5. Safety Information
Please read and adhere to the following safety warnings to prevent damage to the device or personal injury:
- Input Voltage: The input voltage must be DC 6V-60V. It is crucial to distinguish between the positive and negative poles.
- DO NOT Input 220V AC: Connecting 220V AC power will severely damage the controller and may pose a safety hazard.
- Voltage Matching: The input voltage supplied to the controller should match the rated voltage of the DC motor being controlled (within the 6V-60V range).
- Polarity: Always ensure correct polarity when connecting power and motor leads. Incorrect wiring can cause malfunction or damage.
- Environment: Operate the controller in a dry, well-ventilated area, away from flammable materials, moisture, and extreme temperatures.
- Professional Installation: If you are unsure about wiring or installation, seek assistance from a qualified electrician or technician.
6. Setup and Installation
Follow these steps for proper installation of the motor speed controller:
- Prepare Wiring: Ensure all power is disconnected before making any connections. Prepare appropriate gauge wires for your power supply and DC motor.
- Identify Terminals: The controller features screw terminals for connections. There are two sets of terminals: one for power input and one for motor output.
- Connect Power Input: Connect your DC 6V-60V power supply to the input terminals. The terminal labeled 'POWER +' is for the positive lead, and 'POWER -' is for the negative lead. Observe polarity carefully.
- Connect Motor Output: Connect your DC motor to the output terminals. The terminal labeled 'MOTOR +' is for the positive lead of the motor, and 'MOTOR -' is for the negative lead.
7. Operating Instructions
The Aideepen PWM DC Motor Speed Controller features a digital display, a rotary encoder knob, and a 'SET' button for operation.
7.1 Basic Operation
- Power On: Once wired correctly, apply DC power (6V-60V). The digital display will illuminate, showing the current speed percentage or a parameter.
- Start/Stop Motor: A short press of the rotary encoder knob (labeled RUN/STOP) will start or stop the connected DC motor.
- Adjust Speed: Rotate the rotary encoder knob clockwise to increase the motor speed and counter-clockwise to decrease it. The digital display will show the current speed as a percentage (0-100%).
7.2 Advanced Settings (Parameter Mode)
The controller allows for advanced configuration of various parameters:
- Enter Setting Mode: A long press of the rotary encoder knob (RUN/STOP) will enter the setting mode. The display will show a parameter code (e.g., P-1, P-2).
- Navigate Parameters: Rotate the knob to cycle through different parameter codes.
- Select Parameter: Short press the 'SET' button to select the currently displayed parameter for adjustment.
- Adjust Parameter Value: Rotate the knob to change the value of the selected parameter.
- Confirm Value: Short press the 'SET' button again to confirm the new value and move to the next parameter or exit the current parameter setting.
- Exit Setting Mode: Long press the rotary encoder knob again to exit the setting mode and return to normal operation.
Commonly Adjustable Parameters:
- Slow Start Time: Configures the time it takes for the motor to reach full speed from a stop.
- Slow Stop Time: Configures the time it takes for the motor to come to a complete stop from full speed.
- Upper Speed Limit: Sets the maximum achievable speed percentage.
- Lower Speed Limit: Sets the minimum operational speed percentage.
- Control Frequency: Adjusts the PWM frequency (1-100KHz) for compatibility with different motors.
8. Maintenance
To ensure the longevity and optimal performance of your Aideepen PWM DC Motor Speed Controller, follow these maintenance guidelines:
- Keep Clean: Regularly clean the exterior of the controller with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Avoid Moisture: Protect the device from water, humidity, and other liquids. Moisture can cause short circuits and damage internal components.
- Check Connections: Periodically inspect all wiring connections to ensure they are secure and free from corrosion. Loose connections can lead to intermittent operation or overheating.
- Ventilation: Ensure the controller has adequate ventilation to prevent overheating, especially during prolonged operation at high loads.
- Storage: When not in use for extended periods, store the controller in a cool, dry place.
9. Troubleshooting
If you encounter issues with your motor speed controller, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller does not power on / Display is off | No power input; Incorrect input voltage; Incorrect polarity; Loose connection. | Check power supply (6V-60V DC). Verify input voltage and ensure correct positive/negative polarity. Secure all power connections. |
| Motor does not run | Motor not connected; Incorrect motor polarity; Motor damaged; Controller in 'STOP' mode; Speed set to 0%. | Check motor connections and polarity. Ensure motor is functional. Short press RUN/STOP knob to start. Increase speed using the knob. |
| Motor runs at incorrect speed / Speed cannot be adjusted | Speed limits set too low/high; Potentiometer malfunction; Incorrect control frequency. | Enter setting mode (long press RUN/STOP) and check upper/lower speed limits. Verify control frequency (1-100KHz) is suitable for your motor. |
| Motor runs erratically / Overheats | Overload; Poor ventilation; Loose connections; Incompatible motor. | Reduce motor load. Ensure adequate ventilation around the controller. Check all wiring connections. Confirm motor is compatible with PWM control and voltage/current ratings. |
| Display shows error code | Internal fault; Overcurrent/Overvoltage protection triggered. | Disconnect power, wait a few minutes, then reconnect. If the error persists, contact customer support. |
