About Product ：
1.MA MB MC phase line output connection motor
2. 5V GND motherboard comes with 5V power supply (current does not exceed 50MA)
3.VCC GND motor main power supply (external DC power supply)
4.SC speed pulse signal output
5 positive and negative reversing control interface (also can be connected to the external switch)
6.VR speed control signal input (onboard with potentiometer speed control can also be connected to 0-5V analog simulation PWM duty cycle to support dual signal input speed regulation)
7.Ha Hb Hc +5V GND Hall signal Power input, generally with Hall's motor has five corresponding lines
Full patch process Stable performance with positive/reverse function
Tips:
After receiving the goods, there are generally 5 Hall wiring lines on the brushless motor. Two of them are the Hall power supply lines. The three Hall signal lines must be distinguished. Especially, the power supply lines must not be mistaken. The sequence on the board must match the sequence of the three phase lines on the motor driver board to work properly. If you do not know the definition of the Hall wire, you can debug the low voltage and current at the first power on. Change the order of the Hall line until normal operation, do not use large current, high voltage debugging, if the Hall line is not connected in sequence, the high voltage and high current test machine, there is the risk of damage to the MOS tube, if the three Hall signal lines The motor is running smoothly and smoothly. The low-speed start is stable and the torque is large. If the three Hall signal lines are not connected, the following characteristics are available: 1 The motor cannot be started normally or the start-up is difficult (sometimes it is necessary to manually turn the motor to start) 2 The motor starts to shake with no power.

Precautions:
1. The power supply circuit on the main board has no fuse, and the built-in self-addition will cause permanent damage to the chip on the board (even 2 seconds is not allowed).
2. During normal operation, there is sampling overcurrent protection at the motor output. Since the module power and current are very large, please do not short circuit when the module is not working normally. Once the short circuit has the possibility of burning the line, the first wiring test machine Please use small current and low voltage test, after ok, then pass high current and high voltage, because it is bare board module for sale, pay attention to the wiring line insulation, strong voltage is not allowed to touch the board parts.
3. Do not connect the motor that is obviously inconsistent with the voltage and current of the drive module or is far away from the motor to avoid inexplicable damage.
