5. Setup and Wiring

Proper wiring is crucial for the safe and correct operation of the VFD. Refer to the wiring diagram below and ensure all connections are secure and meet local electrical codes.

Figure 5.1: Wiring Diagram. This diagram illustrates the connection points for the SU600 VFD. It shows the single-phase 220V input power connection (R, S/L1/L2), the three-phase 380V output power connection to the motor (U, V, W), the ground wire, and optional connections for a brake resistor (P+, PB).

Wiring Steps:

1. Input Power Connection: Connect the single-phase 220V AC power supply to terminals R and S/L1/L2. Ensure the power source is properly fused and switched.
2. Motor Connection: Connect the three-phase motor to the output terminals U, V, and W. Verify the motor's voltage and current ratings are compatible with the VFD's output.
3. Grounding: Connect the ground wire from both the power supply and the motor to the VFD's ground terminal. Proper grounding is essential for safety.
4. Brake Resistor (Optional): If a brake resistor is required for your application (e.g., for CNC machine tools), connect it to terminals P+ and PB.
5. External Operation Panel (Optional): If using an external operation panel, connect it to the external network port as shown in the operating interface diagram.

6. Operating Instructions

The SU600 VFD features an intuitive control panel for easy operation and parameter adjustment.

Figure 6.1: Operation and Display Interface. This image details the VFD's control panel, showing the digital display, programming key (PRG), confirm key (ENT), run key (RUN), stop key (STOP), incremental key (up arrow), and decrement key (down arrow). It also indicates the external network port and an optional external operation panel.

Control Panel Functions:

• PRG (Programming Key): Enters or exits parameter programming mode.
• ENT (Confirm Key): Confirms parameter settings or enters sub-menus.
• RUN (Run Key): Starts the motor.
• STOP (Stop Key): Stops the motor.
• Up/Down Arrows (Incremental/Decrement Keys): Adjusts frequency, navigates menus, or changes parameter values.
• Display: Shows current frequency, current, voltage, and fault indicators (FWD, REV, ALM).

Basic Operation:

1. Power On: After ensuring all wiring is correct and secure, apply power to the VFD. The display will light up.
2. Set Frequency: Use the Up/Down arrow keys to set the desired output frequency.
3. Start Motor: Press the RUN button to start the motor. The display will show the operating frequency and other relevant parameters.
4. Stop Motor: Press the STOP button to stop the motor.
5. Parameter Adjustment: To change advanced settings, press the PRG key to enter programming mode. Use the Up/Down keys to navigate parameters and ENT to confirm changes. Refer to the full product manual for detailed parameter descriptions.

7. Maintenance

Regular maintenance ensures the longevity and reliable operation of your SU600 VFD.

• Cleaning: Periodically clean the VFD's exterior and cooling fins to prevent dust accumulation, which can hinder heat dissipation. Use a soft, dry cloth. Do not use liquid cleaners.
• Inspection: Regularly inspect all wiring connections for tightness and signs of wear or damage. Check for any unusual noises or odors during operation.
• Environment: Ensure the operating environment remains within the specified temperature and humidity ranges. Keep the VFD away from direct sunlight, excessive vibration, and corrosive substances.
• Fan Check: Verify that the cooling fan operates freely and is not obstructed.
