5. Setup agus Uèir

Carefully follow the wiring diagram to ensure correct connections. Incorrect wiring can damage the controller or motor.

Wiring Diagram Overview:

Ceumannan ceangail:

1. Power Supply (VCC, GND): Connect your DC power supply (6-60V) to the VCC (positive) and GND (negative) terminals on the controller. Ensure the polarity is correct.
2. Motor Phase Lines (MA, MB, MC): Connect the three phase wires from your brushless motor to the MA, MB, and MC terminals on the controller. The order of these connections may affect motor rotation direction.
3. Hall Sensor Connections (Ha, Hb, Hc, +5V, GND):
   • Connect the +5V and GND wires from the Hall sensor harness to the corresponding +5V and GND pins on the controller's Hall sensor interface.
   • Connect the Ha, Hb, Hc signal wires from the Hall sensor harness to the Ha, Hb, Hc pins on the controller. Ensure these correspond correctly to the motor's Hall sensor outputs.
   • Thoir an aire: This controller requires a Hall sensor motor to function. If your motor does not have Hall sensors, this controller will not operate.
4. Speed Control Input:
   • External Potentiometer (0-5V Analog): Connect the potentiometer's output to the 'Control input' terminal and its ground to the 'Ground GND' terminal. The controller provides a 5V supply for the potentiometer.
   • External PLC 0-5V Analog Signal: Connect the PLC output to the 'Control input' terminal and its ground to the 'Ground GND' terminal.
   • External PWM Signal: Connect the PWM signal to the 'Control input' terminal and its ground to the 'Ground GND' terminal. The PWM signal should have an amplitude of 2.5-5V and a frequency between 1K-20KHz.
   • Thoir an aire: If using an external speed control signal, the jumper cap on the board for the on-board potentiometer must be removed.
5. Direction Control (DIR): Connect a switch or control signal to the 'DIR' terminal. Shorting 'DIR' to ground will typically reverse the motor direction.
6. Stop Control (STOP): Connect a switch or control signal to the 'STOP' terminal. Shorting 'STOP' to ground will stop the motor.
7. Brake Control (BRAKE): Connect a switch or control signal to the 'BRAKE' terminal. Shorting 'BRAKE' to ground will activate the motor brake function.
8. SC Speed Pulse Signal Output: This terminal provides a speed pulse signal output, which can be used for external speed monitoring.

6. Stiùireadh Obrachaidh

Once all connections are securely made and verified, power on the controller. The motor should be ready for operation based on your control inputs.

Gnìomhan:

• Smachd air astar: Adjust the connected potentiometer or provide the appropriate 0-5V analog/PWM signal to the 'Control input' to vary the motor speed.
• Direction Control (DIR): Toggle the 'DIR' input (e.g., connect to ground) to switch between forward and reverse rotation.
• Stop Function (STOP): Activate the 'STOP' input (e.g., connect to ground) to bring the motor to a halt.
• Brake Function (BRAKE): Activate the 'BRAKE' input (e.g., connect to ground) to engage the motor's braking mechanism.
• Dìon thar-ghnèitheach: The controller is equipped with overcurrent protection to safeguard against excessive current draw.

7. Cumail suas

• Cùm an rianadair glan agus saor bho dhuslach is sprùilleach. Cleachd clò bog, tioram airson a ghlanadh.
• Regularly inspect all wiring connections for looseness or damage. Tighten any loose connections.
• Ensure adequate airflow around the heatsink to maintain optimal operating temperature.
• Avoid exposing the controller to extreme temperatures or humidity.

8. A ’dèanamh trioblaid

• Motor not spinning:
  • Thoir sùil air ceanglaichean solar cumhachd agus an tomhas-lìonaidhtage.
  • Verify all motor phase (MA, MB, MC) and Hall sensor (Ha, Hb, Hc, +5V, GND) connections are correct and secure.
  • Ensure the motor is a 120-degree electric angle DC brushless Hall motor.
  • Confirm the speed control input is active and providing a valid signal (0-5V or PWM).
• Motor spins slowly or inconsistently:
  • Check the quality and stability of the speed control input signal.
  • Inspect Hall sensor connections for intermittent contact.
  • Dèan cinnteach nach eil cus luchd air a’ motair.
• Motor does not stop or brake properly:
  • Verify the 'STOP' or 'BRAKE' control input connections are functioning correctly (e.g., shorting to ground).
  • If using a Hall throttle, ensure its minimum output voltage allows the motor to fully stop. Some Hall throttles may require external modification (e.g., adding diodes) to achieve a true 0V equivalent at idle.
• Controller overheating:
  • Ensure adequate ventilation around the heatsink.
  • Check if the motor is drawing excessive current, potentially indicating an overload or fault.
