Description
A06B‑6127‑C207 isn’t itself a standalone physical part you would buy or install — it is the unit specification code for a specific FANUC servo amplifier module in the A06B‑6127 series.
📌 In FANUC part numbering:
- The “H” code (e.g., A06B‑6127‑H207) is the actual amplifier module you order and install.
- The “C” code (e.g., C207) is used in FANUC manuals and internal documentation to specify the internal unit/wiring/circuit configuration that corresponds to that H‑part. It doesn’t refer to a separate board you’d buy; it identifies the same amplifier’s specification for service manuals, parts lists, and wiring diagrams.
👉 So:
A06B‑6127‑C207 = the internal unit/wiring specification for the servo amplifier ordered as A06B‑6127‑H207.
🔧 What the Corresponding Amplifier Is
The matching H‑part — A06B‑6127‑H207 — is a FANUC αiSV dual‑axis servo amplifier module typically described as:
- Model: ALPHA i SERVO MODULE MDL AiSV‑40/40HV (dual‑axis high‑voltage amplifier)
- Function: Drives two servo motor axes, controlling position, speed and torque in CNC motion systems.
- Common in machining centers, lathes and other FANUC‑controlled automation.
📌 In FANUC documentation, the “C” specification like C207 links to wiring diagrams and internal assemblies for that exact amplifier. It is useful for technicians referencing manuals, but for parts ordering and replacement, the H207 designation is what matters.
✅ Summary:
A06B‑6127‑C207 = internal wiring/unit specification for the FANUC servo amplifier module A06B‑6127‑H207 (AiSV‑40/40HV) used to drive two servo motor axes in CNC applications.
