Other Parts Discussed in Thread: LAUNCHXL-F28379D,
I have had two DRV8353RS-EVM failed and I need to know why. The first one has bit 6 set on register 2. The second one has bit 6 and 4 set on register 2. I can not clear the faults. The first unit was functioning fine when I have the DC bus at 24V. When I raised to the DC bus 85V it function for a short period of time before getting the fault. On the second unit I started with a DC bus voltage of 60V. I was able to tune the current loop and when I tried to spin the motor I got the fault. I am driving the DRV8383RS-EVM with a LAUNCHXL-F28379D though an wire wrap cad to get the signals in the correct location.
The software I am using is from Matlab/Simulink Motor Control block set. I did set register 3 and 4 to the same parameters as the TI software that came with the EVM.
Thanks for your help
