VESC Tool - all the settings that matter

[@loucam-l6214]

Could you give some insight on what "Duty cycle current limit start" is at 9:41? Mine is currently set to 85% by default. My e-skate seems to top out around 45 kmh despite my erpm limits making my theoretical top speed 60 kmh. I was just wondering if this is another value that should not be touched, or if it could help with my issue. Thank you!

[@fess9867]

IIUC It's the duty_cycle percent at which vesc starts scaling down the max motor current. this avoids abrupt cutoff of current at max duty_cycle. on an esk8 you want this or you get a stuttering at full pin, which can throw you or cause speed wobbles.

[@loucam-l6214]

@fess9867 funny you should say that because shortly after my comment, i set the limit start as the same value as max cycle. I almost fell of at top speed because of the hard limit lol.

[@default19in]

Tx so much for providing this knowledge.

Ciao, video interessante, ho acquistato un flipsky 75100 V.2 pro, montato su un monopattino elettrico con motore 500 watt, quali sarebbero i parametri da cambiare per avere un miglior rendimento stradale? Grazie.

I set field weakining to 10a, my engine accelerates even when I let go of the accelerator, and to stop it is necessary to brake, or if I'm driving, it continues accelerating but has no power, is this common?

[@surfdado]

@@EBIKESBR at 10A it’s not common, no. My best guess is that it’s a result of a poor motor calibration but your best bet is to ask about it in the VESC project discord

[@EBIKESBR]

@@surfdado ok thanks!

[@EBIKESBR]

Could you help me, I had a problem with my bike, it was jerking and without power, I discovered that the problem with my controller was the Erpm configuration, so I left it in default, and the problem was solved, but, when using the mobile app, and use a profile , the erpm unconfigures again, and the problem returns! Even saving the erpm on the cell phone itself, it does not save the configuration in the cell phone application. Is there any way to solve this? Because I need to use 2 profiles, one for full speed and the other to make it weaker, but I'm not getting that , due to ERPM disconfigures when using the app on a cell phone...

[@surfdado]

Sounds like a bug in the VESC Tool to me. Have you reported this problem on vesc-project.com or on Github?

[@EBIKESBR]

@@surfdado yes it was a bug! I uninstalled the app, and installed it again, and now, when opening the vesc program on Windows, I can send the changes to the Android app, before it was not sent, and when opening the app on my cell phone, it did not recognize the changes made on the Windows, but I managed to solve it! Your videos are very easy to understand and that's how I was able to put together my project! thanks! Sandro from Brazil!

Hello Surfdado, I hope you can help me. I’ve just installed a new VESC controller in my Trotter. I followed all the steps (motor detection, custom configuration values, IMU detection), all with Float package disabled. Everything seems to work perfectly. When I’ve finally enabled the float package, the motor started to jump like a wild horse. I’ve switched off the board immediately. Now the board doesn’t work properly. I’ve tried to do a new motor setup and start all the process from the beginning, but the result shows very low current and very high resistance, and the hall sensors are not detected (sensorless). I’ve repeated the motor setup several times, and sometimes an overcurrent fault has been raised. Any idea of what’s going on? Thanks in advance.

[@surfdado]

It sounds like you might have broken your controller, those symptoms are not very encouraging. Also, as far as I know the Trotter foot sensors are reversed from normal onewheel sensors, so the float package cannot be used. Instead a custom Gosmilo version is needed, not sure where you can download that

[@floatingtrescantos]

@@surfdadoyou are right. I’ve re-installed the old controller and the Trotter works. What I think it has happened is: I installed the new Gosmilo pressure sensor that works with normal logic (not inverted), but the custom float package already installed had the inverted logic active. So when I activated the float package the motor started to spin without pressing the sensor. The board was leveled with the wheel on the air (allowing free spin). But I’m not sure it was enough for burning the controller. What do you think?

[@awakekiwi]

@@floatingtrescantos How did you go. Have you tried a full reboot of firmware and floatpackage? I have a trotter with ubox but im using spintend foot sensors so i can use the standard floatpackage and ive had no issues.

[@floatingtrescantos]

@@awakekiwi Hi. Finally I contacted with Andy Liu (Gosmilo) and I returned the controller. They tested it and told me that the controller was OK. They updated the firmware and sent the controller back to me. I’ve installed it and now it works perfectly.

[@awakekiwi]

@@floatingtrescantos good stuff. Im going to try and fit a second 60v 16s2p battery pack in the front next to the ubox. ive already removed the middle aluminum wall to make room. It will be a fun challenge but this will give me 16s4p worth of amps and range. My original trotter 48v battery wasnt up to the job.

[@EBIKESBR]

What is the best mode for a bike with a mid drive, duty cycle or current motor?

[@surfdado]

Sorry, not sure - we run current control on my son’s e-bikes and we’re happy with how it performs. Never truly tried duty mode

[@GPeter7]

Hi, I have a weird problem with my 84v VESC board with Tronic 250r it was working fine almost for 100 miles and I was quite happy, but then one day when I started riding it, I got a pushback around 10mph from that moment (battery was not overcharged), I didn't change any settings previously, I check all settings and they all looks good. I even reinstalled firmware on it, and then did a fresh setup from scratch, still had the same result. I checked the battery and motor, and everything is in good working order, any advice what it can be??

