Field Description
Space vector modulator scale factor.
depends on the PWM carrier frequency, should be set as follows:
where PwmPeriod is the value in the PwmConfig write register
group’s PwmPeriod register.
Field Description
Selects diagnostic data items for output on DAC PWM pins 0-3.
These pins are intended for use with external RC filters for
oscilloscope diagnostic display:
1 = DC Bus Voltage
2 = V phase current
3 = W phase current
5 = Speed PI Reference
6 = Speed PI Feedback
7 = Speed PI Error
8 = IQ Ref
9 = Q axis voltage Qv
10 = D axis voltage Dv
11 = 12-bit electrical angle
12 = Q axis current Qi
13 = D axis current Di
14 = A axis (stationary frame) voltage Av
15 = B axis (stationary frame) voltage Bv
