Temel Bileşenler:

Figure 3: Front panel with labeled controls and display.
- Digital Display (Nixie tube): Shows the motor adjustment duty cycle, and allows setting upper/lower limits and frequency.
- Döner Kodlayıcı Düğmesi: Used to adjust motor speed. Turning left decreases the duty cycle, turning right increases it.
- Kodlayıcı Düğmesi: A short press controls motor start and stop. A long press enters the setting mode for parameters.
- Motor Start/Stop Light: Indicates motor status (light on for start, off for stop).
Kurulum ve Yükleme
Proper wiring is crucial for the safe and correct operation of the speed controller. Refer to the wiring diagram below.

Figure 4: Wiring diagram for the Voktta PWM DC Motor Speed Controller.
Kablolama talimatları:
- Güç Girişi: Connect your DC power supply (9V-60V) to the "POWER+" and "POWER-" terminals. Ensure correct polarity.
- Motor Çıkışı: Connect your DC motor to the "MOTOR+" and "MOTOR-" terminals. The motor's rotation direction can be reversed by swapping these connections.
- Harici Kontrol (İsteğe Bağlı): The unit can be connected to a switch signal or a 3.3V level signal via the J3 terminals (STOP, GND, CTRL) to control motor start and stop.
- Montaj: The controller is designed for panel mounting. Ensure adequate ventilation around the unit.
Warning: Double-check all connections before applying power to prevent damage.
Kullanım Talimatları
1. Güç Açma/Kapatma
- After wiring, apply power to the controller. The digital display will light up.
- To start the motor, short press the rotary encoder knob. The motor start light will illuminate.
- To stop the motor, short press the rotary encoder knob again. The motor start light will turn off.
2. Motor Hızının Ayarlanması
- With the motor running, turn the rotary encoder knob clockwise to increase the motor speed (increase duty cycle).
- Turn the rotary encoder knob counter-clockwise to decrease the motor speed (decrease duty cycle).
- The digital display shows the current duty cycle percentage.
3. Parameter Settings (Advanced)
To enter the parameter setting mode, long press the rotary encoder knob until the display changes.
- Setting Duty Cycle Limits:
- In setting mode, rotate the knob to select the parameter for minimum duty cycle (e.g., 'L00' for 0%). Press the knob to confirm.
- Rotate the knob to adjust the value. Press again to save and move to the next parameter.
- Repeat for maximum duty cycle (e.g., 'H100' for 100%).
- Setting PWM Output Frequency:
- In setting mode, rotate the knob to select the frequency parameter (e.g., 'F20' for 20 KHz). Press the knob to confirm.
- Rotate the knob to adjust the frequency (1 KHz to 99 KHz). The default frequency is 20 KHz. Press again to save.
- Ayarlar Modundan Çıkılıyor: Long press the rotary encoder knob again to exit the setting mode and return to normal operation.
The soft start protection feature automatically reduces the initial current surge, protecting the motor and extending its lifespan.

Bakım
- Kumanda ünitesini temiz tutun ve tozdan ve kirden arındırın. Temizlik için yumuşak, kuru bir bez kullanın.
- Tüm kablo bağlantılarını düzenli olarak kontrol ederek sağlam ve korozyondan arınmış olduklarından emin olun.
- Avoid exposing the device to direct sunlight or high humidity for extended periods.
- C'yi açmaya çalışmayınasing or modify the internal circuitry, as this will void any warranty and may cause damage or injury.
Sorun giderme
| Sorun | Olası Neden | Çözüm |
|---|---|---|
| Kumanda açılmıyor. | No power supply, incorrect wiring, or reverse polarity. | Güç kaynağı bağlantısını ve hacmini kontrol edintage. Verify wiring polarity. |
