VESC Tool - "R is 0" Error

Ya I now see i can just run the test from the FOC section so I don’t need to keep repeating the steps - thanks, saving some time but still the same problem.

Tried with those settings -

and still no joy - error: “R is 0”

Setting loaded on vesctool and apply ( M on top right on your screen , not Apply on the bottom ) in the vesc ? ( just asking because at beginning … set apply save …)

No voltage cut , sure of that ?

Are you able to run the motor at all using the my setting or blc mode ?

Ya I’m happy that I’m pressing M in the top right of the screen.
Currently trying the Motor Wizard, selected BLDC and the below limits

Then set the battery limits followed by selecting sensorless - I then get the gree MC Updated Logo down the bottom right and I go to run and the following happens:

So unfortunatly, I can’t even get BLDC to turn the motor

Well , problem with motor or vesctool

Can you try to run the motor in foc with FR setting?
Can you another motor to test detection

Things that I have done a couple time : erase everything for pc , drivers, folder , and re install all vesctool (older firmware )

Tried again my friend and no luck. So I did a bit more digging and the VESC Tool has a Error Terminal.

When I use the Setup Motors FOC Wizard I get the “Detection Failed. Reason: Sensor detection failed” Erros and the Terminal states:

When I use the Motor Settings - Motor Setup Wizard - FOC I get the “R is 0. Please measure it first.” Error and the Terminal states the exact same error.

When I use the Motor Settings - motor Setup Wizard - BLDC I get the Error:

adn the Terminal says the exact same error. Now the Flipsky 200A FSESC is supposed to be rated for 60V and I’ve a fully charged 14S battery. So now I’m going to go away and reduce the battery to 12S and try and re-run and I’ll give an update late tonight. Thanks a million for your help so far!

So before I changed my battery I decided to take a look at the settings more. In the Motor Settings under General - Advanced the Max Voltage Input was limited to 57V but I have a fully charged pack so I’m closer to the 58V. Changing this to 59V and away she works!

Thanks for all the help! I’m sure I’ll be back with some more queries before this is all over!

Man, we said many times on the forum the flipsky won’t handle this voltage. Flipsky 200A vesc based is basically a vesc 6 MK3 watercooled. It won’t handle spikes above 60V, 12S is safe while 14S will most likely burn your ESC. You have been warned…

Good job , yes voltage cut ! I was thinking lower value not the higher but yes these safety cut everything …

Can we have a screen shot of the value for this motor please ?

Ill screen shot everything once I get the motor running smooth but I’ve the cut off at 59V which let me get past all the errors above. Any lower and it failed

Wow, 14S with that VESC!? You’re a brave soul! Best of luck!

Let us know how things work out using 14S.

What Control Type did you select for PPM Configuration?

@tylerclark - brave indeed - I know I’m pushing it but its worth a try!
@MAC - I’ll be posting an update as I go. So far I need to get the throttle working better. I’ve it set to Nautral but its a disaster at present so I’ll need a few more hours over the coming days to iorn that out as I’m still learning myself

Did you email Flipsky and ask about running on 14s? I did. They told me it will fry. What makes you decide to do this anyways? And then you even fully charged your battery?! At least stop charge at 4.0 volts per cell / 56v!

I have my fingers crossed for you, but I predict it will fry on the first test under load. :crossed_fingers:

:call_me_hand:

I’m just learning. I have been trying “Current No Reverse” That is strange because the motor either runs at full blast, or nothing. I read that is how it works. I guess I need to apply a actual load to the motor. PID speed control gave me the most normal seaming speed control.
I see Tylerclark is also working on learning the VESC. So guys I will let you know what I learn.

Mine seems to work well on FOC. Below are the settings I get after running through the motor setup wizard:

82 is pretty high for the resistance ! It depends on wires and plugs as well , but for most inrunner I tested I was around 30 …

If I am correct running this motor at 100A , means 820w of heat on the system to cool , I don’t know if it is even possible with water …

Here is what they wrote to me. Anything about 57V and it’s problematic:

Well someone has to test I guess even if I depend on wire gauge length …
Not a big deal to charge 14s to 4.0v /cell or buy another vesc on Bangood :crazy_face: or maybe the swim back to shore or the fire in the box …

Oh Tyler if I had that from you 2 days ago I’d still have hair left :wink:

Thanks guys, and yes @Alexandre, if it fries it fries.

@Flightjunkie yes I’ve been in touch with Flipsky the past few days and when purchased - its a wait and see scenario with them and they are aware

@Bevo thanks for showing yours, Ill take a look at mine in the morning and see how it compares

@MAC sorry, im only learning myself, ill get back to you in the morning on it

Hmmm, good point. I’m running 8ga wires but 2 sets of plugs (one set at the motor, one at the esc). Maybe I’ve got a bad solder joint at the motor? It came with the coated winding leads. I really struggle to get those prepped well enough to solder
