4.5 Automatic Motor Parameter Tuning
For optimal vector control performance, it is essential to accurately input motor nameplate parameters. The 9600 series VFD performs automatic tuning based on these parameters. Follow these steps:
- Set the command source (P0-02) to the operation panel.
- Enter the motor parameters (type, rated power, voltage, current, frequency, speed) into the VFD.
- If the motor and load can be completely disengaged, set P1-37 to '2' (Asynchronous motor complete auto-tuning) and press the RUN key. The VFD will automatically calculate motor parameters.
- If the motor and load cannot be completely disengaged, set P1-37 to '1' (Asynchronous motor static auto-tuning) and press the RUN key.

6. Manutenzione
Una manutenzione regolare garantisce la longevità e l'affidabilità del vostro VFD.
6.1 Manutenzione ordinaria
- Controllo del motore: Regularly check for abnormal motor sounds or excessive vibrations during operation.
- Ambiente: Ensure the installation environment is stable and free from excessive dust, humidity, or corrosive gases.
- Ventola di raffreddamento: Verify that the cooling fan operates normally and is free from obstructions.
- Surriscaldamento: Monitor for any signs of VFD overheating.
- Pulizia: Keep the VFD clean. Remove dust, especially metal powder, from the surface and clear oil stains from the cooling fan.
6.2 Ispezione periodica
- Condotto dell'aria: Periodically check and clean the air ducts.
- Elementi di fissaggio: Inspect all screws for looseness.
- Corrosione: Check the VFD for any signs of corrosion.
- Terminali di cablaggio: Examine wiring terminals for signs of arcing.
- Prova di isolamento: Before measuring insulation resistance with a megameter (500 VDC recommended), disconnect the main circuit from the VFD. Do not use the megameter to test the control circuit.
6.3 Replacement of Vulnerable Components
Key components like the cooling fan and electrolytic capacitors have a limited lifespan. Their replacement schedule depends on operating conditions and maintenance.
- Cooling Fan (2-3 years): Replace if bearing is worn, blades are aging, or abnormal vibration/noise occurs.
- Electrolytic Capacitor (4-5 years): Replace if there is liquid leakage, the safe valve has projected, or if static capacitance/insulating resistance measurements are out of specification.
6.4 Storage of the AC Drive
- Store the VFD in its original packing box.
- For long-term storage (over 2 years), energize the VFD for at least 5 hours every 2 years. Gradually increase the input voltage to the rated value using a regulator.
