FR-A700 EC 6 - 309
6.14.6 Detection of output frequency (SU, FU, FU2, FU3, FB, FB2, FB3, LS, Pr. 41
to Pr. 43, Pr. 50, Pr. 116, Pr. 865)
The inverter output frequency is detected and output to the output signal.
Up-to-frequency sensitivity (SU, Pr. 41)
When the output frequency reaches the running frequency, the up-to-frequency signal (SU) is
output. The Pr. 41 value can be adjusted within the range ±1% 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.
