QNK 1.5KW 2HP AC 220V VFD Converter Instruction Manual

1. הקדמה

This manual provides essential information for the safe and efficient operation of your QNK 1.5KW 2HP AC 220V Variable Frequency Drive (VFD) Converter. Please read this manual thoroughly before installation, operation, or maintenance.

2. מידע בטיחות

אַזהָרָה: Risk of electric shock. Read manual before installing. Wait 5 minutes for capacitor discharge after disconnecting power supply.

• Always wear personal protective gear (PPE) before powering up the VFD.
• Ensure the rated frequency of the motor is consistent with that of the VFD before running. Adjust parameters F005, F004, and F003 if necessary.
• The VFD cannot be used as a power source for other equipment or to drive a motor with a supply voltage נמוך מ-80V.
• Do not connect the VFD's output terminals with capacitive loads.
• For heavy equipment like cranes or compressors, choose a VFD with a larger power output (e.g., a 5.5 Kw motor should use a 7.5 Kw VFD).
• If a generator powers the VFD, ensure its output voltage is within +/-15%.

4. התקנה והתקנה

4.1 הוראות חיווט

Ensure the power is off before performing any wiring. Use proper safety equipment.

1. חוטי חשמל: For a 220V single-phase power supply, tie the power wires to the L1 and L3 terminals.
2. חוטי מנוע: Connect the three motor wires to the U, V, and W terminals.
3. Braking Resistor (Optional): This VFD supports connecting a braking resistor (not included). Connect the DC+ and DB connectors of the resistor with the VFD. A braking resistor consumes energy generated by the motor during fast braking, useful for equipment like engraving machine spindles.
4. After wiring, ensure all connections are firm and correct.

5.1 Initial Parameter Settings (for 220V 400Hz 24000RPM motor)

The VFD's default rated frequency is 50 Hz. If your motor's rated frequency is different (e.g., 400 Hz), you must adjust the following parameters:

1. Connect power to the VFD.
2. לִלְחוֹץ מַעֲרֶכֶת, נווט אל F005, and set its value to 400. לִלְחוֹץ מַעֲרֶכֶת כדי לאשר.
3. לִלְחוֹץ מַעֲרֶכֶת, נווט אל F004, and set its value to 400. לִלְחוֹץ מַעֲרֶכֶת כדי לאשר.
4. לִלְחוֹץ מַעֲרֶכֶת, נווט אל F003, and set its value to 400. לִלְחוֹץ מַעֲרֶכֶת כדי לאשר.
5. לִלְחוֹץ מַעֲרֶכֶת, נווט אל F144, and set its value to 24000 (displayed as 24.00 on screen). Press מַעֲרֶכֶת כדי לאשר.
6. Ensure the motor's rated frequency matches the inverter's rated frequency.

5.2 Adjusting Rated Frequency (Example: 60Hz Motor)

If your motor has a rated frequency of 60Hz and a rated speed of 1850 RPM, follow these steps:

1. Power on the VFD.
2. לִלְחוֹץ מַעֲרֶכֶת, נווט אל F0013, and set its value to 8. לִלְחוֹץ מַעֲרֶכֶת כדי לאשר.
3. לִלְחוֹץ מַעֲרֶכֶת, נווט אל F005, and set its value to 60. לִלְחוֹץ מַעֲרֶכֶת כדי לאשר.
4. לִלְחוֹץ מַעֲרֶכֶת, נווט אל F004, and set its value to 60. לִלְחוֹץ מַעֲרֶכֶת כדי לאשר.
5. לִלְחוֹץ מַעֲרֶכֶת, נווט אל F003, and set its value to 60. לִלְחוֹץ מַעֲרֶכֶת כדי לאשר.
6. לִלְחוֹץ מַעֲרֶכֶת, נווט אל F144, and set its value to 1850. לִלְחוֹץ מַעֲרֶכֶת כדי לאשר.
7. After setting, verify the frequency displayed on the panel is 60 Hz.

5.3 Motor Direction Adjustment

If the motor rotates in the reverse direction after initial setup, you can change its rotation by exchanging the wiring:

1. Turn off the VFD power and wait for it to fully stop.
2. Remove the cover of the VFD's terminal block.
3. Randomly exchange the locations of any two motor wires (U, V, or W) connected to the output terminals. For example, swap U and W.
4. Ensure the wires are tied firmly and replace the cover.
5. Power on the VFD and run the motor again. The motor should now rotate in the desired direction.

6. Key Features and Protection

• Low-Noise Operation & Low Electromagnetic Interference: Utilizes PMW control technology and component compatibility design.
• V/F Control & Vector Control: Frequency setting modes include digital, analog, serial communication (RS485 with MODBUS), and PID setting.
• Improved Safety & Durability: Features protective functions for overload, fuse, over voltagה (DC voltage > 400V), under voltagה (DC voltage < 200V), restart, stall, short circuit, and overheat.
