This image displays the blue casing of the VFD, with the integrated control panel featuring a digital display, various buttons (PRG/ESC, RD/WT, RUN, STOP/RESET, arrow keys), and a rotary knob. Below the main unit, a green terminal block for wiring connections is visible.

Karakteristik kle:

• Konsepsyon kontra enfòmèl ant pou enstalasyon ekonomize espas.
• Supports 3-phase motors with 220V or 380V input/output (model dependent).
• Integrated control panel with digital display.
• Plizyè fonksyon pwoteksyon (surkouran, survòl)tage, undervoltage, surcharge, elatriye).
• Adjustable frequency range for precise speed control.

3. Enstalasyon ak Enstalasyon

3.1 Montaj

Mount the VFD vertically on a stable, non-flammable surface. Ensure adequate clearance around the unit for proper ventilation and heat dissipation. Avoid mounting near heat sources or in direct sunlight. The ambient temperature should be within the specified operating range (typically -10°C to 40°C).

3.2 fil elektrik

All wiring must comply with local and national electrical codes. Use appropriate wire gauges for the VFD's power rating. Ensure all connections are secure to prevent loose contacts, which can cause malfunctions or damage.

• Power Input (R, S, T or L1, L2, L3): Connect the 3-phase AC power supply to these terminals. Ensure the voltage matches the VFD's input rating (e.g., 220V or 380V).
• Sòti Motè (U, V, W): Connect the 3-phase motor leads to these terminals. Do not connect the motor's ground wire to these terminals; connect it to the VFD's ground terminal.
• Tè (PE): Connect the VFD's ground terminal to a reliable earth ground. The motor frame should also be grounded.
• Tèminal kontwòl: These terminals are used for external control signals such as start/stop, speed reference (analog input), and fault indication. Refer to the detailed wiring diagram in the full product manual for specific connections.

4. Operasyon Enstriksyon

4.1 Kontwòl Panel Overview

Figure 4.1: SKI780 Mini VFD Control Panel. This image shows the front keypad of the VFD, featuring a digital LED display, various function buttons (PRG/ESC, RUN, STOP/RESET, RD/WT, MF.K REV), and directional arrow keys for navigation and parameter adjustment.

• Ekspozisyon: Shows operating frequency, output current, voltage, ak valè paramèt yo.
• Bouton KOURI: Kòmanse motè a.
• Bouton STOP/RESET: Stops the motor or clears fault indications.
• PRG/ESC Button: Enters/exits parameter setting mode or cancels current operation.
• RD/WT Button: Reads or writes parameter values.
• Bouton flèch monte/desann: Used to navigate through parameters or adjust values.
• Left/Right Arrow Buttons (or Rotary Knob): Used to shift digits during parameter editing or select menu items.

4.2 Operasyon debaz

1. Pouvwa sou: After ensuring all wiring is correct and secure, apply power to the VFD. The display will light up.
2. Mete frekans: Use the PRG/ESC button to enter parameter mode. Navigate to the frequency setting parameter (e.g., F0.01 or similar, refer to the full manual for exact parameter codes). Use the arrow keys to adjust the desired output frequency. Press RD/WT to save.
3. Kòmanse motè: Peze a KOURI button. The motor should start and accelerate to the set frequency.
4. Ajiste vitès: While the motor is running, you can typically adjust the frequency using the arrow keys or rotary knob directly, depending on the VFD's configuration.
5. Sispann motè a: Peze a SISPANN / Reyajiste bouton. Motè a ap ralanti epi li ap rete.

4.3 Anviwònman Paramèt

The VFD has numerous parameters that can be configured to optimize performance for specific applications. These include acceleration/deceleration times, motor parameters, control modes, and protection settings. Refer to the comprehensive parameter list in the complete user manual for detailed explanations and adjustment procedures.

5. Antretyen

Regular maintenance ensures the longevity and reliable operation of your VFD. Always disconnect power before performing any maintenance tasks.

• Netwayaj: Netwaye deyò VFD a ak alet refwadisman yo detanzantan pou anpeche pousyè akimilasyon, sa ki ka anpeche chalè disparèt. Sèvi ak yon twal mou epi sèk. Pa sèvi ak pwodui netwayaj likid.
• Enspeksyon: Regularly check for loose wiring connections, signs of overheating (discoloration), or unusual noises.
• Verifikasyon Vantilatè: Ensure the cooling fan operates freely and is not obstructed. Replace if noisy or not functioning.
• Kondisyon anviwònman: Verify that the operating environment remains within specified temperature and humidity limits.
