CCS/TMS320F28027F: Instaspin lab 1C, gMotorVars.IqSet_A



Tool/software: Code Composer Studio

Hi,Good day YanMingLuo

I had finished the lab 1b, current and voltage monitored at CCS almost same as actual oscilloscope result.  Then I procced on lab 1C. But I feel I need some guide on gMotorVars.IqSet_A setting.

From the code,  if gMotorVars.IdSet_A is 10, USER_IQ_FULL_SCALE_CURRENT_A is 500, then gMotorVars.IdRef_pu should 0.02. But I run debug, it shows value -0.83333

below two lines of code also gives error :" #175-D floating-point value does not fit in required integral type"

  gMotorVars.IdRef_pu = _IQdiv(gMotorVars.IdSet_A, _IQ(USER_IQ_FULL_SCALE_CURRENT_A));
  gMotorVars.IqRef_pu = _IQdiv(gMotorVars.IqSet_A, _IQ(USER_IQ_FULL_SCALE_CURRENT_A));

My setting:

gMotorVars.IqSet_A  : 10

USER_IQ_FULL_SCALE_CURRENT_A :500

BTW, Do you have we chat?  I would like to get in contact with you. you may message me at sun_chunlei.
