Einführung
This manual provides comprehensive instructions for the Voktta PWM DC Motor Speed Controller, Model VKXN0029. This device is designed to regulate the speed of DC motors by adjusting the Pulse Width Modulation (PWM) signal. It is suitable for DC motors operating within a voltage range of 9V to 60V and a maximum power output of 500W. Key features include soft start protection, a digital encoder knob for precise control, and adjustable duty cycle and frequency settings.
Bitte lesen Sie diese Bedienungsanleitung vor der Installation und Inbetriebnahme sorgfältig durch, um eine sichere und effiziente Nutzung des Produkts zu gewährleisten.
Sicherheitshinweise
- Stellen Sie sicher, dass die Stromversorgungslautstärketage is within the specified range (DC 9V-60V) to prevent damage to the controller and motor.
- Vor dem Anschließen oder Trennen von Kabeln muss immer die Stromzufuhr unterbrochen werden.
- Observe correct polarity when connecting the power supply and motor. Reverse polarity can cause irreversible damage.
- Do not exceed the maximum rated current of 20A or maximum power of 500W.
- Das Gerät sollte vor Feuchtigkeit, Staub und extremen Temperaturen geschützt werden.
- This product is intended for industrial and hobbyist use. Professional installation is recommended if you are unfamiliar with electrical wiring.

Schlüsselkomponenten:

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.
- Rotary Encoder Knob: Used to adjust motor speed. Turning left decreases the duty cycle, turning right increases it.
- Encoder-Taste: 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).
Setup und Installation
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.
Verkabelungsanleitungen:
- Leistungsaufnahme: Connect your DC power supply (9V-60V) to the "POWER+" and "POWER-" terminals. Ensure correct polarity.
- Motorleistung: Connect your DC motor to the "MOTOR+" and "MOTOR-" terminals. The motor's rotation direction can be reversed by swapping these connections.
- Externe Steuerung (optional): 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.
- Montage: The controller is designed for panel mounting. Ensure adequate ventilation around the unit.
Warning: Double-check all connections before applying power to prevent damage.
Bedienungsanleitung
1. Ein-/Ausschalten
- 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. Adjusting Motor Speed
- 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.
- Einstellungsmodus verlassen: 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.

Wartung
- Halten Sie den Controller sauber und frei von Staub und Schmutz. Verwenden Sie zum Reinigen ein weiches, trockenes Tuch.
- Überprüfen Sie regelmäßig alle Kabelverbindungen, um sicherzustellen, dass sie fest sitzen und frei von Korrosion sind.
- Avoid exposing the device to direct sunlight or high humidity for extended periods.
- Versuchen Sie nicht, das Gehäuse zu öffnen.asing or modify the internal circuitry, as this will void any warranty and may cause damage or injury.
Fehlerbehebung
| Problem | Mögliche Ursache | Lösung |
|---|---|---|
| Der Controller lässt sich nicht einschalten. | No power supply, incorrect wiring, or reverse polarity. | Überprüfen Sie den Netzteilanschluss und die Lautstärke.tage. Verify wiring polarity. |
| Motor läuft nicht. | Motor not connected, motor stop engaged, or duty cycle set to 0%. | Ensure motor is connected. Short press the knob to start the motor. Increase duty cycle. |
| Die Motordrehzahl kann nicht angepasst werden. | Knob malfunction or in setting mode. | Ensure not in setting mode (long press to exit). Check knob for physical damage. |
| Motor runs erratically. | Unstable power supply or loose connections. | Verify power supply stability. Check all wiring connections for tightness. |
