🔎 FANUC A06B‑6127‑C255 – What It Is
A06B‑6127‑C255 is not a separate physical part you install or order, but rather a unit specification code used in FANUC’s technical documentation (like parts lists and service manuals). It identifies the internal configuration or wiring specification that corresponds to a particular servo amplifier module in the A06B‑6127 series.
đź“Ś In FANUC naming conventions:
- The “H‑code” (e.g., A06B‑6127‑H255) is the actual servo amplifier module you purchase and install.
- The “C‑code” (e.g., A06B‑6127‑C255) is the internal specification/unit designation used in documentation to describe the same module’s internal wiring/board layout.
🧩 What Module It Corresponds To
The matching H‑part for C255 is:
📌 A06B‑6127‑H255 —
- A 2‑axis FANUC servo amplifier module, part of the Alpha iSV (αi) high‑voltage logic (HVL) series
- Typically described as AiSV‑20/20HVL — meaning it can drive two servo motor axes with balanced power ratings
- Used in CNC systems for precise motion control (X/Y, X/Z, etc.)
đź“Ś Summary
✅ A06B‑6127‑C255 is a unit/specification code in FANUC manuals.
➡️ It refers to the internal specification for the servo amplifier module whose order part number is A06B‑6127‑H255 (AiSV‑20/20HVL).
🔹 H255 = physical amplifier unit you replace or install
🔹 C255 = internal specification used for wiring/assembly documentation
🧠Quick Practical Notes
- When replacing hardware, use the H‑number (e.g., H255).
- If you’re looking at a service manual or parts diagram, the C‑code helps locate the right assembly specifications.
- Inside this amplifier module are internal boards (e.g., A16B‑2203‑0817) that handle power and control — let me know if you want details on those too.
