5.11.7 Output frequency detection
The inverter output frequency is detected and output as output signals.
Output up-to-frequency sensitivity (SU signal, Pr. 41)
●
Up to frequency (SU) is output when the output frequency reaches the set frequency.
●
The Pr. 41 value can be adjusted within the range ±1% to ±100% considering the set frequency
as 100%.
●
This parameter can be used to check that the set frequency has been reached, and provide signals
such as the operation start signal for related equipment.
