3.5.2 Setup Hardware Board Parameters

The user_mtr<1/2>.h is where all user parameters are stored for motor control. The maximum phase current and phase voltage at the input to the AD converter, these values are hardware dependent and should be based on the current and voltage sensing and scaling to the ADC input. The number of current sensors and voltage (phase) sensors used are defined in user_mtr<1/2>.h that are hardware dependent.

The "user_pfc.h" is where all user parameters are stored for PFC control. The maximum current, AC voltage and DC voltage at the input to the AD converter, these values are hardware dependent and should be based on the current and voltage sensing and scaling to the ADC input.

All of the configurable parameters are defined in the user_mtr<1/2>.h and user_pfc.h files. These parameters can be calculated using the TIDM_02010_DMPFC_Hardware Parameters Calculation.xlsx Excel® spreadsheet. This file is included with the TIDM-02010 archive file at the folder ..\solutions\tidm_02010\docs to calculate these values and copy these parameters marked bold to user_mtr<1/2>.h and user_pfc.h as shown in the following codes.
