5. Operating Instructions
This section outlines how to operate the BANRIA Stepper Motor Driver Controller and adjust its parameters.
5.1 Basic Operation
- Running Interface:
- Press the CW button for clockwise/forward rotation.
- Press the CCW button for counter-clockwise/reverse rotation.
- Press the RUN/STOP button to start or stop motor operation.
- Rotate the potentiometer to change the rotation speed.
- Entering Menu Settings: From the running interface, press and hold the potentiometer for more than 3 seconds to enter the menu settings.
5.2 Parameter Setting Methods
The controller allows for detailed parameter adjustments through its menu system.

- In Menu Settings Interface:
- Rotate the potentiometer to cycle through parameters F-01 to F-14.
- Press and hold the potentiometer for more than 3 seconds to save the current parameter and exit the Parameter Set Mode.
- Modifying Parameter Values:
- Method 1: Directly rotate the potentiometer to change the value.
- Method 2: Short press the potentiometer to select a digit (the selected digit will blink). Rotate the potentiometer to change the value of the blinking digit. Repeat for other digits.
- Short press the RUN/STOP button to exit parameter settings and return to the main menu number adjustment interface.
6. Maintenance
To ensure the longevity and optimal performance of your BANRIA Stepper Motor Driver Controller, follow these general maintenance guidelines:
- Cleaning: Keep the device clean and free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using liquid cleaners or solvents.
- Environment: Operate the controller within the specified temperature and humidity ranges. Avoid exposure to extreme temperatures, moisture, or corrosive environments.
- Connections: Periodically check all wiring connections to ensure they are secure and free from corrosion. Loose connections can lead to intermittent operation or damage.
- Ventilation: Ensure adequate airflow around the controller, especially around the heatsink, to prevent overheating. Do not obstruct ventilation openings.
7. Troubleshooting
This section provides solutions to common issues you might encounter with the stepper motor driver controller.
- Motor Not Moving:
- Check power supply: Ensure the DC input voltage is within 10V-30V and correctly connected.
- Verify motor wiring: Confirm that the stepper motor wires (A+, A-, B+, B-) are correctly connected to the controller.
- Check RUN/STOP button: Ensure the motor is not in a stopped state.
- Review parameter settings: Verify that speed and mode settings are appropriate for the motor.
- Motor Runs Erratic or Vibrates:
- Incorrect micro-step setting: Adjust the micro-step resolution via DIP switches to match your application requirements.
- Current setting: Ensure the output current setting is appropriate for your motor. Too low or too high can cause issues.
- Loose connections: Check all motor and power connections for tightness.
- Motor type: Confirm the motor is a unipolar two-phase, 4-wire stepper motor compatible with the controller.
- LCD Display Not Working:
- Check power supply: Ensure the controller is receiving power.
- Contact support: If power is confirmed and the display remains blank, there may be an internal fault.
- Overheating:
- Check current setting: Ensure the output current is not set excessively high for the motor.
- Verify ventilation: Ensure the heatsink is not obstructed and there is adequate airflow.
- Holding current: Consider enabling the 1/2iRun holding current setting via DIP switch SW7 to reduce heat when the motor is idle.
