How to set the tachometer: 1. Select "1" for mode 2. Set the frequency division value to the motor "pole pair number" 3. If the pole pair number is 2, set the frequency division value to 6 (2*3=6) Special instructions for external signal input: 1. When external PWM signal input is connected from the PG2 ports of the mainboard (the built-in potentiometer on the board is adjusted to the minimum, and the short interface on the board is short-circuited for wiring as shown in the figure above), the amplitude is 2.5-5V, and the frequency is 50HZ-20KHZ 2. When external analog 0-5V input is connected, input from the 2 wiring terminals of the mainboard (the built-in potentiometer on the board is adjusted to the minimum, and the wiring is shown in the dotted line in the figure above) 3. When the external potentiometer is used for speed adjustment, connect the corresponding 3 wiring terminals of the mainboard (the potentiometer on the board is adjusted to the minimum, and the wiring is shown in the potentiometer diagram in the figure above) 4. Forward, reverse and stop are connected to ground (0 potential) through a switch, and low level is effective, and the external MCU can also give a low level signal. The brake is connected through a switch connected to 5V high level valid. The front row of wiring terminals are all weak current signals directly input to the MCU main control. They must not touch or come into contact with high voltage and strong current. 1. MAMBMC phase line output connects to the motor; 2. 5VGND The motherboard comes with a 5V power supply (the external power supply current does not exceed 50MA) 3. VCCGND main power supply (external DC power supply) 4. SC speed pulse signal output (only the interface is reserved, no technical support) 5. DIR direction control forward and reverse control interface (low level is valid and can be connected to an external switch on the ground) 6. STOP stop control interface (low level is valid and can be connected to an external switch on the ground) 7. BRAKE brake control brake control interface (high level is valid and can be connected to an external 5V switch) 8. Speed ​​control speed control signal input (the integrated potentiometer on the board can also be connected to an external 0-5V analog PWM dual signal input for speed control) 9. HaHbHc+5VGND Hall signal power supply input interface. Generally, motors with Hall have corresponding 5 wires ; Note: 1. Since the forward and reverse rotation is a hard commutation without delay and the brake will have a great impact, these two functions cannot be operated when running at high voltage and full speed. Forced operation may damage the power tube and chip. The speed control throttle must be reduced to below 50%. 2. The maximum voltage (60V) and maximum power (350W) marked on this module are limit parameters under specific conditions. In actual application, a margin should be left for use

Note: This driver is a DC three-phase brushless control board. The motor needs Hall to work properly. Only applicable to electrical angles of 120 degrees.

If you are not clear about the definition of the motor phase line and the Hall line, and it cannot work properly after being connected, you can blindly connect according to the following method and then slowly change the Hall line sequence. First, connect the three phase lines of the motor to the phase line interface of the driver board at will. There are five Hall lines on the motor. Three Hall signal lines are connected to the three Hall signal ports on the driver board at will. The other two Hall power supply lines must be connected correctly (the motherboard will provide 5V power supply. One of the Hall lead wires we send is red 5V and the other is black ground wire. You must find a way to connect it to the motor Hall power supply line. Remember!!!) After checking that everything is connected correctly, power on for low voltage (7-12V) and low current (1-3A) power-on debugging (if conditions permit, use constant DC power supply or low power power supply plus current limiting resistor, etc.), turn on the potentiometer on the board to adjust the speed throttle to about 20%. If the motor does not rotate or there are other abnormal phenomena, immediately turn off the power, and then change the order of the three phase lines of the motor (because the phase line interface on our driver board is a terminal, it is more convenient to connect and remove the wires, so I use the motor phase line to change the line sequence. If the motor phase line is fixed, the principle of changing the three Hall signal line sequence is the same. It depends on personal preference). Until it can rotate smoothly after power is turned on, it means that the wiring is correct. There are 6 different combinations of line sequence change. I will list them below: If the order of the currently connected phase lines is defined as ABC, it can be changed to ACB BAC BCA CAB CBA. Each time these combinations are changed, the machine is tested once. Only 1 of these 6 combinations is correct.

When the wiring is incorrect and the operation is abnormal, do not test the machine with high current and high voltage, otherwise there is a risk of damaging the driver board. After the three motor phase lines are swapped, if the line sequence is correct, the motor will run as smooth as silk after power on, start smoothly at low speed, and have high torque; if the three motor phase lines are not connected in the right order, generally there are 1. After power on, the motor cannot start normally and has no response, or it only shakes when starting and cannot rotate normally. 2. There is a slight shake, it is difficult to start, it cannot turn, and it makes a slight sound. Sometimes it needs to be manually turned to turn. 3. The motor can turn in one direction, but not in the other direction, and there is some slight sound. 4. The motor starts with a large shake and is weak, there is a sound, and the current is obviously too large. The power tube is obviously heated and serious

1. There is no fuse in the power supply circuit on the main board, and it is recommended to add it by itself. The positive and negative electrodes of the power supply will be connected to the reverse part of the board
The chip is permanently damaged (even a few seconds at high current) 2. During normal operation, the output end of the motor has sampling overcurrent protection. Since the power current of the module is very large, please do not
Artificial short circuit when the module is not working properly Each, once the short circuit has the possibility of burning the line and bursting, the first wiring test
Please test the machine with small current and low voltage. After ok, turn on large current and high voltage. Because it is a bare board module for sale
Pay attention to the insulation of the wiring head, and it is strictly forbidden for strong voltage to touch the parts on the board. 3. Do not connect motors that obviously do not match the voltage, current and power of the drive module or are far apart, avoid Inexplicable "nonsensical" damage
