1. Introduction
The SUSWE SU600 Series Variable Frequency Drive (VFD) is an economical and efficient solution designed for controlling the speed of AC motors. It converts 220V single-phase or three-phase input to 380V three-phase output, or 220V single-phase to 220V three-phase output, providing precise control over motor operations. This manual provides essential information for the safe and effective installation, operation, and maintenance of your VFD.

4. Setup
4.1. Physical Installation
Mount the VFD in a location that allows for adequate airflow to prevent overheating. Ensure the mounting surface is stable and free from vibrations. The VFD is designed with waterproof, moisture-proof, and mildew-proof main board materials for enhanced durability.
4.2. Wiring Diagram
Follow the wiring diagram carefully. Incorrect wiring can damage the VFD or connected equipment.
- Input Power Connection (R, S/L1, T/L2): Connect your main power supply to these terminals. Ensure the circuit breaker is installed upstream for protection.
- Output Power Connection (U, V, W): Connect these terminals directly to your three-phase induction motor.
- Ground Wire: Connect the ground terminal to a reliable earth ground.
- Brake Resistor Connection (P+, PB): If required for your application (e.g., CNC machine tools), connect a brake resistor to these terminals.
- Multifunctional Input Terminals (X1, X2, X3, X4, COM): These terminals are for external control signals.
- External Keyboard Interface (J11): For connecting an external operation panel.
- Analog Input (AI, GND): For connecting a potentiometer (e.g., SK-10K) or other analog signal sources (DC 0-10V / DC 0-20mA) for speed control.
- Analog Output (AO, GND): Provides an analog output signal (DC 0-10V / 0-20mA).
- RS485 Communication (485+, 485-): For serial communication.
- Relay Output (TA, TC): Provides a relay contact for external control.
4.3. External Operation Panel
The VFD supports an external operation panel for remote control and monitoring. Connect the external panel to the VFD's external network port using a suitable cable.
5. Operating Instructions
5.1. Control Panel Overview
The VFD features a user-friendly control panel with a digital display and various buttons for operation and programming.
- PRG (Programming Key): Enters/exits programming mode.
- ENT (Confirm Key): Confirms parameter settings or enters sub-menus.
- RUN (Run Key): Starts the motor.
- STOP/RST (Stop/Reset Key): Stops the motor or resets fault alarms.
- Knob (Incremental/Decrement Key): Adjusts frequency, parameter values, or navigates menus.
- Indicators: FWD/REV (direction), Hz (frequency), A (current), ALM (alarm/fault), V (voltage).
5.2. Basic Operation
- Power On: Ensure all wiring is correct and secure, then apply power to the VFD. The display will light up.
- Frequency Adjustment: Use the knob to adjust the desired output frequency.
- Start Motor: Press the RUN button to start the motor.
- Stop Motor: Press the STOP/RST button to stop the motor.
5.3. Programming
For advanced settings and parameter adjustments, press the PRG key to enter programming mode. Use the knob to navigate through parameters and the ENT key to select and confirm values. Refer to the detailed programming manual (if provided separately) for specific parameter codes and their functions.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your VFD.
- Cleaning: Keep the VFD clean and free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
- Ventilation: Ensure cooling fans are unobstructed and functioning correctly. Periodically clean fan grilles.
- Environmental Conditions: The VFD's main board is designed to be waterproof, moisture-proof, and mildew-proof, but it is still recommended to operate it in a clean, dry environment within specified temperature and humidity ranges.
- Connection Checks: Periodically inspect all wiring connections for tightness and signs of wear or corrosion.
- Firmware Updates: Check the manufacturer's website for any available firmware updates.
7. Troubleshooting
If you encounter issues with your VFD, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor does not start | Incorrect wiring, no power, fault condition, parameter error | Check wiring, verify power supply, check ALM indicator for fault codes, review motor parameters. |
| Motor speed is incorrect | Frequency setting error, motor parameters incorrect | Adjust frequency using the knob, verify motor nameplate data matches VFD parameters. |
| VFD displays an alarm (ALM) | Overcurrent, overvoltage, undervoltage, overheating, external fault | Note the specific fault code displayed, consult the full manual for code meaning, and address the underlying issue. Press STOP/RST to clear. |
| External panel not responding | Cable connection issue, panel fault | Check the connection cable between the VFD and the external panel. Ensure the panel is correctly installed. |
