3PH PMAC or BLAC (Sinusoidal Driven) Motor Advanced Settings

Clicking the "Advanced Settings..." button opens the "Advanced Settings" dialog box (see
is where the advanced parameters for the 3 Phase PMAC Motor with Sinusoidal waveforms are set.
There are 4 parameters that are specified by the user:
a. Pulse Width Modulation (PWM) Frequency in kHz
b. Dead Time Value - select from available preset Dead Time duration values in microseconds (µs)
c. Stop Condition
– Free Wheeling - after Stop, the motor will continue to spin freely
Note: Only the Free Wheeling Stop Condition is available in the Reference Design Kit at this time.
– Active Braking
Note: This option is not available in the Reference Design Kit at this time.
Note: The Brake Voltage setting is not available in the Reference Design Kit at this time.
Note: The Brake Minimum Speed setting is not available in the Reference Design Kit at this time.
d. Ph/F curve - Software uses this curve to set the value of the Phase Shift based on the actual value of
the rotor frequency when the "Set Phase Shift according to Ph/F Curve" option is set in the main
window. The curve is a linear interpolation between two knee-points.
– First Knee-Point Phase Shift - sets the value of Phase Shift of the first knee-point of the curve
– First Knee-Point Frequency - sets the value of Frequency of the first knee-point of the curve
– Second Knee-Point Phase Shift - sets the value of Phase Shift of the second knee-point of the
curve
– Second Knee-Point Frequency - sets the value of Frequency of the second knee-point of the curve
