CCS/BOOSTXL-DRV8305EVM: About proj_lab11a

Part Number: BOOSTXL-DRV8305EVM

Tool/software: Code Composer Studio

I want to make my own customed source code modified from proj_lab11a source code. In the proj_lab11a, firstly, Flag_enableOffsetcalc must be set to1 and wait until it returns to 0. Secondly, Flag_enableRsRecalc must be set to 1 and wait until it returns to 0. Finally, Flag_Run_Identify must be set to 1 and the motor starts spinning.

I want to know how to make the motor spin immediately without the above mentioned procedure (because the offsets and Rs are already known) ?

Regards,

Nantawat.

    You might disable offset and Rs re-calculation by setting Flag_enableRsRecalc and Flag_enableOffsetcalc to "0" before starting the motor if you know the offset value and set the correct parameters in user.h. But you have to use Flag_Run_Identify to run/stop the motor for calling the FAST estimator.
