Did you use the CA with my controller ? What does the CA do to the throttle signal ? All these test are on the MAC ? How many phase amps max ?

yes. should do nothing as it's "pass through". yes. max 210*.7=150ALebowski said:

TPS= ThorttlePoSition 
nice case mod. think i will just mill down the fins on the bottom. i wanna use it with up to 120A so that's half of what it's meant for. thanks for being the guinea big and all of those nice pics

I can help with at least one of the questions.
TPS is throttle position sensor, very common term in automotive circles, not that common on ebikes.

thanks. so this is equivalent to "our" hall sensors which give the throttle position. correct?SplinterOz said:
so this sentence "(6) TPS Low Err: Hall active pedal, if lower than the value, report the fault of TPS Type, Range:
0~20" would translate into "(6) TPS Low Err: Throttle low voltage error. If throttle voltage is below that value report an error. Range 0-20% of 5V"

i'm happy to do it. i like kelly controllers from the first time you recommended them to me. and i still like my "old" trapezoid controller. now with the sine-wave types they turned silent, which is very much welcome.crossbreak said:nice case mod. think i will just mill down the fins on the bottom. i wanna use it with up to 120A so that's half of what it's meant for. thanks for being the guinea big and all of those nice pics
and i'm sure that, for the power we need, cutting away that lower fins is a good idea to make the case low profile.
in my case i have very special requirements regarding cable routing, so the case needs to be closed on both sides and the wires are routed directly into the bike's frame through holes in the controller's case and the frame.

it seems the halls are now properly recognized and the controller works as it's supposed to.
what still is not ok it, that there is some strange behaviour at full speed. the controller doesn't maintain speed/rpm but reduces wattage more than needed, the speed goes down and it accelerates fully again. so more like an on/off behaviour.
can this be solved with the throttle PID parameters? i would like to know before i start to change values without knowledge.

I have one question about these controllers, do they offer field weakening? I don't see anything particular in manual, except for max rpm setting. So, if my motor can do 3000 rpm on 48 V, and I set max rpm in controller to 5000 rpm, do you think that it would apply field weakening? Thanks

i was interested to know this as well... maybe this has something to do with my strange full speed rpm issue?!riba2233 said:I have one question about these controllers, do they offer field weakening?

Maybe it is again the oversaturating of the motor ?

how would you do that? my no-load speed sits at 2000rpm. if i go zero rpm to full rpm instantly i see rpms of around 2300. this settles to 2000rpm after some seconds. 2000rpm sounds reasonable rpm for 48v and the 8T mac. but i can't say how much it should be exactly. i could install the old kelly and measure speed and compare.riba2233 said:
but what setting would you change to acchieve what you suggested to test?
if the motor works well with trapezoid controller, shouldn't it work also well with FOC or at least it should be possible to adjust timing settings to make it work well.Lebowski said:
Im not absolutely sure, but i have in mind that the MAC works well together with the Adaptto. i once read a bit in a russia thread.

i agree with you madin88. and if lebowski's thoughts would be right the problem should disappear at 500W power input, but they don't. the motor/controller behaves the samemadin88 said:

thinking about it, that's a VERY good idea to look at. i will order some genuine honeywell SS-41 and replace the ebay ones that are installed. any suggestions on even BETTER hall sensors to use?madin88 said:
btw: halls are used only for start, and they will be discarded after the motor has reached some tens or hundreds of rpm. so replacing the halls will/may help with "auto config" feature and start from stand-still only, but that is very important.

this is my bike in highest gear showing the massive overshoot when going WOT from a stand still. it accelerates up to almost 100km/h and then settles at 62km/h. max controller rpm is set to 10.000rpm just to see if helps, which it doesn't. setting it to 1.000 it limits rpm to the desired value.
the CA is for monitoring only. i connected a normal hall throttle directly to remove any possible source of error.

i don't know if the inertia of going WOT with a lot of amps allows the motor to turn faster than it normally would. is this possible with this kind of motor?

i did some more testing and comparing to the old trapezoid kelly controller.
as you can see the old controller runs at a higher rpm. and is around 15-20% faster at no load speed. changing max rpm, Kp and Ki parameter, Err rpm or anything else doesn't change a bit. and i have no idea else what to do. there is just nothing that you could adjust.
