Fanuc Robotics maintains a globally standardized hardware ecosystem centered around its R-30i series controllers, including the R-30iA, R-30iB, and R-30iB Plus generations. These controllers power various manipulator series, such as the R-2000i, M-series, and LR Mate.
The system is modularly organized into three primary hardware tiers:
- Main Control Logic (CPU/Mainboard)
- Power Transformation Stage (PSU)
- Motion Execution Layer (Alpha i Servo Amplifiers)
This Fanuc Spare Parts Indexprovides a structural classification of these components, enabling a systematic overview of part number prefixes and their functional integration within the Fanuc system environment.
Fanuc System Architecture Mapping
This table defines the structural relationships between Fanuc controller generations and their primary hardware module series to ensure correct compatibility.

Representative Hardware Classifications

| Component Category | Representative Series / Formats | Hardware Functionality |
|---|---|---|
| Mainboards & CPUs | A20B-8201 / A16B-3200 | System Logic & OS Execution |
| Servo Amplifiers | A06B-6117 / A06B-6240 | Motion & Power Conversion |
| iPendant Series | A05B-2255 / A05B-2256 | Human-Machine Interface |
| I/O Modules | A16B-2204 / A20B-2101 | Peripheral Signal Processing |
Frequently Asked Questions
Q1: What is the primary function of this Fanuc Spare Parts Index?
A: This index serves as a high-level structural map of Fanucs controller hardware, categorizing components by their functional role and system generation. It is designed to provide part number prefix consistency for the fanuc circuit board and fanuc power supply collections.
Q2: Are the part numbers listed here equivalent to official Fanuc standards?
A: Yes. All part number formats correspond to official Fanuc hardware nomenclature as used across documentation and system references. This index focuses on established industry formats and series identifiers.
Q3: Does this index cover mechanical arm components like motors?
A: This specific index is focused on controller side hardware. While servo motors are related to the motion layer, they are indexed separately under manipulator-specific hardware guides.
Q4: How are hardware revisions handled in this index?
A: This index maps the base series and generation. Specific version suffixes and hardware revisions are addressed within the detailed product collections to which this index refers.
