6. Istruzzjonijiet Operattivi
Once the VFD is correctly installed and wired, you can begin operation. Familiarize yourself with the control panel functions.
6.1 Operazzjoni Bażika
- Qawwa Mixgħul: Ensure all connections are secure, then apply single-phase 220V AC power to the L and N terminals. The VFD display should illuminate.
- Ibda l-Mutur: Agħfas il-
RUNbutton to start the motor. The FWD or REV indicator will light up depending on the current direction setting. - Aġġusta l-Frekwenza/Veloċità: Use the rotary knob to adjust the output frequency, which in turn controls the motor speed. The display will show the current frequency (Hz) or RPM (r/min).
- Ibdel id-direzzjoni: Agħfas il-
FWD/REVbutton to toggle the motor's rotation direction. - Waqqaf il-Mutur: Agħfas il-
STOP/RESETbuttuna biex twaqqaf il-mutur.
6.2 Programmazzjoni tal-Parametri
Il- PROG u FUNC/DATA buttons, along with the arrow keys (▲, ▼), are used to access and modify various operating parameters. Refer to the detailed programming manual (if available) for specific parameter settings relevant to your application.
