yes. that’s the mechanical “switch” … which I will probably do.
unity fw has a boolean setting to just disable motor temp throttling which would be easy peazy. sadly this is lost in it’s transition to bldc/vesc fw5.1
This is obviously not how temp changes. But why such swings? Bad sensors? EMI? Bad wire connection? Anyway feels scary with such unreliable measurements to let VESC cut off power based on temp
Hy @All !!
Im also running into the issue with the over temp readings
Im running a dual setup with 2 focboxes and 2 aps6374s motors
Im getting the temp error also when i lift my board up and let the wheels spin in tge air so without lot of wheigt on the board
Regarding my xmatic readings the temp jumps from 54 up to 75 and then over and over till the error pops up
The motors are not very hot i can touch them with ease
Now before im going to remove the temp wire i wanna ask if a firmware update could solve this?
And my next question is which firmware can i upgrade my focboxes too without damaging them
Im runnin the ackmaniac tool btw
Thx very much guys
That’s some wild temp swings. possiboly more than noise. possibly broken cables.
Wild temperature noise should likely be addressed at hardware maybe some of these solutions.
fix broken wires.
better routing of sensor wires. ( avoid unpaired routes to avoid receiving emf. )
twisting of phase wires to reduce emf.
shielding the sensor wires from the phase wires.
as a workaround you can depin the temperature sensor wire.
Newer 5.02 beta firmware (actually 5.01 but that has other issues) has increased software low pass filtering which will take care of some noise but won’t a fix for everything.
so short answer to your specific question. It might help.
@Sharky I’ve heard of people taking shielded HDMI cables, and just using that for the sensor wires. Could also use a shielded USB cable but they only have 4 conductors and you need 6 for sensors + temp.
Is it possible to have the vesc ignore the temperature as a security (i.e faulting over it) but still displaying it?
I’ve been running motors without temp sensor ever since i started, now i have new motors with it but don’t want to risk a software based fault. Of course its there for a reason but i know my motors and have yet to bring them to a critical state. I’m just interested in the value, but not the safety aspect as stupid as it may sound.
Ah ok got it thx!!
I think ill try the isolation and if thts not fixing it ill disconect the temp wire
Tbh i dont care which temp the motors have they just should not stop at high temps i dont want to bite the street at 40mph
