5.2 Wiring
All wiring must be performed by a qualified electrician. Ensure the main power supply is disconnected before making any connections.
- Power Input (R, S, T): Connect the 380V 3-phase AC power supply to the R, S, and T terminals.
- Motor Output (U, V, W): Connect the 3-phase motor to the U, V, and W terminals.
- Braking Resistor (P+, PB): If a braking resistor is required for dynamic braking, connect it to the P+ and PB terminals.
- Grounding: Ensure the VFD is properly grounded to prevent electrical shock and reduce electromagnetic interference.
- Control Terminals: Connect external control signals (e.g., start/stop, speed reference, fault reset) to the designated control terminals as per your application requirements. Refer to the detailed wiring diagram in the full manual for specific terminal functions.

6. Operating Instructions
6.1 Basic Operation
- Power On: After ensuring all wiring is correct and secure, apply power to the VFD. The display will illuminate.
- Parameter Setting (if necessary): Use the PRG (Program) key to enter the parameter setting mode. Navigate through parameters using the Up/Down keys and adjust values with the Movement keys or Speed Control Knob. Press ENTER to confirm changes. Refer to the detailed programming manual for specific parameter descriptions.
- Start Motor: Press the green RUN button on the control panel to start the motor.
- Adjust Speed: Rotate the Speed Control Knob to increase or decrease the motor speed. The display will show the current output frequency or speed.
- Stop Motor: Press the red STOP/RESET button to stop the motor.
- Reset Fault: If a fault occurs, the VFD will display an error code. After addressing the cause of the fault, press the STOP/RESET button to clear the error and reset the VFD.
7. Maintenance
Regular maintenance ensures the longevity and reliable operation of your 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.
- Fan Inspection: Check the cooling fan for proper operation and ensure it is free from obstructions. Replace if noisy or not functioning correctly.
- Terminal Tightness: Annually check all wiring terminals for tightness. Loose connections can cause overheating and damage.
- Environmental Check: Ensure the operating environment remains within specified temperature and humidity ranges.
- Capacitor Life: Electrolytic capacitors have a finite lifespan. Consider professional inspection or replacement after several years of continuous operation.
Always disconnect power and wait 10 minutes before performing any maintenance.
8. Troubleshooting
This section provides general troubleshooting tips for common issues. For complex problems, consult a qualified technician.
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor does not start | No power, incorrect wiring, fault condition, parameter error | Check power supply, verify wiring, clear fault, check motor parameters. |
| VFD displays an error code | Overcurrent, overvoltage, overheating, overload, undervoltage | Identify error code from full manual, address underlying issue (e.g., motor load, power supply), then press STOP/RESET. |
| Motor speed unstable | Incorrect PID settings, motor tuning issues, unstable load | Adjust PID parameters, perform auto-tuning if available, check motor and load conditions. |
| Excessive noise or vibration | Motor imbalance, mechanical issues, VFD switching frequency | Check motor and load for mechanical problems, adjust VFD carrier frequency (if applicable and within limits). |
