6.24.7 Traverse function (Pr. 592 to Pr. 597)
Traverse operation which varies the amplitude of the frequency in a constant cycle can be per-
formed. This function of the is designed specifically for use in yarn-winding applications in the
textile industry.
When "1" or "2" is set in Pr. 592 "Traverse function selection", turning on the traverse operation
signal (X37) makes the traverse function valid.
Set "37" in any of Pr. 178 to Pr. 189 "Input terminal function selection" 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).
