ABB 3HAC13389-2 Axis Computer Board for ABB IRC5 Industrial Robot Controller

1. Basic Information

2. Electrical & Interface Specifications

• Main function: Real‑time axis motion control, position closed‑loop calculation, servo command generation
• Interfaces: Internal backplane bus to main controller unit; fibre‑optic links for servo drive communication
• Supported axes: Handles multiple robot joint axes position and speed feedback processing
• Diagnostics: Overload monitoring, position error tracking, hardware fault detection; fault codes reported to RobotStudio
• Galvanic isolation via fibre‑optic links between control board and servo power units
• Firmware: Robot controller system firmware downloaded from main IRC5 controller

3. Environmental Conditions

• Operating temperature: 0 ℃ ~ +55 ℃ (inside robot controller cabinet)
• Storage temperature: ‑40 ℃ ~ +85 ℃
• Relative humidity: 5‑95 % RH, non‑condensing
• Approvals & standards: CE, UL, IEC 61010‑1, IEC 61508 relevant industrial robot standards
• Enclosure rating: IP00; protected by IRC5 controller cabinet enclosure

4. Main Functions

1. Executes real‑time position‑loop and speed‑loop control for robot joint axes within IRC5 controller.
2. Transmits motion commands to servo drives and receives encoder position feedback via optical communication.
3. Monitors axis following error, speed and torque status; triggers safety stop when abnormal conditions occur.
4. Communicates with main controller board through internal backplane bus, exchanges motion parameters and fault information.
5. Works as key motion‑control hardware for ABB IRB‑series industrial robots with IRC5 controller.
6. Product lifecycle status: Obsolete, original manufacturing discontinued; only spare‑part or used surplus stock available.

5. Typical Applications

1. ABB IRC5 controller for IRB series 6‑axis industrial robots used in welding, handling, assembly and painting production lines.
2. Replacement spare part for failed axis computer boards on existing installed robot systems.

6. Important Notes

1. Strictly dedicated for ABB IRC5 robot controller platform; cannot be used for general‑purpose PLC or DCS applications.
2. Board replacement requires robot system firmware matching; firmware version incompatibility causes motion failure or hardware damage.
3. Electrostatic‑sensitive component; ESD protection measures must be followed during handling and installation.
4. Fault diagnosis and configuration must be completed via RobotStudio software tool.
5. Full ordering part‑number 3HAC13389‑2 must be used for spare‑part procurement.
