Sabvoton 72150 Programming Problems

Post by Kimovitzh » Jan 26, 2018 11:55 am

Ok ... where do I begin.

Iv'e got at QS 205 hun motor, Sabvoton 72150 and a cycle analyst v3.
When I first hooked up the Sabvoton to my PC and began the hall angle test, it went fine, saved the new angle number (245), and did the parameter store and shut it of.
Turned et on to discover that the motor went backwards, no problem just changed the motor direction in the software (from 0 to 1), changed the numbers of poles (16), and changed som other variables - even slide recharge worked. Again with the OK's and the parameter store.
Went outside, turned it on, and it worked!

So, after first test I went home shut I down and waited a day to begin fine tuning the rest in the software.
the next day only some of the new settings worked. Slide recharge didn't work any more, even though I didn't changed the setting.
And suddenly the hall angle number changed (5), so I did the hall angle test again, but now it found a new hall angle number (145) ... every time.
So did a "Restore factory settings", shut if off and tried again and now the hall angle number returned to the correct number (245).
But none of the other settings seemed to work quite right.

All of a sudden the motor rotation didn't needed correction (it is now 0) -as if the factory restore didn't restore, odd I thought, so turned on slide recharge at tried to see if that worked, but I seemed to work backwards, when I reach 100 RPM and let go of the throttle ig just ramps the speed UP, looking at the software screen the status was 22:Slide recharge ...what the f.
And when I turned the throttle to 100% it kinda stop/reverse the motor :shock: see what I mean here - [youtube]https://youtu.be/wQE4igyEyJE[/youtube]


SO!
I tried a new PC, fresh install of the software, did the factory reset and everything AGAIN.
AND it worked, so shut it down, went for a short test, shut it down - turned it on, and then the motor went backwards, and all the problems with the settings continued.

What the hell is up, either the software is not doing what it says it does, or the controller is completely bugged.
I read all the instructions, did the OK's and parameter store, had the controller powered on before plugging in the USB, pulled the USB out before I shut it down and so on.

I've got no clue what to do next. :(

I was having the same issues until I used the key switch wire to shut it down (reset) vs the main power connection. It has been relatively reliable on saves since for me. Hall test still fails. Runs good regardless. I have some new hall sensors to install next time I pull the motor apart if I find the need.

I've got a key switch between the orange "ignition" and the battery(+) wire, if that's what you are referring to?

Purple wire on mine. It is called different things on different data sheets. Looked at the sheet I was using in the shop and has it listed as ignition wire.

It's called "orange ignition" here :roll:

I went out and looked closely at my setup. Your correct. Orange is the ignition and the one I got good results when restarting controller to set program changes. The purple I have hard wired in now and was also a issue and had my memory a bit confused. Sorry about that. I was disconnecting the battery to restart and set the program changes and getting the same issues your describing. Not sure if it matters, but when setting program changes, I switch off the ignition, disconnect the program cable and then disconnect the battery for a bit. I leave the battery unconnected if I am moving the bike out of the shop as just don't trust it just yet. When I disconnect- reconnect this way it has been successful so far.

So just to be sure.
What would you do if you make a change?

Would you then do it like this?
Edit the setting.
Press OK.
Press yes for parameter store.
Press OK.
Turn off ignition.
Remove USB cable.
Disconnect battery.

Dosen't work here.

So I've contacted QS motor as they are my supplier, and they are waiting for an answer from Sabvoton. Great service from QS, I must say!
In the meanwhile have tested numerous of combinations but still with no succes.

Update on findings.
My motors rotation from factory is backwards when "Motor direction" is "0".
After "Restore factory settings" has been done (press "Yes" -> "OK", turn key off, wait 5 sec, turn on) the software ask for "4:HALL angle test".
When the "4:HALL angle test" is done "Hall angle" is found (245), I then press "OK" -> "Parameter store" "Yes" "OK", according to document from QS -
If use QS V3 type ,the angle is about 250.
I then turn ignition off, remove USB from controller and the turn ignition on and insert USB again.
Now the "Hall angle" is (14) in the "DEBUG" page. :?

Did the entire thing again ...
Now the "Hall angle" is (19) in the "DEBUG" page. :?
I've also seen (129). But never (245) again.

So if I ignore this, and change "Motor direction" to (1) "Motor Pn" to (16), and press "OK" and "Parameter store" "Yes" "OK", the wheel turns the correct way, "Slide recharge" also works perfect.
If I change "Hall angle" to (245) "OK" and "Parameter store" "Yes" "OK", do the ignition off and ignition on, the wheel turns backwards :!: , EVEN if "Motor direction" still is (1) AND the "Slide recharge" does not work correct, it works opposite. Now it accelerate to max speed when "Slide recharge speed" is met.

This is just one of the ways I've tried, so If any one have some input as to what I might have missed, please tell me, and I can then tell if I've done it.

Mine did not set the changes reliably unless I disconnected the battery also. I never leave the battery in my bike overnight so it became evident it was getting different results when giving up with it and putting bike away for next day. This nightmare went on for near a few weeks :evil: .

Your direction change from zero to 1 will also flip- reverse the accell and decell time settings. I ended up swapping phase wires and hall wires to get the direction correct on default (zero) setting. Huge pain! I would think QS would know what is up with their motor -controller setup. Was thinking of going with one of their motors on a hub setup as I was thinking my issues were related to my gng motor. Does not sound like it.

Changing the phase wires did not help, now the "Slide recharge" just accelerate backwards :roll:
I am now quite confident that i'm having a faulty controller :(

If you decide to buy from QS, I can highly recommend them, they provide great service!

Although mine is a 96150 I think you might help.
Was working fine, I had to disconnect the motor for maintenance and now error 25 is on. Tried everything, even reset to factory default but nothing. It shows 2v only but the battery is full...
Help will be welcome!
