The above parameters can be set when Pr. 160 = 0.
Up-to-frequency sensitivity (SU, Pr. 41)
When the output frequency reaches the set frequency, the up-to-frequency signal (SU) is out-
put. The Pr. 41 value can be adjusted within the range 0% to ±100% on the assumption that the
set frequency is 100%.
This parameter can be used to ensure that the running frequency has been reached to provide
the operation start signal etc. for related equipment.
When using the SU signal, set "1 (positive logic) or 101 (negative logic)" in Pr. 190, Pr. 192 or
Pr. 197 to assign function to the output terminal.
