I have an issue during the setup of my Vescs (while adressing the vescs for canbus) the master vesc kept disconnecting from BLDC then the slave vescs lights turned off so i unplugged the power to them both now neither one will power up or connect to BLDC, motor detection for both vescs worked fine and all settings saved previously. I have posted some images below i cannot see any faults with the pcb, any help or ideas would be appreciated!
-12s ( 2 x 5000mah 6s packs in series)
-192kv SK3 motors
-VESC X
I’ve had 2 sets of enertion vescs fail with canbus. I attributed mine to bad solder connections on a r spec motor. Were you doing motor detection at the time?
interesting thanks ill have a look through that thread. I had already done the motor detection on both vescs.I was just setting up the addresses when things went a bit nuts. its a tad frustrating lol
Do the vesc still light up when you open them, if not can you check if the can tranceiver is broken. This kind of damage occur when you short the can connection.
I’ve bought 2 new motors, my concern was that the slave motor was taken out as well.
I will be going with a Y connector splitting the ppm signal next, just waiting for my vesc 6’s.
Appreciate your advice bud, thanks for replying.
So just to confirm I’m testing from the c25 cap to the 5v and I should get open circuit?
Between C25 and 5v - open circuit
Between C25 and can H - short circuit
Between C25 and can L - short circuit
Between C25 and gnd - short circuit
Between 5v and gnd, canH, canL, gnd - open circuit
