6. Operating Instructions
The controller allows for precise speed adjustment and configuration of various operational parameters.
Basic Operation:
- Power On: Once wired correctly, apply DC power. The digital display will illuminate.
- Start Motor: Press the RUN button to start the motor.
- Stop Motor: Press the STOP button to stop the motor.
- Adjust Speed: Use the UP (▲) and DOWN (▼) buttons to adjust the motor speed percentage.
Parameter Settings (MENU Mode):
Press the MENU button to enter the parameter setting mode. Use the UP (▲) and DOWN (▼) buttons to navigate between functions (F1-F5) and adjust their values. Press MENU again to save and exit, or wait for automatic exit after a few seconds of inactivity.
- Function 1 (F1): Slow Start Time Setting (000 - 100)
Adjusts the time (in seconds) for the motor to ramp up from 0% to the set speed. Range: 0-10 seconds. Default: 1 second. - Function 2 (F2): Slow Stop Time Setting (000 - 100)
Adjusts the time (in seconds) for the motor to ramp down from the set speed to 0%. Range: 0-10 seconds. Default: 1 second. - Function 3 (F3): Speed Lower Limit Setting (000 - 080)
Sets the minimum adjustable speed percentage. Range: 0-80%. Must be less than the maximum speed setting (F4). Default: 0%. - Function 4 (F4): Speed Upper Limit Setting (000 - 100)
Sets the maximum adjustable speed percentage. Range: 0-100%. Must be greater than the minimum speed setting (F3). Default: 100%. - Function 5 (F5): Acceleration and Deceleration Value Setting (001, 002, 005, 010, 015, 020, 025)
Determines the increment/decrement percentage when pressing the UP/DOWN buttons. Options: 1%, 2%, 5%, 10%, 15%, 20%, 25%.
7. Maintenance
The Yanmis DC Motor Controller is designed for durability and requires minimal maintenance.
- Cleaning: Keep the device clean and free from dust. Use a soft, dry cloth for cleaning. Do not use liquid cleaners or solvents.
- Inspection: Periodically check wiring connections for tightness and signs of wear or damage.
- Storage: If storing the controller for an extended period, ensure it is kept in a dry, cool environment.
8. Troubleshooting
If you encounter issues with your Yanmis DC Motor Controller, refer to the following common problems and solutions:
- No Power/Display Off:
Possible Cause: Incorrect power input, loose wiring, or power supply failure.
Solution: Verify DC 6-60V power supply connection and polarity. Check all wiring for secure connections. - Motor Not Responding:
Possible Cause: Incorrect motor wiring, motor fault, or controller settings.
Solution: Check motor connections and polarity. Ensure the motor is functional. Verify speed limit settings (F3, F4) are not set to 0% or conflicting. - Inconsistent Speed/Humming Noise:
Possible Cause: Motor incompatibility, power supply fluctuations, or environmental factors.
Solution: Ensure the motor is a compatible DC brush motor. Check power supply stability. While some humming can be normal for PWM controllers, excessive noise may indicate an issue with the motor or power supply. - Settings Not Saving:
Possible Cause: Not exiting MENU mode correctly.
Solution: After adjusting parameters, press the MENU button again to save and exit.
