6.5.1 Software Parameters Tuning with PC Master Software Project File
Sensorless BLDC software is provided with a PC master software
project file for on-line software parameters tuning (see Figure 6-10).
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 Mode. Moreover, the
tuning file incorporates subprojects for a dedicated system variables
— SET PWM FREQUENCY SET_PER_PWM
— SET CURRENT SAMPLING PERIOD SET_PER_CS
— SET PERIOD FROM PWM RELOAD TO CURRENT SAMPLING SET_PER_CS
PWM Frequency and Current Sampling Period Setting
— MEASURE FREE PHASE BACK-EMF VOLTAGE FOR THE MOTOR MUTUAL CAPACITANCE EFFECT
— MEASURE FREE PHASE BACK-EMF VOLTAGE FOR THE MOTOR INDUCTANCE CAPACITANCE EFFECT
