Hello, connected my brushless 3500 velineon motor of the traxxas ultimate, to VESC tool 3.0. During motor detection, the wheels attempt to spin but can not turn, they only budge a bit.
battery: 3S, 5200 mAH 25C. The motor configuration am using can be found here. Thanks.
Below are the faults from the terminal, for the first and last entries. What could be the problem here.

for an 3s battery, vbat_min should not be less than 9V,
charge bat. to full and try again, but at least 4s min recomended, in fact.
hello skyline, I did what you suggested but even if the voltage improves, the issue persists. Why is my current so low? Below is the current print out from the terminal:

in motor settings, general, adjust bat voltage cutoff settings
advanced , min. input voltage
maybe, it could also be tested with an 12v accu.
type of vesc?
Hello skyline, I am using a VESC6 based FSESC6.6. apparently it is using the 60FW, the one without a Mark. alright, I am going to try to set the minimum input battery cutoff voltage to 9v. I did not understand the 12v accu.
On a different note, I wish to recompile the firmware with the servo set as output, is the board i selected below the right one for the with FW:5.2, HW:60? the one without Mark version?
Thanks Skyline1970.
12v ups or car battery
servo output can be provided
thanks alooot. worked. now my motor is spinning happily xd. how can i obtain the servoout?
How do i go about that?
in app. settings, "Enable servo output on PPM-port when PPM-app is disabled." make true
Hello, I do not see any such option in any settings. Even when i choose ppm as the app to use from the general tab. Even under the ppm settings and configurations there is no such option as: "Enable servo output on PPM-port when PPM-app is disabled." . Am using FW: 5.2, HW:60, VESC tool 3.0.
Thank you for your contribution; I hope you will contribute more in the future
