4. Setup

4.1 Wiring Diagram

Refer to the detailed wiring diagram provided in the separate wiring guide for your specific machine configuration. Ensure all connections are secure and correctly matched to the corresponding terminals on the DDCS V2.1 controller. Pay close attention to power supply polarity, motor driver connections (STEP/DIR), limit switches, and emergency stop circuits.

4.2 Initial Power-Up

1. After completing all wiring, double-check every connection for accuracy and security.
2. Connect the 24V DC power supply to the controller.
3. Power on the controller. The display should illuminate, and the system will initiate its boot sequence.
4. Follow any on-screen prompts for initial setup, such as language selection or axis configuration.
5. Verify that all connected motors respond correctly to manual jog commands before proceeding with automated operations.

5. Operating Instructions

5.1 User Interface Navigation

The controller's interface consists of a display screen and a keypad. Use the arrow keys to navigate menus and parameters. The 'ENTER' or 'OK' button confirms selections, and 'ESC' or 'BACK' returns to the previous screen.

5.2 Loading G-Code

1. Save your G-code file onto a USB flash drive. Ensure the file format is compatible (e.g., .nc, .tap, .gcode).
2. Insert the USB flash drive into the USB port on the controller.
3. Navigate to the 'File Management' or 'Program' menu on the controller.
4. Select the desired G-code file from the USB drive. The controller will load and display the program information.

5.3 Starting a Job

1. After loading the G-code, ensure the workpiece is properly secured and the tool is correctly installed and offset.
2. Set the workpiece origin (G54, G55, etc.) as required by your G-code program.
3. Press the 'START' button to begin the machining process.
4. Monitor the machine's operation closely. Use the 'PAUSE' button for temporary stops and 'RESET' for emergency stops or to clear errors.

5.4 Manual Control (Jogging)

Use the dedicated axis control buttons (X+, X-, Y+, Y-, Z+, Z-, A+, A-) to manually move the machine axes. Adjust the jog step size or continuous jog speed as needed through the controller's settings.

6. Maintenance

• Cleaning: Regularly clean the controller's exterior with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials. Ensure no dust or debris accumulates in the ventilation slots.
• Firmware Updates: Check the RATTMMOTOR official website periodically for firmware updates. Follow the provided instructions carefully for any update procedures.
• Connection Checks: Periodically inspect all wiring connections for looseness or damage. Tighten any loose terminals.
