I am using a hobbyking VESC in my build and it is showing some very erratic behavior. 95% of the time the motor will not spin at all or is super weak. In the realtime data tab of the tool the VESC is showing as receiving the incorrect voltage so I get the UNDER_VOLTAGE fault.
at the moment it shows 4 volts (but its a full 6s pack which shows 24.6v on the voltmeter) so there is no spin at all. sometimes it shows 14 or 15 volts and i get a very weak spin, and very rarely, it shows the correct voltage and spins beautifully as it should. unfortunately the last case only occurs about once for every 50 times i plug it in!!!
does anyone have any suggestions as to why it only works 5% of the time and 95% of the time it just shows completely wrong voltage and faults out?
once it was working fine, I go for a ride and it kept cutting off, then resuming 2 or 3 seconds later even.
ANY help/suggestions/known faults with the ESC and so on would be very greatly appreciated. I’ve tried rebooting, reflashing etc and this silly VESC just will not read the voltage correctly.
Many Thanks for your suggestions.
