This function applies to the industries where traverse
and convolution function are required such as textile and
chemical fiber.
The traverse function means that the output frequency
of the VFD is fluctuated with the set frequency as its
center. The route of the running frequency is illustrated
as below, of which the traverse is set by P08.15 and
when P08.15 is set as 0, the traverse is 0 with no
function.

of traverse
Traverse range: The traverse running is limited by upper
and low frequency.
The traverse range relative to the center frequency:
traverse range AW＝center frequency×traverse range
P08.15.
Sudden jumping frequency＝traverse range
AW×sudden jumping frequency range P08.16. When
run at the traverse frequency, the value which is relative
to the sudden jumping frequency.
The raising time of the traverse frequency: The time
from the lowest point to the highest one.
The declining time of the traverse frequency: The time
