4. Setup and Connections

Proper connection of the motor controller is crucial for its functionality and safety. Refer to the diagram below for connection points.

Figure 4.1: Connection Terminals

This image provides a detailed view of the connection terminals on the XY-BLDC board. On the right, the 'POWER' terminals (+ and -) are for DC input. Below them, the 'MOTOR' terminals (three pins) are for connecting the three-phase brushless motor. On the left, the 'J2' and 'J6' headers provide control inputs including GND, EN (Enable), AN (Analog input), PWM, and Hall sensor inputs (HA, HB, HC, +5V).

4.1 Power Connection

• Connect your 12-30V DC power supply to the 'POWER' terminals on the board. Ensure correct polarity: '+' for positive and '-' for negative.
• The board is designed for a maximum current of 7A. Ensure your power supply can provide sufficient current for your motor's requirements without exceeding this limit.

4.2 Motor Connection

• Connect the three phases of your brushless motor to the 'MOTOR' terminals (J1) on the board. The order of connection may affect the motor's rotation direction.
• This controller is specifically designed for three-phase brushless motors with a 120-degree electrical angle. Ensure your motor is compatible.

4.3 Control Signal Connections

The board supports various control inputs via the J2 and J6 headers:

• GND: Ground reference for control signals.
• EN (Enable): Used to enable or disable the motor output.
• AN (Analog Input): For 0-5V analog speed control.
• PWM: For PWM speed control.
• HA, HB, HC: Hall sensor inputs for motor commutation.
• +5V: On-board 5V supply, can be used for external potentiometers or sensors.

5. Operating Instructions

5.1 Speed Control via PWM

• Connect your external PWM signal source to the 'PWM' input pin.
• The recommended amplitude for the PWM signal is 5V.
• The recommended PWM frequency range is 1KHz to 10KHz.
• Varying the duty cycle of the PWM signal will adjust the motor speed.

5.2 Speed Control via Analog Input (0-5V)

• Connect an external analog voltage source (0-5V) to the 'AN' input pin.
• Alternatively, you can use an external potentiometer (resistance 10K-100KΩ) connected between the on-board 5V supply and GND, with the wiper connected to the 'AN' input, to adjust the speed.
• A higher input voltage corresponds to a higher motor speed.

5.3 Direction Control

The controller supports both positive and negative rotation. Specific pins or methods for direction control are typically indicated on the board or in advanced documentation. Refer to the pinout diagram (Figure 4.1) for relevant control pins.

5.4 Brake Function

The controller includes a brake function. Activation of this function will rapidly stop the motor. Consult the detailed pinout or advanced documentation for the specific pin responsible for activating the brake.

6. Troubleshooting

If you encounter issues with the XY-BLDC motor controller, consider the following:

• No Motor Movement:
  • Check power supply connections and ensure the voltage is within the 12-30V range.
  • Verify motor connections are secure and correctly phased.
  • Ensure the 'EN' (Enable) pin is activated (if applicable).
  • Confirm the motor is a 120-degree electrical angle brushless type.
• Erratic Motor Behavior:
  • Check Hall sensor connections (HA, HB, HC) for proper wiring.
  • Ensure control signals (PWM/Analog) are stable and within specified ranges.
• Overcurrent Protection Triggered:
  • Reduce motor load.
  • Ensure the motor's current draw does not exceed 7A.
  • Check for short circuits in the motor or wiring.

7. Maintenance

To ensure the longevity and optimal performance of your XY-BLDC motor controller:

• Keep the board clean and free from dust and debris. Use a soft, dry brush or compressed air for cleaning.
• Avoid exposing the board to moisture or extreme temperatures.
• Ensure adequate ventilation around the heat sink, especially during high-power operation, to prevent overheating.
• Regularly inspect connections for looseness or corrosion.

8. Safety Information

Please observe the following safety precautions:

• Always disconnect power before making or changing any connections to the board.
• Do not exceed the specified maximum voltage (30V) or current (7A) ratings.
• Ensure proper insulation for all wiring to prevent short circuits.
• Operate the controller in a well-ventilated area to prevent heat buildup.
• This product contains electronic components that can be sensitive to static discharge. Handle with care.
• Keep out of reach of children.
