Hi! My ACIM is working fine and my final program is based on lab05a, because of my motor type(it has internal break). First I activate the motor( gMotorVars.Flag_enableSys=1; gMotorVars.Flag_Run_Identify=1;) in order to recalibrate the offsets. I am waiting until the est is online(if(EST_isOnLine(ctrlHandle->estHandle)==1)) and I stop the program( gMotorVars.Flag_enableSys=0; gMotorVars.Flag_Run_Identify=0;). Now my program is waiting for the user to apply a command. But after that it takes around 0.5-1s until the motor reacts.
gMotorVars.Flag_enableSys=1; gMotorVars.Flag_Run_Identify=1; gMotorVars.Flag_enablePowerWarp=0; gMotorVars.Flag_enableOffsetcalc=0; gMotorVars.Flag_enableRsRecalc=0; gMotorVars.Flag_enableUserParams=1; gMotorVars.Flag_enableForceAngle=0;
This is not happening when I am using simple scalar control(lab01b). How can I prevent this start delay? Am I doing something wrong with this initial BIAS recalculation? Am I not starting properly the motor?
In fact I can hear very quiet noise comming from the motor immediately after turn on sygnal. Should I try to increase motor max current, torque reference value or any other parameter?
It is very annoying. Should I try to adjust lab11a by disabling the speed controller there?
Thanks!

You may take a look at chapter 10 of InstaSPIN-FOC and InstaSPIN-MOTION User's Guide (Rev. I) http://www.ti.com/lit/ug/spruhj1h/spruhj1i.pdf

As mentioned above. Set the right offset values in header file if you want to bypass the offset calibration.

You can keep using lab05a.
