- SET/SHIFT: Confirms parameter settings, shifts cursor during input.
4. Configuració i instal·lació
4.1. Muntatge
Mount the frequency converter vertically on a flat, non-flammable surface. Ensure adequate ventilation space around the unit (at least 10 cm above and below, 5 cm on sides) for heat dissipation.
4.2. Cablatge
Refer to the wiring diagram provided with your specific model for detailed connections. General wiring guidelines:
- Entrada d'alimentació (R, S, T o L1, L2): Connect to the main power supply. Ensure correct voltage (220V or 380V depending on model).
- Sortida del motor (U, V, W): Connecteu-ho als terminals del motor.
- Terra (PE): Connecteu-vos a un punt de terra fiable.
- Terminals de control: For external control signals (e.g., start/stop, speed reference, fault output).
Warning: Incorrect wiring can lead to severe damage to the unit or personal injury. Consult a qualified electrician if unsure.
5. Instruccions de funcionament
5.1. Engegada inicial
- After completing all wiring, apply power to the frequency converter.
- The display will light up, typically showing "0.00" or a default frequency.
5.2. Basic Operation (Keypad Control)
- Establir freqüència: Premeu el botó PRG button to enter parameter mode. Navigate to the frequency setting parameter (e.g., F0.01) using the Amunt/Avall fletxes. Premeu SET/SHIFT to edit, adjust value, then SET/SHIFT again to confirm. Press PRG per sortir.
- Motor d'arrencada: Premeu el botó CÓRRER botó. El motor accelerarà fins a la freqüència configurada.
- Atura el motor: Premeu el botó STOP/RESET botó. El motor desaccelerarà i s'aturarà.
5.3. Configuració dels paràmetres
The AC10 series has a comprehensive set of parameters for various functions. Refer to the detailed parameter list in the full product manual for advanced configurations (e.g., acceleration/deceleration times, motor parameters, control modes).
Exampparàmetres del fitxer:
- F0.00: Run command source (keypad, terminal, communication)
- F0.01: Frequency setting source (keypad, analog input, communication)
- F0.03: Freqüència màxima de sortida
- F0.04: Temps d'acceleració
- F0.05: Temps de desacceleració
6. Manteniment
Regular maintenance ensures the longevity and reliable operation of your frequency converter.
- Neteja: Periodically clean the cooling fins and fan to prevent dust accumulation, which can hinder heat dissipation. Use compressed air or a soft brush. Ensure power is off before cleaning.
- Comprovació del terminal: Annually check all wiring terminals for tightness. Loose connections can cause overheating or intermittent operation.
- Control ambiental: Verifiqueu que l'entorn operatiu es mantingui dins dels rangs de temperatura i humitat especificats.
- Substitució del ventilador: Cooling fans have a limited lifespan. Consider replacing them every 3-5 years, depending on operating conditions, to maintain optimal cooling.
