Description
🔧 FANUC A06B‑6127‑C205 – Description
The part A06B‑6127‑C205 is a unit specification designation for a FANUC servo amplifier module in the Alpha iSV (αi) series, used in CNC machines and industrial motion control systems. It corresponds to the board/wiring variant of a specific amplifier type.
📌 What It Really Means
In FANUC naming conventions:
- A06B‑6127‑H205 is the main order part number for a dual‑axis servo amplifier module (AiSV‑20/20HV).
- A06B‑6127‑C205 is the unit specification / internal designation used in FANUC manuals and wiring diagrams for the same amplifier — i.e., it identifies the specific internal board/wiring configuration tied to H205.
👉 In FANUC technical documentation, the “C” number (C205) reflects the internal unit specification that pairs with the order spec “H205” and the corresponding printed circuit board spec (e.g., A16B‑2203‑0810).
⚙️ What A06B‑6127‑C205 Refers To
- Module Type: Dual‑axis servo amplifier (high‑voltage)
- Corresponding H Part: A06B‑6127‑H205 – Alpha i SV 20/20HV (two axes, balanced power)
- Internal Board: A16B‑2203 series (often 0810 for power/control)
📌 In FANUC manuals and part lists, the C code (like C205) is used alongside H codes (like H205) to specify:
- Unit wiring
- Connector configurations
- Internal board layout
While the H number is used for ordering and replacement, the C number shows up in manuals and parts lists to detail internal specs — but both designate essentially the same amplifier hardware.
đź§© Simple Summary
A06B‑6127‑C205 = the internal unit/wiring specification for the FANUC αi servo amplifier module that is ordered as A06B‑6127‑H205 (AiSV‑20/20HV).
They refer to the same dual‑axis servo drive module, just from different naming perspectives used in documentation vs. parts ordering.
