Fixed the cogging, but thereās another, weirder issueā¦
Past a certain speed, one of the motors suddenly jumps up in speed and just generally starts behaving weirdlyā¦ Iāve heard of this happening on the unity but I canāt find any details.
Ok so previous issues aside - as soon as I turn my unity off and seal up my enclosure, the unity resets on the next power on? All values are set to defaultsā¦ This has happened twice now and at this point Iām too sick of all the crap thatās been happening to keep working today.
Iāve got a pair of FOCBoxes and they are being kinda picky with sensors. Iāve got TB motors with good sensors but motor detection always shows up as sensorlessā¦I though it was something with the temp line and a hall line being swapped (according to the casing relative to the motor based on the wire colors). Any ideas what to do about it? Iām swapping to FS 6384s in a week but I thought Iād diagnose the problem now
This is normal with sensorless, but not on the bench. With no load, even sensorless should spin up to full speed every time very quickly. They only cog when a load is applied and the speed is exactly 0.0km/h
I managed to get a set of values that spins the motors up nice and smooth, but they donāt spin as I would expect them toā¦ AFAIK they should spin to full speed on the bench at low throttle, but mine seem to depend on the throttle to change speed. It ends up looking fairly similar to a normal ābldc modeā esc.
Any ideas on why the esc keeps resetting itself? Is there a hardware reset button that Iām hitting accidentally or something?
EDIT: Is there a way to use the Unity as a normal bldc esc? When I was running on rc escās I really liked the feel of the motors and Iād love to get that response on the Unity as long as the brakes still work
Yah I mean I donāt know if saying they are diodes is technically correct but know you can measure other semiconductors in diode mode and at least it helps differentiate in this case but yah temp sense should show as a resistor and if you blast it with heat should change resistance (Iām not sure if mine is right for what the vesc expects but the hall sensors work)
Check out the control modes in the general app settings tab use ācurrent control no brakeā for typical nice riding, you might be in velocity mode or something else, if in current mode and still accelerating slow double check your voltage cut off limits and current settings for the motor and battery.
Itās not that itās accelerating slowā¦ It just doesnāt accelerate without more throttle. As far as Iāve heard motors should reach top speed almost immediately on benchtop without needing to adjust the throttle at allā¦
If the unity keeps giving me a hard time like this I might just switch back to my rc escās
PS itās in current w/ brake mode
If you are at about half throttle it should get up to max speed on the bench in a matter of a second or two. Can check out the realtime data view and the on the RT data toggle to see whatās going on current wise the RT App toggle lets you see the control input make sure all of that is right or your gonna have a bad time share some screencaps if things donāt seem to be working. Show the battery and motor config and rt app data and config pages.
Donāt judge but @Itsmedant is it possible to use a kaly deck as an emtb? it pretty much looks like the same contruction as a trampa (not esthetics lol the kaly is way better!)
It even has mtb holes for the mtb trucks.
Not sure if i should summon Ernesto?
Will get some screenshots from the VESC_tool later today showing which buttons need to be pushed to get realtime data and what screenshots are important not sure what you mean by focboc tool though (did enertion make their own copy of the config tool?)
