Issues in S12ZVM_FOC_Sensorless.slx simulation

ozenyavas — Mon, 18 Jun 2018 18:25:01 GMT

Hello,

I have already installed the MBD Toolbox of S12ZVM. However, when I wanted to run the example Simulink model S12ZVM_FOC_Sensorless.slx, I couldn't drive my BLDC motor. After I clicked on Build Model in Simulink, it gave me an error message as shown in the picture below. Could you please help me find out the reason for the "undefined function" issue?

Thank you very much!

Hello Daniel,

I have received another error message (Build procedure for model: 'S12ZVM_FOC_Sensorless' aborted due to an error.) after I clicked on build model button. In the diagnostic viewer this error occured in the code generation part, please see it below.

Parameter precision loss occurred for 'f16CC1' of 'S12ZVM_FOC_Sensorless/FastLoopAlgorithm/FOC/GFLIB_ControllerPIrAW_F1/GFLIB_ControllerPIrAW_SF'. The parameter's value cannot be represented exactly using the run-time data type. A small quantization error has occurred. To disable this warning or error, in the Configuration Parameters > Diagnostics > Data Validity pane, set the 'Detect precision loss' option in the Parameters group to 'none'. [30 similar]

Component:Simulink | Category:Block warning

Suppress

Ignoring priority 3 specified on function call subsystem 'S12ZVM_FOC_Sensorless/FastLoopOutput'. Priorities cannot be specified on function call subsystems since their execution is controlled by the source of the function call.

Component:Simulink | Category:Block warning

Could you please help me find out the reason why an error occurs with the parameter's values?

Thank you very much for your help!

Hi Ozen,

We need to see the error. What you have provided does not cause error - those are just warnings.

Please follow the steps shown here: https://community.nxp.com/message/985284?commentID=985284%23comment-985284#comment-902087

What is the root cause ?

Hope this helps!

Daniel

Hello Daniel,

Thank you very much for your reply. I have checked the link that you provided me, however, when I load the build_exception.mat file, I do not see root causes for the error, please see the picture below. And even though the _rtw file is populated, it gives a build error, and unfortunately I could not understand the reason behind.

Would you have any other recommendations for my situation?

Kind regards,

Ozen
