Feature:1. Humanized design, the interface uses a terminal, a standard heat sink, and an integrated speed potentiometer on the board2. Full chip technology, stable performance, with forward and reverse, brake function, motor speed controller adopts Hall brushless controller3. Wide voltage 660V high power 400W DC threephase brushless with Hall controller4. Support PLC 05V analog control, support PWM to 05V control, can be used when power is on, saving time and effort5. There are three relatively thick phase wires on the machine, and there are also three phase wire interfaces on the drive board, which are marked MA, MB, MC, etc.Specification:Item Type: Motor ControllerMaterial: PCBPurpose: Motor ControllerMaximum Current: Rated 16A Maximum 20AMaximum Power: 400WOvercurrent Protection: Yes.Package List:1 x Motor Controller1 x Terminal LineNote:1. This drive is a DC threephase brushless control board, which requires the motor to have a Hall to work normally2. This drive is only suitable for DC brushless and Hall motors with an electrical angle of 1203. When the PWM signal is input from the 2 ports of the motherboard P G (the builtin potentiometer on the board is adjusted to the minimum, and the short interface on the board is shorted at the same time, the wiring is shown in the figure above), the amplitude is 2.55V, and the frequency is 50HZ20KHZ.4. When the external analog 05V input, input from the 2 terminal ports of the main board (the potentiometer on the board is adjusted to the minimum, the wiring is shown by the dotted line in the figure above)5. When the external potentiometer is used to adjust the speed, connect it to the 3 terminal ports of the main board (the potentiometer on the board is adjusted to the minimum, and the wiring is indicated by the potentiometer on the picture)6. The forward and reverse rotation and stop are grounded through a switch (0 potential). The low level is valid, and the external MCU can also give a low level signal. The brake is connected to a 5V highlevel effective through a switch. The front row of wiring terminals are all weak current signals directly input to the MCU main control, and cannot be touched or touched with high voltage and strong current.7. When the PWM signal is input from the 2 ports of the motherboard PG (the builtin potentiometer on the board is adjusted to the minimum, and the short interface on the board is shortcircuited at the same time as shown in the figure above), the amplitude is 2.55V, and the frequency is 50HZ20KHZ.8. When the external analog 05V input, input from the 2 terminal ports of the main board (the potentiometer on the board is adjusted to the minimum, the wiring is shown by the dotted line in the figure above)
