Setting range: 0.00–P00.03 (Max. output
frequency)
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
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 from the highest point to the lowest
one.
