- R-J3 / R-J3iB: Legacy systems that require specialized, hard-to-find components.
These controllers integrate multiple electronic modules including:
- CPU boards
- Servo amplifiers
- Power supply modules
- Communication boards
These components work together to ensure precise robot movement and stable automation control.
2: High-Demand FANUC Spare Parts
The following components are among the most frequently replaced FANUC spare parts.
Teach Pendants(HMI)
Essential for programming and diagnostics. We offer new and refurbished units, including:
- iPendant Series: A05B-2255, A05B-2522, and A05B-2301 models.
- Legacy Pendants: Compatible with R-J2 and R-J3 controllers.
They are essential for robot programming, diagnostics, and maintenance operations.
Servo Motors & Amplifiers
Precision motion starts with the i and i series.
- Servo Motors: High-torque motors for axis J1 through J6.
- Servo Amplifiers: Single, Double, and Triple-axis modules (A06B series).
- Common Issue: Axis alarms? Its often time to replace the amplifier module or encoder.
Industrial Robot Cables
Our high-flex cables are designed for continuous torsional stress.
- Teach Pendant Cables: 5m, 10m, and custom lengths.
- Integrated Harnesses: Internal robot cables for M-series and R-series.
- Power & Signal Cables: Reliable connectivity between the controller and the mechanical unit.
Cable damage is a common cause of communication errors and system alarms.

4. FANUC Robot Alarm Codes
Industrial robot systems often generate alarm codes when faults occur.
Common FANUC alarms include:
SRVO-021 (SVAL1): Indicates a Servo Amplifier or Motor malfunction.
SRVO-062 (BZAL): Battery voltage drop (Time to replace the Encoder Battery).
SRVO-050:Collision Detect C Check your mechanical unit or motor torque.
COMM-101:Communication error C Inspect your I/O boards or cables.
Understanding alarm codes helps technicians diagnose problems quickly and reduce downtime.
5. FANUC Robot Controller Architecture
FANUC controllers contain several key modules that work together to control robot operation.
Typical controller architecture includes:
Main CPU Board
Controls robot programs and system management.
Servo Amplifier Module
Drives motors and controls robot axes.
Power Supply Unit
Provides stable power for controller electronics.
I/O Interface Modules
Enable communication with external devices such as PLC systems.
These modules ensure stable communication and precise robot control.
