6. Mga Instruksyon sa Pag-opera
Once the VFD is correctly installed and wired, you can begin operation. Familiarize yourself with the control panel functions.
6.1 Basic nga Operasyon
- Gahum sa: Ensure all connections are secure, then apply single-phase 220V AC power to the L and N terminals. The VFD display should illuminate.
- Pagsugod sa Motor: Pindota ang
RUNbutton to start the motor. The FWD or REV indicator will light up depending on the current direction setting. - Adjust Frequency/Speed: 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).
- Usba ang Direksyon: Pindota ang
FWD/REVbutton to toggle the motor's rotation direction. - Hunonga ang Motor: Pindota ang
STOP/RESETbuton aron ihunong ang motor.
6.2 Parameter Programming
Ang PROG ug 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.
- Press
PROGto enter or exit programming mode. - Paggamit
▲ug▼to navigate through parameter groups or individual parameters. - Press
FUNC/DATAto select a parameter for editing or to confirm a value. - Use the rotary knob or arrow keys to change the parameter value.
- Press
FUNC/DATAagain to save the new value.
7. Pagmentinar
Ang regular nga pagmentinar makatabang sa pagsiguro sa kalig-on ug kasaligan nga operasyon sa imong VFD.
