<b>System Frequency (Hz)</b>
Specify the system fundamental frequency, in hertz, of the input signal.
<b>Under Frequency Setting (f <<)</b>
Specify under frequency setting ranging from 1% to 20%.
<b>Over Frequency Setting (>>f )</b>
Specify over frequency setting ranging from 1% to 20%.
<b>Ride Through Time Delay Setting (t <<)</b>
Specify ride through time delay ranging from 0.1s to 30s for under/over frequency ride through.
