6.10.6 Detection of output frequency (SU, FU, Pr. 41 to Pr. 43)
The inverter output frequency is detected and output to the output signal.
The above parameters can be set when Pr. 160 "User group read selection" = 0.
Up-to-frequency sensitivity (SU, Pr. 41)
When the output frequency reaches the set frequency, the up-to-frequency signal (SU) is output. 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 op-
eration start signal etc. for related equipment.
When using the SU signal, set "1 (positive logic) or 101 (negative logic)" in Pr. 190 to Pr. 192 "Output
terminal function selection" to assign function to the output terminal.
