4.5.4 Run the Code

To run the project code, complete the following steps:

  1. Slowly adjust the output voltage of the AC supply from 30-VAC to the build-dependent test value.
    1. Build 1: Do not adjust the output voltage.
    2. Build 2: 100-VAC
    3. Build 3 and Build 4: 220-VAC
  2. Run the project by clicking the button TIEVM-MTR-HVINV , or click Run → Resume in the Debug tab.
  3. In the Expressions window, wait until systemVars.flagEnableSystem is automatically set to "1". Set motorVars_M1.flagEnableRunAndIdentify to "1".
  4. In the Expressions window, the variable motorVars_M1.flagRunIdentAndOnLine is set to "1" automatically. ISRCount is increasing continuously.
  5. The project can now run with the values in the Expressions window continuously updating. All CCS windows can be resized according to user preference.
  6. Perform build-dependent test procedures.

    2. Section 4.5.4.2
    3. Section 4.5.4.3
    4. Section 4.5.4.4
  7. Fully halt the controller by first clicking the Halt button TIEVM-MTR-HVINV on the toolbar or by clicking Target → Halt. Finally, reset the controller by clicking on TIEVM-MTR-HVINV or clicking Run → Reset.
  8. Erase the code in the controller for the next build level by clicking Tools → On-Chip Flash, and click Erase Flash in the On-Chip Flash tab (make sure that all of the flash banks are checked) as shown in Figure 4-6. This operation erases all of the program code stored in flash. (This step is optional).
    Note:

    Do not click Cancel, turn off the power of the board, or disconnect the emulator when erasing flash.

  9. Close the CCS debug session by clicking the Terminate Debug Session button TIEVM-MTR-HVINV or clicking Run → Terminate.
