SW900 displays wrong data

[Berko]

SW900 displays wrong figures as speed.

Only displays a speed figure (wrong) when applying throttle (when coasting at rolling with no throttle it shows speed =0).

Power meter on bottom of the screen is always at 0 watts.

P07 to 22, as that is the number of magnets I counted in the hub motor.

Any direction would be appreciated, thanks!

What kind of motor? Direct Drive or geared hub drive?

Try setting P 07 to 47

P07 Motor Speed Magnet Type
0-100
Set to 47 for direct drive motor, 100 for geared motors. Some brands may require 86 instead of 100 for their geared motors.

Update-
Tried all the combinations - from 1, 47, 100 and 86
No change..
Is there a way to "reset" the screen / ESC?

Hello,

I have the same problem!

did you manage to solve it?

I have a geared read hub motor 36v / 500w.

I'm wondering if the problem maybe the controller not the actual motors. Could be wrong, but trying to match displays with controllers can be very tricky as there are different communication protocols.

But the kit that i bought, the parts came all togheter. so i think is not a compatibility issue...

In your case it could be a failure of the display or controller. Have you contacted the seller for support.

But isnt display fault because i have another bike with the same display and i tried that display and the problem remains...
