Initial Set-up

Unread post by hdserv » Tue Nov 26, 2019 2:01 pm

My setup, QS Motor 205 50H V3 Motor 3000W, F24-120 Controller with the latest Blue Tooth Module, 24S 20Ahr Lipo Pack. I believe that I've wired everything correctly. When running the app, I'm able to connect to the controller, battery voltage displayed on the dashboard is accurate. I have the throttle plugged into the blue tooth module and when I twist the throttle I can watch the throttle position change up and down on the dashboard display. The hub motor however doesn't run at all? I'm hoping it's simply my error in programming.

Any Help?
TY, Daniel

QS Motor 205 50H V3 Motor 3000W, F24-120 Controller with the new Blue Tooth Module 2.0, 24S 20Ahr Lipo Pack, updated firmware today.

I got lucky. I kept trying anything and everything clearing cache and data within the PV app, then re-entering my program settings. Then I happened to find one the the motor hall sensor leads dislocated. I relocated that and Bam my bike sprung to life!

I've a got WOT issue though, and I had not experienced this when testing while my bike was up on the stand. It was only when I attempted my first test ride that I got WOT twice :shock: Luckily I've got good brakes and shut off the key switch.
I've got the throttle plugged into the new blue tooth module 2.0 and my bike's back up on the stand. There is an alternate plug for the throttle, maybe that will solve it?

Any thoughts?
Thanks,

Daniel

Please plug in the throttle directly to the controller (bypassing the Bluetooth). That will fix it.

My WOT issue is now solved after relocating the throttle wiring and plugging directly to the controller. Thank Very Much!

Now it seems that my programming efforts are having little to no effect on my bike's performance. After programming, Start-up is and can be very smooth.
Regen seems to be working properly when I have it turned on.

It makes no difference however what position My 3 speed switch is in, what % torque/rpm setting I'm testing, At least for now I'm unable to go faster than about 25mph.

Any Help?

Please attach a screenshot of your programmed values (from the Programming screen).
Also, please explain how you connected the three-way switch.

I checked and double checked the wiring of my 3 speed switch.

It appears my wiring is correct (Though, there are splices and may be suspect).
Wires from switch, green low speed, black ground, red over-speed.
Wires from controller, grey low speed, black ground, blue over speed.

I checked again today the switching action with a meter and yes I've got the 3 speed switch wired correctly. Still, I'm unable observe any difference when switching between speeds. :?

Also I'm having an intermittent challenge connecting and programming via the bluetooth 2.0. Sometimes it connects very easily other times I can't connect no matter what I try. It always recognizes the bluetooth module however and still won't sometimes connect?? :cry:

For the first time I rode my bike about 15 miles today. Hot off the charger, 100.8V my bike flys, 50+mph. The bike performs admirably till about 96-97V when I start losing power and then slows, slows and then dies altogether below 95V. Good thing I have pedals as I needed them to get me back that last mile.

What am I doing wrong?
Any Help?

Update:

I recharged the battery and then was able to realize full power again (50+ mph). After reconnecting and changing the program setting I lowered the low voltage cutoff and found I had full power all the while riding another 10 miles. I wanted to find out at what voltage I might begin to lose power. I was really having more fun than on any of my other ebikes.

Regrettably, I decided to make one last run, and in my exuberance I prolly burned up the motor (even though the motor wasn't what I consider extremely hot). On acceleration The bike stalled out and made a really bad grinding noise and then nothing. I can't really pedal the bike as the rear wheel has some measure of rolling resistance that wasn't there prior.The battery got to about 39C

It's not the controller I suspect as I'm able to connect and make program changes.

It'll be at least a month before we get home again and I can get the bike back up on the stand.
Tomorrow I'l check to see if the motor windings are open. :twisted:

Yes, it's starts reducing power when the battery voltage drops closer to the cutoff limit. That's to prevent the power cutoff under hard acceleration. You can change that behavior by lowering the cutoff limit.

It sounds like the controller phases may be shorted, not the motor. You can disconnect the phases from the motor and the battery and check each phase for a short to positive or negative battery. There should be no continuity.
