Functional principle
Both electronic module outputs are supported by the PWM function (pulse width
modulation). Specifying the time parameters produces a pulse train with the desired
pulse/pause ratio.

The pulse pause is obtained by setting parameters for period and pulse duration. The
settings determine the pulse/pause ratio.
