Generally, each of the four combinations of dip-switch settings can be used.
With the lowest frequency, the lowest hysteresis is obtained, the PWM
signal, however, is still slightly audible, whereas with the highest frequencies
practically no noise is perceptible.The sensisitivity and hence the excellent
functionality in closed-loop control applications, however, is guaranteed with
all the four frequency settings.
