소개
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.

안전 정보
- 전원 공급 장치 볼륨을 확인하십시오.tage is within the specified range (DC 9V-60V) to prevent damage to the controller and motor.
- Always disconnect power before making any wiring connections or disconnections.
- 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.
- 기기를 습기, 먼지, 극한 온도에 두지 마세요.
- This product is intended for industrial and hobbyist use. Professional installation is recommended if you are unfamiliar with electrical wiring.

주요 구성 요소:
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.
- 로터리 엔코더 노브: Used to adjust motor speed. Turning left decreases the duty cycle, turning right increases it.
- 인코더 버튼: 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).
설정 및 설치
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.
배선 지침:
- 전원 입력: Connect your DC power supply (9V-60V) to the "POWER+" and "POWER-" terminals. Ensure correct polarity.
- 모터 출력: Connect your DC motor to the "MOTOR+" and "MOTOR-" terminals. The motor's rotation direction can be reversed by swapping these connections.
- 외부 제어(선택 사항): 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.
- 설치: The controller is designed for panel mounting. Ensure adequate ventilation around the unit.
Warning: Double-check all connections before applying power to prevent damage.
작동 지침
1. 전원 켜기/끄기
- 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. 모터 속도 조절
- 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.
- 설정 모드 종료: 설정 모드를 종료하고 일반 작동 모드로 돌아가려면 로터리 엔코더 노브를 다시 길게 누르십시오.
The soft start protection feature automatically reduces the initial current surge, protecting the motor and extending its lifespan.
