Figure 17: PWM frequency / pulse duty factor
The two limit frequencies of the PWM control (HI and LO) are set with the selection of the valve type. The frequency
output actually varies within this range, depending on the working point.
The following values (see “Figure 17: PWM frequency / pulse duty factor”) were determined empirically from the
behavior of a large number of individual devices of the corresponding type.
