this signal is ON for 0.1 s or more, the Inverter will sample and hold the analog frequency reference
being used.
The Inverter will continue to keep the frequency on hold.

frequency on hold as frequency reference 1 value of n025 so that the value will
not be lost after the Inverter is turned OFF if n044 is set to 1.
