When the set frequency is within the range of
jumping frequency, the VFD runs at the
boundary of jumping frequency.
The VFD can avoid the mechanical resonance
point by setting jumping frequencies. The VFD
supports the setting of three jump frequencies. If
the jump frequency points are set to 0, this
function is invalid.

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 follows, of which the
traverse is set by P08.15 and when P08.15 is set
as 0, the traverse is 0 with no function.

Amplitude of wobbling frequency: The wobbling
frequency running is limited by upper and low
limits of the frequency.
