Dear sir,
I have DRV8353RS-EVM , LAUNCHPAD-F280025C and Hub motor .
(Note:- I am using 24 to 30 volt power supply and my hub motor max voltage are 48 volts and 102 hz frequency)
Recently I have complete the DMC_Level_1 as per user guide but as I move forward to DMC-2 I am facing the following issues and question.
1) At low speedRef_hz = 10, motor spin fine with no fault (Default max_current = 6 amp and over_current = 7.5).
2) As I increase the speedRef_hz = 25 , I got overcurrent fault issue. (as we know default overcurrent in firmware is 7.5 amp, when I set that to high around 12 amp, then I able to run the motor again).
3) I found the same issue on this forum, I get one solution to set the overcurrent limit by increasing and decreasing the dacVIH and dacCVIL inside the firmware. is it fine to do that in my case ?
4) what is the cause of current unbalance fault?
Regards,
Gaurav
