• Supported I/O Networks: Fanuc Model A, Fanuc Process I/O, Fanuc I/O Link, DeviceNet, Ethernet IP, Interbus, CC-Link, and Profinet.

Safety and Maintenance

Note: Before opening the cabinet. Maintenance should only be performed by qualified personnel.

Staying Safe During Inspection When inspecting the robot, be sure to

· Turn off power at the controller. · Lock out and tag out the power source at the controller according to the policies of your plant. · Turn off the compressed air source and relieve the air pressure.

· If robot motion is not needed for inspecting the electrical circuits, press the EMERGENCY STOP button on the operator panel.

· Never wear watches, rings, neckties, scarves, or loose clothing that could get caught in moving machinery.

· If power is needed to check the robot motion or electrical circuits, be prepared to press the EMERGENCY STOP button, in an emergency.

· Be aware that when you remove a servomotor or brake, the associated robot arm will fall if it is not supported or resting on a hard stop. Support the arm on a solid support before you release the brake.

The R-30iB and R-30iB Mate controllers prioritize safety with features like the E-stop and mode selector switches. Regular maintenance, such as checking the fuses and ensuring proper heat exchange, is essential for optimal performance.

Opening the Cabinet

When accessing the internal components, always prioritize safety:

1. Power Off: Ideally, power off the controller before opening the cabinet.
2. Use a Screwdriver: (I would rewrite this statement) In some cases, you may need to open the cabinet while the robot is running for troubleshooting. Use a flathead screwdriver to open the cabinet carefully.
3. Be Cautious: Remember, there are live circuits inside. Always follow your companies Lockout/Tagout procedures. Handle with care to avoid shock hazards.

Troubleshooting and Diagnostics

Understanding the internal layout of these controllers aids in effective troubleshooting. For instance:

• LED Indicators: Help identify faults quickly.
• Ethernet Ports: Useful for network diagnostics and FTP connections.
• PROFINET and Fuses: Ensure communication and safety circuits are functioning correctly.
