Tra vers e freque ncy functi on is suitable to indus tries such a s textile, fi ber and so on, and to applications
which require travers ing and w indi ng functions.
Tra vers e freque ncy functi on means that the invert er output frequency i s traversi ng up and down around
the set frequency. The operating frequenc y l ocus with time axi s is s hown as fol lowing diagram, in which
the amplitude of t raverse is set by F4.07. When F4.07 is set to be 0, i.e. tra vers e range i s 0, the traverse
freque ncy function will be inactive.
Fig. 6-15 Traverse Frequency Ope ration Di agram
Tra vers e freque ncy range: trave rse operat ion frequency limits by upper and lower limit frequency.
Tra vers e range relative to the cent er frequency: amplitude of tra vers e AW = CF
AW range F4. 07
Kick frequency = ampl itude of trave rse AW
Kick Freque ncy Range F4.08. I.e. the kick frequency i s
the value relative to ampl itude of traverse at traverse-frequency operat ion.
Tra vers e freque ncy ris ing time: the time required to rise from the lowes t traverse frequency to the
highest traverse frequency.
Tra vers e freque ncy fall ti me: t he t ime required t o fall from the highest traverse frequency to the lowest
traverse fre quency.

Fault auto-reset times : used to set the auto-reset ti mes when inverter choos es fault auto-res et. If this
val ue is exceeded, inverter will wait for trouble shooting.

Set output frequency detection value and the delay value of output action dismi ssed, as shown by
following f igure :
W hen the invert er output frequency reaches the set frequency val ue, this function can regulate i ts
