Part Number: TMS320F28027F
Other Parts Discussed in Thread: MOTORWARE

Hello,

E: \ ti \ motorware \ motorware_ 1_ 01_ 00_ 18 \ sw \ solutions \ instaspin_ Foc \ boards \ boostxldrv8305_ RevA \ f28x \ f2802xF \ projects \ ccs \ proj_ Lab10a

I found that the first startup was normal, but on the second startup, I found abnormal noise and abnormal phase current. Why is this? Replace with proj_ The lab11a program does not exhibit this phenomenon

    Looks there is no any issues on the current waveform. What do you mean abnormal noise and abnormal phase current? Can you have a clear and zoom-in waveform to show this issue.
