Setting for the frequency threshold. The over-/underfrequency protection
function will operate if one of the following two conditions applies: The
threshold is higher than the set nominal frequency and the frequency exceeds
this threshold. The threshold is lower than the set nominal frequency and the
frequency falls below this threshold. Depending on the chosen operating mode,
either a signal is issued without further monitoring, or further monitoring
mechanisms are started.
