Parameter name
"3-phase BLAC/DC (trapezoidal)" advanced parameters
Pulse width modulation (PWM) frequency in kHz.
PWM minimum off time in microseconds (µs) to detect the BEMF.
Enables or disables synchronous rectification.
Value of dead time in µs (only if complementary PWM enabled).
Time window filter in milliseconds to prevent erroneous sampling of the current
after the PWM is turned ON.
Defines the number of counter events required to validate a current limitation event.
Sets the frequency of the sampling clock for D and Z events in kHz.
Defines in which state the unused MCI input is fixed, either "Grounded" or "Hi-Z".
Sets the blanking window after a D event in microseconds (µs).
Defines the number of counter events required to validate a Z event.
Voltage set (in volts) for Z detection.
Sets the blanking window after a C event in microseconds (µs).
Defines the number of counter events required to validate a D event.
Three methods are available: "all hardware", "alternate hardware/software" or "all
software".
fixed demagnetization time in microseconds (µs) (only with demagnetization
methods “all software”)
Allows using a different value of the duty cycle rather than the one in the run time
setting.
Value of duty cycle percentage forced during demagnetization.
Enables or disables DC current braking.
Value of duty cycle percentage of PWM brake signal.
Duration in milliseconds of the active brake.
After stopping, the motor continues to spin freely.
