New controller help.

[Michael Love]

I cannot get pedal assist to work but if I connect the green wire I can get the motor to work at different speeds with pas.

Can anyone help?

1. With green wire connected, I can increase speed without pedalling to max 15mph.

2. With green wire disconnected, I cannot get motor to work while pedalling. The 12 magnet pas sensor is working.

3. I do not have a speed sensor from the motor in the 6pin plug.

P01 = 3
P02 = 1
P03 = 36
P04 = 30
P05 = 1
P06 = 26.0
P07 = 50
P08 = 50
P09 = 0
P10 = 2
P11 = 1
P12 = 0
P13 = 12
P14 = 15
P15 = 28.0
P16 = 0
P17 = 0
P18 = 100
P19 = 0
P20 = 0

Thank you.

It's not a usual controller set up many use, d8veh did try one a similar one with 16p settings I think it was a brainpower one and had issues setting it up. How about a link to your controller ?

A few thoughts;

What do the the P settings represent without an agenda there is no way of knowing what they change . One of the settings will be for pas and magnet count, this looks like it might be P13 so 12 should be correct.

Although it say's 6mm between disc and sensor most often the gap needs to be 1 or 2mm max.

Disc and sensor orientation left or right may be wrong does pas work if you pedal backwards ?
Some pas only work one way and direction so there are four possible combos, if you have a bike stand put the bike up on it with pas sensor and disc removed, hold the pas sensor as it if was mounted on the correct side and pas the disc by it also rotate the disc so opposite face also passes it, repeat again as if the sensor was mounted on the opposite crank and try the disc again if one way works then you have to mount it that way around .

Another scenario if all fails I can think of is the pas needs to see a speed sensor , you could try fitting an independent one with spoke magnet, 5v & Gnd you could pick up from the pas, throttle or hall connector and then the coloured 3rd wire to the #2 white wire in hall connector as there is no separate speed sensor connector.

Thank you.

The three I have entered seem logical.

Hi,

The pas sensor is a 12magnet sensor. The led on the sensor does not flash if pedalling backwards.
It is 36V
I will adjust the low voltage cutoff to 30V.

Below the diagram in chinese writing is a link to a english word doc that tells what each setting does.

Thanks for all your help.

Sorry don't see that link...

Nor me...

You may need to test the speed sensor theory for it to work.

That's why mostly we suggest the more expensive but proven KT range as they do work.

Here are the settings.
4. 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).
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: Alterna

What is the brand of the PAS, the same as the controller?

My KT controller did not recognise the PAS signal sent from my GSM motor (similar to Bafang BBS0x PAS)

It was bought with the controller so I am not really sure.
Why would the pas signal be coming from the motor?
Thank you for all your replies.

The GSM and the Bafang BBS motors have internal PAS disks. My point was KT controllers have settings for KT (and other) PAS but not for the internal PAS of those mid drive motors - the signal is not recognised.

If you bought it with the controller it should be OK.

I have ordered a speed sensor but can I, with the aid of a diode, wire the pas sensor wire up to the speed sensor wire, or will the 12 pulses per pedal rotation make the controller think I am going real fast?
Thanks.

Nope. I fried a PAS hall sensor by pluging in the wrong wire. Be careful.

You don't need to anything fancy as a I have already mentioned.
Speed sensor has 3 wires Gnd/Black, 5v/ Red & signal/other colour. Connect the signal to the white hall connector wire & the other two pick up from any Gnd or 5v as they use a comon track on the board.
