I have bought the controller and set it up in my scooter. Everything works (the modes, cruise control, etc.) and the scooter does drive faster, but I have a problem.

The screen does not work properly:

• the ready button is constantly on
• Speed shows 0 km permanently
• the mode is stuck in 1
• it doesnt show how much power the scooter is using

I have tried different hall cable connections, but the screen all doesnt show anything.

 

Do you guys know what the problem is? I connected the seller and he said that I burned the hall cable, but I installed it the proper way they gave it to me.

Hi Jens,

 

Basically what’s wrong is that the large cable that goes into your motorcontroller is just loose. If you reconnect it the connection should be better and no more errors.

 

Unfortunately when I drive now over bumpy roads the cable gets loose and I have to reconnect it, very annoying

Yes the location will still be updated even without the battery, it is however every 20minutes-ish.

It turned out that the motor was defect and I had to get it to be replaced, thanks for the help.

I have this too with my N1S, I believe its just the scooter being sensitive to wind.

I did notice that the aftermarket’s controller’s motor phase cables “connectors” were in a different order/sequence than the original NIU controller. Do you mean with that the cables could be connected wrongly, that I should connect the motor phase cables of the NIU in the same sequence of the original controller into the “new controller”? Currently, I connected all the colors of the NIU cables into the colors of the controller, so matching blue with blue, etc etc.

“Resistance of any pair of green/yellow/blue should match.”

Does that mean,  I can connect a green motor phase cable into a yellow connector as they have the same resistance, for example? Or would I risk short-circuiting the controller.

 

Thanks Eddy for your help

Hey Eddy,

Thanks for the reply and I believe there is something with either the Hall sensor or the Motor cable being loose. Because I saw an error of 120 before on my screen, even though now it doesn’t give any error code. Is there anything I can do myself to fix the Hall sensor or loose Motor cable or do I just have to bring it to the dealer?

I checked out my controller and I do not have the issues that its blinking.

After I went through the NIU manual, I found my problem, “The motor rotates and stops intermittently.”;.

As soon as I hit the pedal the motor gives a little gass, only to be abruptly be stopped.  I suspect that its because my hall cable sensor is broken, although I have no certainty that it is. What is the best way for me to go fix it though? Go to the dealer and tell them I have a broken motor hall sensor? Or is there anything I can do myself.

 

 

 

The motor rotates and stops intermittently.
1. Inspection of the battery pack voltage
Check the battery pack voltage.
Is the voltage at the critical under-voltage point? Is the battery in a bad condition?
Yes – the battery pack voltage is insufficient
The capacity of a single or multiple batteries is reduced
The battery connector is in a bad contact.
The charger failed
2. Inspection of the startup switch
Is the startup switch in a bad contact?
Yes – the startup switch failed or the wire is in a bad contact
No – go to step 3
3. Inspection of the Hall cable sensor
Is the Hall cable sensor in a bad contact?
Yes – the Hall cable sensor failed or the wire is in a bad contact
No – go to step 4
4. Inspection of the power supply lock
Is the power supply lock in a bad contact?
Yes – the power supply lock failed or the wire is in a bad contact
No – go to step 5
5. Controller inspection
Check the controller wire for bad contact
Yes – the controller wire is in a bad contact
No – the controller damaged

Even after doing what you said of connecting the 1 to 1 and leaving the 2’s unconnected, the NIU still has the constant”ready” and theres no “modes”. I suppose there’s something much worse wrong with my NIU since it doesnt even work with the original controller.

Any advice on what I can do?

I have to add that, although it can’t drive, it still turns on/off, switch modes, etc etc. There’s just a problem with accelerating.

I tried to unplug and plug all the cables again and have tried with the correct set up for the controller and the original controller, but it all doesn’t work. I hope someone can help me out.

After receiving my 17282 DC for the NIU N1S, I quickly tried to install it without any instructions on how to do so or whatever, I wasn’t patient enough to just wait until I got the instructions and then install it.

Now my NIU doesn’t drive anymore, although everything else works the screen, switching modes, ready button, etc etc. Does someone know what I should do? I really hope the dealer can fix it.
