BLDCM drive / Hall controller drive
Note:
1: this version of the manufacturer's software is the general version of small current and large torsion. Please explain before ordering the two-mold version. The current is normally set to 30A and generally set to 30A
2: the software of this board is 48V by default. When 60V/64V/72 is adopted, the 60V/64V/72V welding plate on the board is short-connected

Failure indicator definition description
| 1 long (bright) 1 short (off) | The first MOS tube (or corresponding drive) fails |
| 1 short 2 long | The second MOS tube (or corresponding drive) failed |
| 1 long 3 short | The third MOS tube (or corresponding drive) failed |
| 1 long 4 short | The fourth MOS tube (or corresponding drive) failed |
| 1 long 5 short | The fifth MOS tube (or corresponding drive) failed |
| 1 long 6 short | The sixth MOS tube (or corresponding drive) fails |
| 1 long 7 short | Phase line fault or drive part fault (the lamp is statically flashing normally, the motor is stuck by turning, the lamp is flashing for 7 times, and the power tube is normally driving on and off the bridge) |
| Uniform slow flashing (bright 1S off 1S) | No hall normal standby |
| Uniform slow flashing (on 0.5S off 0.5S) | Hall is on standby |
| Flash one time, pause for 1S | Brake failure: possible cause chip 2 pin low level |
| Flash 2 times. Pause for 1S | Over current fault: there is a large current in operation, short circuit of phase line, power tube damaged or drive circuit fault, or over current protection circuit configuration is not normal, chip 36,37 feet |
| Flash three times. Pause for 1S | Block - off: block - off with heavy load or hall fault simulation |
| Flash 4 times. Pause 1S | Undervoltage: battery voltage is too low or voltage detection circuit fault |
| Flash five times. Pause for 1S | Operational failure: chip damage or operational amplifier configuration circuit failure |
| Flash 6 times. Pause 1S | Hall of failure |
| Flash 7 times. Pause 1S | Missing phase: please check whether the motor wire is well connected and the corresponding drive part is normal |
One-key repair function instructions:
1: XH function brake, manual and automatic cruise when under pressure fault, effective to ground
2: the braking power is broken during cycling. At this point, the XH port is grounded, and the car will continue to drive at 20% speed
3: under riding pressure, the XH port will be grounded, the car will continue to drive at 20% speed, and the port XH will be lifted
This key repair function is designed for the vehicle to break down in the middle of the road, to avoid the implementation or implementation of difficulties, the corresponding emergency treatment, so as to reach the repair shop maintenance. This function can reflect the human side more, reduce the awkward situation that the car broke down during the journey
