MELFA Programming Tools

1. RT ToolBox3

RT ToolBox3 is the primary software for MELFA robot programming, offering features like:

• Graphical Interface: Allows drag-and-drop programming and easy visualization of robot movements.
• Simulation: Test and refine programs in a virtual environment before deployment.
• Diagnostics: Troubleshoot robot issues with real-time monitoring.

2. MELFA Basic V

A structured text-based programming language specifically for MELFA robots. It provides powerful commands for:

• Motion Control: Define precise movements, including linear, joint, and circular motions.
• Condition Handling: Program conditional logic and responses to external inputs.
• Integration: Communicate with external devices and controllers.

Getting Started with MELFA Programming

1: Setup and Connection

1. Install RT ToolBox3 on your PC.
2. Connect the robot to your PC or PLC via Ethernet or other communication interfaces.
3. Configure the communication settings in RT ToolBox3.

2: Create Your First Program

1. Launch RT ToolBox3 and create a new project.
2. Add the robot model to the workspace and verify system parameters.
3. Use the graphical editor to define basic movements, such as:
   • Picking an object from a specific location.
   • Placing the object in another position.

3: Testing and Simulation

1. Use the simulation mode in RT ToolBox3 to test the program.
2. Adjust the speed, position, or motion paths as needed.
3. Resolve any errors or conflicts flagged by the diagnostic tool.

4: Deploy to the Robot

1. Upload the program to the robot’s controller.
2. Test the program in a real-world environment, ensuring safety protocols are followed.
3. Monitor the robot’s performance and make adjustments if necessary.
