LCD DISPLAY 866 + Brainpower Controller no performance / Failure E07

[Michi]

Hello,
my bike has a 36V motor whithout hallsensors. I have a 5 magnet PAs sensor.
I got the electric motor running. All functions are ok, but the whole thing only runs in test mode when the wheels are free (without load). In driving mode the motor does not work. Immediately after switching on the control unit, the display shows the message E07 for motor failure. The engine runs but has no power. The motor has no Hall sensors. Is it possible that the control only works with motors with Hall sensors? What do I have to change when operating without Hall sensors? How do I get rid of the E07 message?
Thanks for your answers
Michi

Has your controller got the self-learning wires, sometimes called itelligent idrntification or something like that? They're normally two single green wires.
If so, did you do the self-learning procedure.

 

[Michi]

Yes, i tried this several times. The result is that the wheel is turning backwards or forwards. The error is still E07.

Are the green wires still connected?
Is there a 9-pin motor connector near the motor?

 

[Michi]

No, the green wires are disconnected. There is no 9-pin connector near the motor. It is a front motor whithout hall sensors. It has only the 3 phase power connector. It is a Promovec Motor 50080- 2
from a Bergamont Vagonda N8 Wave Pedelec from 2011.

Hi, did you ever get it working? I have same problem

According to the review at the bottom of the 1st page here https://www.aliexpress.com/item/1005002264800374.html
the controller can run without hall sensors in the motor. If your controller is identical to the one being sold there, there may be hope, but I can't see how you would get rid of the error message (from the displayed instructions). Or maybe the reviewer was reviewing a different model. I ordered one of these and waiting for it.

Ignore E 07. Try swapping the phase wires.

Just quick question think I ordered the wrong controller,you see it's a brainpower 36/48v 250w 13a controller problem is it has no LCD connection, anyway to fix it please anyone

 

[manman94]

Also there is a orange and yellow connection that's in a loop any idea what that's for

Orange and yellow is the on-switch. With it bridged, the controller will be switched on all the time a live battery is connected to the main red and black wires. If you don't want that, you put a switch on that connector instead of the bridge. The current on those wires is very low (about 100mA) so you can use any switch.

There is no way to connect an LCD to that controller. You hid the important wires in your photo, so I can't help beyond that.

So guys is there a fix for this problem? Is the hall sensors the failure?

What problem do you have? Please give exact details of what it is and what you have if you seek a solution.

So I try to explain. I have a s866 display with sm connectors it's a very plain one. I have a 250 watt front mounted motor. And I have sensor with 12 magnet in the middle. The issue is that I can turn the wheel with the 2 green wires connected. But without the 2 green wires connected I have a E07 malfunction code. How or what can I do to let this work properly?

Which motor is it? Is it with or without hall sensors?

Its a motor with hall sensors. I dont know with motor it is, and i am not at home.

Error 07 normally comes when there is a motor connection issue or hall sensor fault. If it only works during self-learning and low power, then one of the connections isn't in properly. Make sure that the motor's 9-pin connector is in all the way to the line, not just in tight, and check that the bullet connectors are all the way in and tight.

If none of that fixes it, you should get an ebike tester so that you can see what the controller sees. If you get one and need to know how it works, ask again when you have it.
