    Nanjing far driver controllers

    Go to parameters menu after auto learn is complete and hit save. This will write data to controller and you can power it on and off with out it restarting auto learn. I have 5 of these controllers. One of my trikes hits 27000kw on a 28s pack

    Thank you Bartosh. this fixed the sport mode activation (go to port menu click pb3 tab and click off the SW..) looks like my supplier changed that value on me to probably help there returns etc..

    got it to work just now, bad power wire for testing. its sometimes hard to keep track of all new wires when having 2 setups( 2 motors 2 controllers etc) this build i wanted all about tq and since the 2 motors would provide about 110-120 nm at shaft, i can gear this tall and have some good top...

    I have it all apart as I'm painting all frame/parts etc. but I can recheck later, in the meantime i did make a video of it not working and i do show the all software pages at the very end of video( you can pause frame to read it). this is a complete aluminum dirt bike i made out of a few junk...

    anyone else notice in the newer batch of em150SP sport mode is activated a little differently?, i have a total of 3 motors (qs 138 mid) and 3( em 150sp). My very first controller, its sport mode was how everyone describes here, simply take the yellow/white and bridge it to ground for continuous...

    great info, thanks. for the qs205 motor, this is a hub motor right? did you have to make any modifications to make it a midedrive? using the magura throttle is there any modifications or settings that need to be made with the votol controller? would you use the magura throttle again? which...

    Throttle dead zone fixes

    if my throttle has a built in switch to turn the throttle on and off(ignition key) would that work as the fail safe? instead of adding a switch to the positive?

    I was surprised you could get one. when I bought my combo (em150 + 138 motor) from supplier I ask about the em200 and they said the refuse to sell them anymore just are not reliable enough at the moment until further updates. I was def interested in a bigger controller but also the price is a...

    is there any truth that a lower flux has more linear tq? where higher flux increases rpm but by diminishing a little bit of tq along the way? just curious because my application (off road scooter- All out of aluminum) im only interested in tq, it is just too dangerous to go faster then 30mph...

    it is SiAECOSYS, Damon is the sales person. they have been good with effort helping me with questions, especially with the language barrier but always difficult to get the correct answers to the questions. so does this sound right for me to change the flux? sport mode -2500,2500 high mode...

    this was a quote above from larbs answering Silverline about what do the two numbers in flux weaking actually mean? so I understand larbs is saying it is for dual voltage and most run single voltage so it that case set the two values the same. I also notice from users here "silent endo"...

    the parameters set right makes sense, because I did forget to mention the motor gets hot under normal riding (just cruising around) I thought that was a red flag. but I never touch flux weakening or anything, but I did adjust my throttle min and max because I had a dead band at beginning. I...

    I finally got the 138 mid motor and the votol em150 SP controller all hooked up to a homemade aluminum scooter I built. this thing is way overkill (it wheelies). one issue I’m having is there seems to be a lot of engine braking when you let off the throttle, kind of like regen and it’s very...

    Im new to shunt mode, but can you tell me the advantages of the way you did it, instead of just raising the bus bar current to 170a in software. Im guessing raising it in software might not actually do any increase and by manually doing shunt mode will?

    nice video!, any reason to solder the sport mode? or just keep it simple since its the only mode you use? for your busbar current you found 140 to be best? for the qs 138 motor is your shift angle -60? I believe mine came from factory at -120

    so do I get a volt meter and measure the throttle signal wire beginning point and end point ? if there is a way to do this with out the motor to spin would be ideal since I don't have it secure. also do you put positive meter terminal on signal wire and neg terminal on the throttle neg to see...

    ok then no worries, I just read at beginning of this thread that all that is important is the phase angle and the poles for the manufacture to set up for you motor before they send out then all rest are up to you to change, like bus bar current etc... so Im assuming they don't even bother with...

    i just connected a 21s bms with lcd 300 amp , once I turn on controller - voltage jumps around then goes to zero and stays there? I have all wires correct, I don't understand. also I cant connect to the lcd screen. says connecting to bms then turns off. anyone had experience with this? thanks

    so on sport mode yes, I just got it to switch by touching it with ground, but now I seem to run into more issues. I noticed on page one my model was set to em 100 so I put it to em150 and saved. I then noticed it wont even get recognized by the software now. I tried it with the older can bus...

    I just got my em150sp and qs138 motor connected to the software. Here is a pic of my throttle settings. when I twist throttle the motor doesn't move until about 1/4 turn of throttle. Is there any adjustment so it is more sensitive? and how do I know that it recognizes what full throttle is when...
