Connection Steps:

1. Power Supply: Connect your DC power source (6-60V) to the VCC (positive) and GND (negative) terminals. Ensure correct polarity to prevent damage. The main board power supply circuit does not include a fuse; consider adding one externally for protection.
2. Motor Connection: Connect the three motor phase cables (U, V, W) from your brushless motor to the MA, MB, and MC terminals on the controller.
3. Hall Sensor Connection: Connect the Hall sensor wires from your motor to the corresponding Ha, Hb, Hc, +5V, and GND pins on the controller. This controller requires a motor with Hall sensors to function correctly.
4. Speed Control:
   • On-board Potentiometer: For manual speed adjustment, use the blue potentiometer on the board.
   • External Potentiometer/Analog Input (0-5V): If using an external potentiometer or a 0-5V analog signal (e.g., from a PLC), connect it to the 0-5V and GND terminals. The on-board potentiometer should be adjusted to its minimum setting when using an external control.
   • External PWM Signal Input: For PWM control, connect your PWM signal (amplitude 2.5-5V, frequency 50Hz-20KHz) to the 'P' pin and GND. The jumper cap on the board next to the speed pot needs to be removed when using external PWM.
5. Direction Control (DIR): Connect a control signal to the DIR terminal to change motor direction. This input is active high.
6. Brake/Stop (STOP): Connect a control signal to the STOP terminal for braking or stopping the motor. This input is active low.

Important Safety Note: Always test with small current and low voltage first after wiring. Avoid short circuits during operation, as this can damage the module. Ensure proper wire insulation, especially with high voltage.

Operating Instructions

Once properly wired, the RioRand motor speed controller allows for precise control of your brushless DC motor.

Speed Adjustment:

• Using On-board Potentiometer: Rotate the blue potentiometer on the board. Turning it clockwise increases speed, and counter-clockwise decreases speed.
• Using External Analog/PWM Input: If an external control signal is connected, the motor speed will be regulated by the voltage (0-5V) or PWM duty cycle provided to the respective input pins. Ensure the on-board potentiometer is set to minimum when using external control.

Direction Control:

Apply a high signal (e.g., 5V) to the DIR terminal to change the motor's rotation direction. Remove the signal or apply a low signal to revert to the original direction.

Braking/Stopping:

Apply a low signal (e.g., connect to GND) to the STOP terminal to stop the motor. Note that this function primarily cuts power to the motor and does not provide active braking or holding torque; the motor will stop due to friction.

Maintenance

The RioRand motor speed controller is designed for durability. To ensure its longevity and optimal performance:

• Keep the board clean and free from dust, moisture, and conductive debris.
• Ensure adequate ventilation around the controller, especially during high-load operation, to prevent overheating. The heatsink is located on the underside of the board.
• Regularly check all wiring connections for looseness or corrosion.
• Avoid exposing the module to extreme temperatures or sudden impacts.
