Common errors:
- E30 seemed to be a connector that wasn’t making a good connection
- E10 seemed to be a setting in the LCD – namely this one that controls the communication protocol, I put P20 to 0 and it seemed to work
P20:0: Protocol No. 2 1: 5S Protocol 2: Alternate 3: Alternate
Below are the list of all the P codes and fault codes from the manual.
Display Settings:
- P01: backlight brightness, level 1 is the darkest, level 3 is the brightest;
- P02: mileage unit, 0: KM; 1: MILE;
- P03: Voltage level: 24V, 36V, 48V, 60V, 64V Default 36V;
- P04: Sleep time: 0, no sleep; other numbers are sleep time, range: 1-60; unit minutes;
- P05: Power assist position: 0, 3 file mode: 1, 5 file mode:
- P06: Wheel diameter: unit, inch; accuracy: 0.1; This parameter is related to the display speed of the meter and needs to be entered correctly.
- P07: Number of speed magnets: Range: 1-100; This parameter is related to the display speed of the meter and needs to be entered correctly. If it is a normal hub motor, directly input the number of magnetic steel; If it is a high speed motor, it is also necessary to calculate the reduction ratio, input data = number of magnets × reduction ratio; For example: motor magnet steel number 20, reduction ratio 4.3: input data: 86=20×4.3
- P08: Speed limit: the range is 0-100km/h, 100 means unlimited speed. The input data here indicates the maximum running speed of the vehicle: for example, input 25, indicating that the maximum running speed of the vehicle does not exceed 25km/h; the driving speed is maintained at the set value. Error: ±1km/h; (both assist and speed limit) Note: The value here is based on kilometers. When the unit setting is converted from kilometer to mile, the speed value of the display interface will be automatically converted to the correct mileage value, but the speed limit value data set at this menu under the mile interface. No conversion, inconsistent with the actual display mile speed limit value;
Note: The P09-P15 menu is only valid in the communication state.
- P09: zero start, non-zero start setting, 0: zero start; 1: non-zero start;
- P10: Drive mode setting 0 : Power drive (the booster position determines how much power is output, and the switch is invalid). 5 1 : Electric drive (driven by the rotary handle, the power assist position is invalid at this time). 2 : Power assist drive and electric drive coexist simultaneously
- P11: Boost sensitivity setting Range: 1-24;
- P12: Boost start strength setting Range: 0-5;
- P13: Power magnetic steel disc type setting 5,8,12 magnetic steel three types
- P14: Controller current limit value setting Default 12A Range: 1-20A
- P15: Controller undervoltage value
- P16: ODO clear setting Long press the up button for 5 seconds ODO clear
- P17:0: cruise is not enabled, 1: cruise is enabled; auto cruise is optional (only valid for protocol 2)
- P18: Display speed ratio adjustment range: 50%~150%,
- P19: 0 gear enable bit, 0: 0 gear, 1: 0 gear
- P20:0: Protocol No. 2 1: 5S Protocol 2: Alternate 3: Alternate
