Hi there, today I tried my first VESC build, and I´m starting to get the hang of it except a problem I have when braking. I´ve tried everything to solve it, but nothing has worked. The VESC is a MAYTECH VESC v4.12, which has the capacitor mod done to it (the one from the DRV, C18 if i’m not mistaken), but it still throws an error when braking. The error is the following:
The following faults were registered since start: Fault : FAULT_CODE_DRV Current : 0.8 Current filtered : -32.3 Voltage : 39.36 Duty : 0.000 RPM : 5603.9 Tacho : 151545 Cycles running : 6018 TIM duty : 0 TIM val samp : 2 TIM current samp : 4200 TIM top : 8400 Comm step : 0 Temperature : 36.05 Fault : FAULT_CODE_DRV Current : -12.4 Current filtered : -25.2 Voltage : 39.34 Duty : 0.000 RPM : 4953.0 Tacho : 152086 Cycles running : 2857
To be more precise, what happens is that it cuts out and then starts braking again, and it usually only happens when braking close to 100%…
If needed I can post all my VESC parameters, I’m also using HUB motors and FOC mode in a 10s setup. I’m also using Current control.
Has anyone else faced this problem? And if so, how did you fix it?
