Can't believe I missed it, P19 simply removes PAS level 0. That way you can not (temporarily) disable PAS by selecting level 0. I have updated the description for P19 in the user manual and also made a few other changes. If anyone wants me to add or change something, please let me know. You can...

Well, that's what P10 does: P10: Drive mode: 0 = PAS (1:1) enabled (throttle is disabled) 1 = Throttle enabled (PAS is disabled) 2 = PAS and throttle are both enabled. It could be a function that's not even available on this controller. P04 (Standby timer) doesn't seem to work either.

I first thought it would change the default PAS level on power up but I haven't noticed any change when messing with P19. There is another setting that is already used for disabling/enabling PAS and throttle, P10 so this must be something else entirely but no idea what it is. I did change the...

Thanks for that, I did some research on P07 and updated the user manual. I also added the zero start discription but I am unsure of the minimum speed required. Any idea what P19 is used for? Please download the user manual again to see the changes. I have also edited the famous connector pic of...

I have taken the liberty to clean up the S866 user manual that was floating on the web and created an unofficial/fan-version of it. I have added and removed some things that hopefully improve the readability and reduce the setup time. This manual is by no means perfect, there still are some...

Just wild guessing here, are the two green wires connected to eachother? Have you set the right number of motor magnets(and reduction if needed) and the right wheel diameter? Oh and are you sure you connected the PAS to the PAS input and not to the throttle input?

Yes, you are right, it's a digital signal. But what I'm saying is when I rotate the wheel in reverse I will only measure voltage between Vs and Q not between Gnd and Q. Now that I am home again I ran another test and found I can actually see the signals when the motor is engaged (I used the self...

I think you misunderstood. What I meant was in order to test the output of the hall sensors when the wheel is moving in driving direction(forward) you will not be able to get a signal from the hall sensors when moving the wheel by hand. It will only work when the motor is engaged (or also when...

Aaah, I think I have the solution. Contacted someone who has a video on youtube of replacing hall sensors. He says geared motors only output a signal in forward direction when the motor engages. So I'll just have to test the sensors with the motor running. The display now shows E07 so I think...

Well, I don't know what to tell you, I used two multimeters and tested the sensors three ways: when they were connected to the original controller, when they were connected to the brainpower controller and when only + and - of the controller were connected and the outputs of the sensors were not...

Okay, ran some more tests on the hall sensors in the motor. And this is what I've found: The sensors only work when the motor is rotated backwards/in reverse. Also the hall sensors output is - (connected to ground) instead of +. So I only get a signal if I measure between the Vs (5v+ input) and...

Now that I slept on it, I think the factory installed hall sensors in the motor could simply be the wrong type. I can't imagine the magnets in the motor are in the wrong orientation but then you never can tell with these fast production lines. I wonder if that one hall sensor Sino replaced now...

So why would the hall sensors in a wheel hub only work when the wheel rotates backwards? Does that mean the hall sensors weren't working when the wheel left the factory? Or is there another explanation for it? What I find even more strange is that the other Fiido D2 that I have also gives me the...

Not the PAS, the hall sensors in the wheel seem to only work when I rotate the wheel backwards.

I got my S866 and brainpower controller today. Before swapping the controllers I tested the sensors first. Figured out I had to "re-pin" the PAS connector for it to work with the stock 6 magnet PAS. Also measured the three hall sensors in the wheel hub and this is where things get interesting...

The KT controllers are definitely better, I saw some scope pics showing they are half sine controllers. But to be fair, they differ quite a bit in price, you can get a S866 set for as low as 27 Euros and if used on a cheap, foldable bicycle like the D2 I think they are great value. If you are...

That's exactly what I mean, these cheap controllers just count signals. The PAS sensitivity only dictates after how many PAS signals the motor starts.

As far as I know these controllers expect a "minimum" number of signals from the PAS. When the number of signals is below the minimum the motor will cut out.

Aaah, maybe that is what the negative feedback on the other controller was about. So the 1 to 5 levels DO work, it's just setting P12 that doesn't seem to make a difference. Thanks for all the info, I will be sure to carefully check my connections. I own 3 Fiido D2 bicycles, hoping to update...

Thanks again Emanuele. One more (silly) question. I noticed the description of the cable layout is a bit vague when it comes to the connectors for PAS sensor and throttle. One connector is marked "speed throttle" which anyone can imagine will probably be the throttle connector. And the other is...
