PW[N] - PWM Signal Parameters
Purpose:
PW[1] defines the offset value for PWM signals in fractions of the Duty cycle.
PW[2] defines the dead band zone of the PWM signal in the fractions of the Duty cycle.
At times, the application requires the Duty cycle value to be different from the source of
the PWM signals (i.e. offset). The PW[1] parameter is intended for this purpose.
The Actual Duty Cycle is Estimated Duty Cycle - Offset
A very low Duty cycle values may cause a motor to “crawl” when a complete stop is
desired
The dead band zone parameter (PW[2]) forces the Actual Duty Cycle to zero when it is
less than PW[2].
