4. Орнотуу

4.1 Монтаждоо

The VFD should be mounted vertically in a well-ventilated area, away from direct sunlight, excessive dust, moisture, and corrosive gases. Ensure sufficient clearance around the unit for proper heat dissipation.

• Орнотуу көлөмү: 130мм × 73мм
• Өлчөмдөрү: 145mm (H) × 110mm (W) × 85mm (D)
• Use appropriate screws to secure the VFD to a stable surface.

4.2 Электр зымдары

IMPORTANT: Ensure power is OFF before wiring. Incorrect wiring can damage the VFD and motor.

Refer to the wiring diagram below for proper connections. Use appropriate wire gauges for the rated current.

Figure 4.2.1: Wiring diagram for the SAKO SKI780 VFD. R, S, T are for single-phase 220V input. U, V, W are for three-phase 220V motor output. P+ and PB are for braking resistor connections if applicable.

• Киргизүү кубаттуулугу (R, S, T): Connect single-phase 220V AC power to terminals R and S. Terminal T is typically not used for single-phase input, or can be connected to S for some configurations. Refer to specific product labeling.
• Мотордун чыгышы (U, V, W): Connect the three-phase motor to terminals U, V, and W. Ensure correct phase sequence for desired motor rotation.
• Жер (PE): Жерге туташтыргычты ишенимдүү жерге туташтыргычка туташтырыңыз.
• Braking Resistor (P+, PB): If a braking resistor is required for applications with high inertia loads, connect it to P+ and PB terminals.

5. Орнотуу

After successful wiring, proceed with initial setup. The specific parameters may vary, but common initial settings include motor parameters and control mode.

1. Күйгүзүү: Apply single-phase 220V power to the VFD. The digital display should light up.
2. Initial Parameter Check: басыңыз ПРОГ button to enter parameter setting mode. Use the Up/Down arrows to navigate through parameters.
3. Мотор параметрлери: Set the motor's rated power (KW), rated voltage (V), rated current (A), and rated frequency (Hz) according to the motor's nameplate. These are crucial for optimal performance and protection.
4. Башкаруу режими: Select the desired control mode (e.g., V/F control for general applications).
5. Max/Min Frequency: Set the maximum and minimum output frequencies as required by your application.
6. Acceleration/Deceleration Time: Adjust these parameters to control how quickly the motor speeds up or slows down.
7. Жөндөөлөрдү сактоо: After adjusting parameters, ensure they are saved (refer to the VFD's specific parameter saving procedure, usually by pressing ENTER or PROG again).

6. Иштөө

Once the VFD is installed and set up, you can begin operation.

1. Моторду ишке киргизүү: басыңыз RUN button. The VFD will accelerate the motor to the set frequency based on the acceleration time.
2. Жыштыкты жөндөө: In running mode, use the Up/Down arrows to adjust the output frequency, thereby changing the motor speed.
3. Моторду токтотуу: басыңыз STOP/REST button. The VFD will decelerate the motor to a stop based on the deceleration time.
4. Ката калыбына келтирүү: If a fault occurs, the VFD display will show an error code. After resolving the issue, press the STOP/REST button to reset the fault.

For advanced operation modes (e.g., external terminal control, multi-speed operation), refer to the detailed programming manual for the SAKO SKI780 series.

7. Техникалык тейлөө

Regular maintenance ensures the longevity and reliable operation of your VFD.

• Тазалоо: Periodically clean the VFD's exterior and cooling fins to prevent dust accumulation, which can hinder heat dissipation. Use a soft, dry cloth. Do not use liquid cleaners.
• Текшерүү: Regularly inspect wiring connections for looseness or signs of overheating. Check for any unusual noises or smells during operation.
• Курчап турган чөйрө: Иштөө чөйрөсү белгиленген температуранын жана нымдуулуктун чегинде болушун камсыз кылыңыз.
• Fan Check: Verify that the cooling fan (if present) is operating correctly and not obstructed.
• Конденсатордун иштөө мөөнөтү: Electrolytic capacitors have a finite lifespan. While not user-serviceable, be aware that performance may degrade over many years of continuous operation.

WARNING: Disconnect all power and wait for capacitor discharge before performing any maintenance inside the VFD.
