4. Configuració
Una instal·lació correcta és crucial per al rendiment i la longevitat de l'inversor. Seguiu aquestes pautes generals:
- Muntatge: Mount the inverter vertically on a flat, stable surface, ensuring adequate clearance for ventilation (at least 10 cm above and below, and 5 cm on the sides).
- Cablejat d'alimentació: Connect the 3-phase power supply (380-500V) to the designated input terminals (R, S, T). Ensure correct phase sequence.
- Cablejat del motor: Connect the motor to the output terminals (U, V, W). Verify that the motor's voltage and current ratings match the inverter's output capabilities.
- Posada a terra: Connect the ground terminal of the inverter to a reliable earth ground.
- Control Wiring (Optional): If using external control signals (e.g., start/stop, speed reference), connect them to the appropriate control terminals as per the detailed wiring diagram in the full technical manual.
- Engegada inicial: Before applying power, double-check all wiring connections for security and correctness.
5. Instruccions de funcionament
This section outlines basic operation. Refer to the comprehensive technical manual for advanced programming and parameter settings.
- Encès: Apply main power to the inverter. The display will illuminate, indicating readiness.
- Parameter Setting (Initial): Use the rotary knob and ESC button on the control panel to navigate menus and set essential parameters such as motor nominal frequency, maximum output frequency, and acceleration/deceleration times. Consult the full manual for parameter codes.
- Ajust de velocitat:
- Control local: Rotate the control panel's knob to adjust the output frequency (motor speed).
- Control extern: If configured, use an external potentiometer or analog input signal to control speed.
- Inici/Parada:
- Control local: Press the "RUN" button (if available on the panel) or configure a digital input for start/stop.
- Control extern: Use a digital input signal (e.g., from a PLC or switch) to start and stop the motor.
- Seguiment: The display can show various operational parameters such as output frequency, output current, output voltage, and motor speed. Use the MON button to cycle through monitoring displays.
- Apagar: To shut down, stop the motor, then disconnect the main power supply to the inverter.
6. Manteniment
Regular maintenance ensures optimal performance and extends the lifespan of your inverter. Always disconnect power before performing any maintenance.
- Neteja: Periodically clean the inverter's exterior and ventilation grilles to prevent dust accumulation, which can impede cooling. Use a soft, dry cloth. Do not use liquid cleaners.
- Inspecció: Regularly inspect wiring connections for tightness and signs of wear or damage. Check for any unusual noises or odors during operation.
- Control ambiental: Assegureu-vos que l'entorn de funcionament es mantingui dins dels rangs de temperatura i humitat especificats.
- Comprovació del ventilador: If equipped with cooling fans, ensure they are operating freely and are not obstructed.
