4. Configuração
Proper installation is crucial for the inverter's performance and longevity. Follow these general guidelines:
- Montagem: 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).
- Fiação de energia: Connect the 3-phase power supply (380-500V) to the designated input terminals (R, S, T). Ensure correct phase sequence.
- Fiação do 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.
- Aterramento: Conecte o terminal de aterramento do inversor a um aterramento confiável.
- 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.
- Inicialização inicial: Before applying power, double-check all wiring connections for security and correctness.
5. Instruções de operação
This section outlines basic operation. Refer to the comprehensive technical manual for advanced programming and parameter settings.
- Ligar: 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.
- Ajuste de velocidade:
- Controle local: Rotate the control panel's knob to adjust the output frequency (motor speed).
- Controle externo: If configured, use an external potentiometer or analog input signal to control speed.
- Iniciar/Parar:
- Controle local: Press the "RUN" button (if available on the panel) or configure a digital input for start/stop.
- Controle externo: Use a digital input signal (e.g., from a PLC or switch) to start and stop the motor.
- Monitoramento: 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.
- Desligar: To shut down, stop the motor, then disconnect the main power supply to the inverter.
6. Manutenção
Regular maintenance ensures optimal performance and extends the lifespan of your inverter. Always disconnect power before performing any maintenance.
- Limpeza: 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.
- Inspeção: Inspecione regularmente as conexões da fiação para verificar se estão bem apertadas e se apresentam sinais de desgaste ou danos. Verifique se há ruídos ou odores incomuns durante o funcionamento.
- Verificação ambiental: Assegurar que o ambiente operacional permaneça dentro das faixas de temperatura e umidade especificadas.
- Verificação do ventilador: If equipped with cooling fans, ensure they are operating freely and are not obstructed.