[@surfdado]

@@GPeter7 you should know by now that there’s no such thing as mystery pushback. Every pushback has a reason and that reason is shown in the AppUI screen. Find out what it is and then go from there. If nothing shows up then it may be the IMU but that’s very rare

[@GPeter7]

@@surfdado Yes, I know that, but there is nothing in the App UI screen, no errors or any messages about it, also IMU I did reset and re-calibrated as well, but it didn't help. Also, I did check the battery under load to see if there was any strange sagging but nothing

[@surfdado]

@@GPeter7 next step would be to look at logs. Probably best to troubleshoot this on the Vescify Discord instead of KZbin 😂

[@GPeter7]

@@surfdado Thank you, I appreciate your help in time

[@EBIKESBR]

I'm trying to configure the vesc tool so that I can use a potentiometer on the adc2 input, so that it works as a pedal-assisted power regulator on my bike, I use an accelerator on adc1 and a common cadence sensor, but it is dangerous to use the assisted pedal if you are using a profile with a lot of power, my intention is not to need to use a smartphone to change the profiles but just a way to change the assistance...

[@surfdado]

Yes, I have seen your post on the Vesc discord. It looks like you will need to program your own package either in Lisp or in C

[@EBIKESBR]

I adjusted the field weakining to 10a and when I accelerate the engine it doesn't stop, it stays accelerated, what could it be? I made all the same settings as in the video, I use a Flipsky 6384 motor for testing, with 0.02 the motor does not accelerate, thank you for posting this incredible video!

[@surfdado]

It keeps running even though throttle input is 0? This may indicate a problem with your controller. You should contact the vendor about this

[@nomannosher8928]

in 3:14, how motor current can be greater than the battery current. if battery can supply 35 amps, then how motor draw 120 amps.

[@surfdado]

this is standard in brushless motor control - motor amps are always higher than battery amps, just google/youtube it if you want to learn why

[@Calibike]

There are power caps on the vesc. They absorb amps from battery at battery rate. When output the caps provide 100a+

[@jensfalck_TheSwede]

One of the values should be 0.01 you said and that it should be so by default. But mine reads 0.1 Did you mix the numbers up?

[@unitedxhatersdownhate4813]

are you sure about the slow abs ? everything I checked online they all said to leave on .. also many people started to have problems with slow abs off. I am confused why Benjamin turned that off on the new update

[@surfdado]

@@unitedxhatersdownhate4813 slow abs has always been a dirty hack for low quality controllers. Increase your abs max current - but “absolute max” should mean absolute, not just meh it’s fine if you exceed it for a second…

[@ArdCustoms]

Hello, if you got the new tronic x12, can you tell me more about this controller please?

[@edinspiegel]

Hey there! Insanely helpful video! I have one question though: when calculating the battery voltage cutoff start & end - I should only use the number of cells in series right? because (at least as far as I understand) the ones in parallel don't count towards voltage right? Thanks in advance!

[@surfdado]

that's correct - just the series count matters

[@edinspiegel]

@@surfdado awesome! Thank you so much for replying!

[@AydinAdn]

A question to add to this... Are you sure the battery start end parameters are.correct way around? Wouldnt the battery voltage cutoff begin parameters be where the battery is cut off and battery cutoff end indicate the voltage that the cells must recover to? So say I want to cutoff at 37.5v and end the cutoff once the battery recovers to 40

[@Suprised1]

When you say the battery aps are linked to the battery i'm curious.... I have a dv4 maxer x with max battery amps 40A and my pack can do more than than. wouldnt the esc limit this to 40 amps? I set it higher than 40 A and was thrown on my face :

[@edinspiegel]

Hey there - I'm sorry it's me again - I have another question and I absolutely don't know where else to ask it - for battery current max regen - should I stick with the maximum continuous charge rate described in the battery specs (for me that would be just 5 amps)? or is it fine to go above that? - I don't know if it is relevant but the bms is built into the battery - thank you again - and sorry to spam your comments like this.

[@surfdado]

Due to the bms most likely being able to cut power if the regen current is too high, it’s probably best to limit regen current to the battery specs

[@edinspiegel]

@@surfdado Alright I will do it that way! Thank you so much for answering again! I've been struggling with this question for the last 2 days - so thank you so much for clarifying!

@surfdado I got the vesc program connected to my makerbase84200 it is using a thumb throttle connected by wires on a escooter ran into a issue don't no what cause or how to fix I full throttle it it clunk spin motor shaft a quarter turn or less red light comes on I slowly creep the throttle to a certain point the motor spins green light comes on it spins I let the throttle go while the motor spinning accelerate full throttle it again it still spins green light on it has no point we're give it a little acceleration while motor spin it goes slower neither it just at 1 fast speed and the throttle is weird it has no good response I go at least half way throttle be fore motor move so I have 3 problems speed of motor max 2 acceleration motor from throttle 1 throttle response sensitivity not correct

[@Calibike]

Can you run the motor using keys on a cell phone. Like up down keys

My float package is the public float package available directly in the VESC tool

[@surfingonwheel]

@@surfdado ok, so where I can get it? you provide the VESC controller too? or possible to design one?

Good thing I know all this so I don't need to watch. JK I'm gonna watch it anyway.

[@EBIKESBR]

I discovered that the problem activating field weakining was the inertia of my reduction system in my project, and there is nothing wrong with the module, now I'm trying to configure a very smooth acceleration, but not too "slow" to avoid the excessive jerk it causes blow the clutch bearing! I configured the curve more "negative" but the drag decreases a little but it is very slow to reach high speed, I am leaving my 6384 motor with only 60A and a limit of 120A, and it is very strong! I'm using a 13-tooth sprocket and a 60-tooth gear, and this larger gear is connected to a shaft with an 11-tooth mini motorcycle sprocket, and is connected to a t8f chain, on a 54-tooth sprocket, my project this is it: kzbin.info/www/bejne/nHu7aHaGhZekpK8si=xgv0GY4wHPh2G4bZ
