Sensorless BLDC software is provided with a PC master software
project file for on-line software parameters tuning (see
This file supports:
• Remote application control
• Key software parameters modification for:
– Current parameters tuning
– Start-up parameters tuning
– Speed parameters tuning
• PC master software "oscilloscope" windows with required
variables
The remote application control uses the same control page as described
in PC Master Software (Remote) Operating
tuning file incorporates subprojects for a dedicated system variables
