Configuring the firmware using the GUI
Before actually using the firmware, it must be configured. The term configure indicates the
act of selecting a specific driving strategy, such as open or closed loop, voltage or current
mode, and so on. Customized parameters such as current limitation, motor settings, driving
related parameters and so on are also indicated.
The firmware is configured by compiling a set of ".h" files inside the source folder and writing
a series of values as fields of #define statements. To perform this configuration, solid
knowledge of the hardware and architecture of the firmware is required. Otherwise, the
configuration tool provided inside the CD-ROM called "LV ST7MC - GUI" can be used. This
tool allows you to choose and set all the required parameters visually and enables the
software to automatically generate the required ".h" files (Table 7 shows the ".h"
configurations files related to each firmware).
For a detailed description of the configuration files and how to manually customize the
related parameters refer to AN1905 and AN1947.
7.4.3
Motor type selection
Once the "LV ST7MC - GUI" is started, the Motor Type Choice dialog box appears (see
Figure 13). In this window, you can select the kind of motor (PM brushless) and the driving
strategy (sinusoidal or trapezoidal).
The two options are:
●
"3-phase BLAC/DC (trapezoidal)" to select a PM brushless motor trapezoidal-driven, or
●
"3-phase PMAC Motor (sinewave)" to select a PM brushless motor sinusoidal-driven.
