2. Safety Information
WARNING:
- Always read this user manual thoroughly before operating the VFD. Failure to do so may result in serious injury or equipment damage.
- Risk of Electrical Shock: This device operates with high voltage. To prevent electrical shock, wait at least 10 minutes after disconnecting all power sources before performing any servicing or inspection. Verify that all capacitors are discharged before touching any components.
- Incorrect Wiring Hazard: Do not connect AC power directly to the output terminals (U/T1, V/T2, and W/T3) of the VFD. These terminals are exclusively for connecting to the motor. Connecting AC power to these terminals will cause severe damage to the VFD.

- ENTER Button: Confirms parameter settings or enters sub-menus.
- Up/Down Arrows (▲ / ▼): Used to navigate through parameters or adjust values.
- Left/Right Arrows (< / >): Used to shift digits when entering numerical values or navigate between parameter digits.
6.2 Basic Operation Steps
- Power On: Apply 3-phase 230VAC power to the VFD. The display will illuminate.
- Parameter Setting: Use the MODE and arrow buttons to navigate to the desired parameter group (e.g., frequency setting, acceleration/deceleration times). Use ENTER to select, adjust values with Up/Down, and confirm with ENTER. Refer to the detailed parameter manual for specific settings.
- Start Motor: Press the RUN button. The motor will accelerate to the set frequency.
- Stop Motor: Press the STOP/RESET button. The motor will decelerate and stop.
7. Maintenance
Regular maintenance ensures the longevity and reliable operation of your VFD.
- Cleaning: Periodically clean the VFD's exterior and ventilation openings to prevent dust accumulation, which can impede cooling. 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.
- Ventilation: Ensure that the VFD's cooling fans are operating correctly and that airflow is not obstructed. Maintain adequate clearance around the unit as specified in the installation section.
- Capacitor Life: Electrolytic capacitors have a finite lifespan. While designed for long life, consider professional inspection or replacement after several years of continuous operation, especially in high-temperature environments.
8. Troubleshooting
This section provides basic troubleshooting steps for common issues. For complex problems or persistent faults, contact technical support.
| Problem | Possible Cause | Solution |
|---|---|---|
| VFD does not power on | No input power; Blown fuse; Internal fault | Check input power supply and fuses. Ensure connections are secure. If problem persists, contact support. |
| Motor does not run | VFD in STOP mode; Fault code active; Incorrect parameter settings; Motor wiring issue | Press RUN button. Check display for fault codes and refer to manual for specific code solutions. Verify motor wiring and parameter settings (e.g., frequency command, run command source). |
| Overcurrent fault (OC) | Motor overload; Short circuit in motor wiring; Rapid acceleration/deceleration; Incorrect motor parameters | Check motor load. Inspect motor wiring for shorts. Adjust acceleration/deceleration times. Verify motor parameters (e.g., motor rated current, auto-tuning). |
| Overvoltage fault (OV) | Rapid deceleration; High input voltage; Regenerative load | Increase deceleration time. Check input voltage. Consider adding an external braking resistor if regenerative load is present. |
| Overheat fault (OH) | Insufficient ventilation; Ambient temperature too high; Cooling fan failure | Ensure adequate airflow around VFD. Reduce ambient temperature if possible. Check cooling fan operation. Clean heatsink. |
Always refer to the complete VFD manual for a comprehensive list of fault codes and detailed troubleshooting procedures.
