"3-phase BLAC/DC (trapezoidal)" advanced parameters
Parameter name
Description
Switches PWM
frequency
Pulse width modulation (PWM) frequency in kHz
Switches PWM
minimum off time
PWM minimum off time in microseconds (µs) to detect the BEMF
Complementary PWM
signal
If synchronous rectification it is enable or not
Deadtime
Value of deadtime in µs (only if Complementary PWM enabled)
Current loop
Current blanking
window
Time window filter in milliseconds to prevent erroneous sampling of the
current after the PWM is turned ON
Current event counter
filte
r
Defines the number of counter events required to validate a current
limitation event
D and Z sampling parameters
Sampling clock
Sets the frequency of the sampling clock for D and Z events in kHz
Unused MCIx input
Defines in which state the unused MCI input is fixed, either “Grounded” or
“Hi-Z”
