fault?

Simultaneous alarms on both axes of an SVM2 module can indicate a module-level fault (shared DC bus loss or control power supply failure inside the module) or an upstream PSM fault. Check the PSM status and verify the FSSB cable connections first — a PSM fault takes all SVM modules on the bus offline simultaneously. Single-axis alarms are more likely to be motor or encoder faults.

Q5: Where is the A06B-6096-H201 sourced?

Through the FANUC Alpha FSSB module aftermarket — CNC repair specialists and Alpha amplifier dealers hold exchange and surplus stock. Confirm the H201 (SVM2-12/12) specifically — the physical form of SVM2 variants can appear similar in a cabinet while the electrical specification differs. Request a functional test on both L and M channels before accepting any exchange unit.
