Choosing the right firmware

The motor control firmware is arranged according to the kind of motor to be driven and to

the driving strategy. See Table 6 to choose which firmware should be used.

Together with the installation of "LV ST7MC - GUI" the firmware source code is installed on

the PC inside the installation folder under the "LVK_Firm" folder.

Each firmware is stored inside the working folder under the same name as the firmware

itself. The following files are present inside each working folder:

–a ".stw" file: STVD7 workspace file.

–a ".stp" file: STVD7 project file.

–a "source" folder containing all required .c and .h files.

Note:

We suggest making a backup copy of the original working folder for each firmware. The

following procedure modifies the original content of the workspace folder without leaving the

possibility to return to a previous step.
