today I flashed my home made(soldered everything
manually) VESC and everything seemed fine, until I tried to detect the
motors parameters. It only jumped a bit and then stopped. The bldc tool
says:“bad detection result received”. In order to narrow down the error
I disconnected the motor from the vesc. However in the realtime data tab
it says:" Fault code abs over current". The motor current says: 147A,
which obviously is not correct, since the battery current is less than
0.2A. So these two results doesn’t sound good. For the VESC I used
0,5mOhm shunt instead of 1mOhm… Can this fact cause such an error? I
did a continuity test for the MOSFETS circuit and there where no shorts
or solder bridges.
If anyone has an explanation for the errors I get or even has a suggestion to solve the problem I’d appreciate it.
