6.19.3 Traverse function (Pr. 592 to Pr. 597)
Die Funktion ermöglicht den Betrieb mit einer zyklischen Änderung der Ausgangsfrequenz. Die
Funktion wird beispielsweise in der Textilindustrie bei Wickelvorgängen verwendet.
The above parameters can be set when Pr. 160 = 0.
When "1" or "2" is set in Pr. 592, turning on the traverse operation signal (X37) makes the tra-
verse function valid.
Set "37" in any of Pr. 178 to Pr. 182 and assign the X37 signal to the external terminal. When the
X37 signal is not assigned to the input terminal, the traverse function is always valid (X37-ON).
