" Interface Description: 1.UVW phase line output connected to motor 2.5V GND The motherboard comes with 5V (current does not exceed 100MA) 3.VCC GND main power supply (external DC power supply) 4.SC speed pulse signal output (only leave the interface without technical support) 5.DIR forward and reverse control (can be connected externally) 6.BRAKE brake control (can be connected externally) 7.0-5V PWM speed control signal dual input (the onboard potentiometer can also be used to adjust the speed of the external 0-5V analog PWM duty cycle signal dual input speed control) Main board specifications: Product name:380W Brushless Hall Motor Controller Working voltage:5-50V Drive current:rated 16A plus air cooling 30A Maximum power:380W Overcurrent protection:Yes Stall protection:yes (after stalling,the current will automatically drop and run in isolation) Over-temperature protection:yes (half the over-temperature power) Precautions: 1.The reverse connection of the power supply on the motherboard will cause permanent damage to some chips on the board (not even 2 seconds) 2.There is sampling overcurrent protection at the output of the motor during normal operation. Since the power current of the module is very large, please do not artificially short-circuit when the module is not working normally. Once the short circuit may burn the line and burst the tube, the first wiring test Please test with low current and low voltage. After ok, then pass high current and high voltage. Since it is a bare board module, pay attention to the insulation of the wiring terminal. It is strictly forbidden to touch the parts on the board with strong voltage. 3.Don't connect the motor that is obviously inconsistent with the voltage, current and power of the drive module or far away from each other, to avoid inexplicable ""no point"" damage.
