Wobbulate, fixed-length and counting:E0.00-E0.11
Wobbulate function is suitable for the textile, chemical, and other industries, as well as occasions
that needs traverse and winding function. Wobbulate function means that the inverter output
frequency swings up and down to set the frequency centering around the set frequency, the locus the
operating frequency on the timeline is as shown in figure, which the swing amplitude is set by E0.00
and E0.01, when E0.01 is set to 0, the wobbulate will not work.

This parameter is used to determine the baseline of the swing
0: relative to center frequency(F0.07 frequency source).For the variable swing system. The
swing varies with the change of center frequency (the set frequency)
1: relative to maximum frequency(F0.19)For the fixed swing system, the swing is fixed.

E0.02 Sudden jump frequency range

0.0%
☆
The parameter is used to determine the value of swing and the value of sudden jump
frequency.
When the swing is set to Relative To Center frequency(E0.00=0), Swing (AW) = frequency
source (F0.07) × swing amplitude((E0.01). When the swing is set to Relative To Maximum
Frequency(E0.00=1), Swing (AW) = maximum frequency (F0.19) × swing amplitude((E0.01).
If the sudden jump frequency range is selected for wobbulate operation, the frequency
percentage of sudden jump frequency range relative to swing, i.e.: Sudden jump frequency =
Swing(AW)×Sudden jump frequency range(E0.02). When the swing is set to Relative To Center
frequency(E0.00=0), the sudden jump frequency is the variable value. When the swing is set to
Relative To Middle Frequency(E0.00=1), the sudden jump frequency is the fixed value.
The frequency of wobbulate operation is restricted by the upper and lower frequencies.

Wobbulate cycle: the time of a complete wobbulate cycle.
Triangle wave rise time coefficient(E0.04), the time percentage of Riangle Wave Rise Time
relative to Wobbulate Cycle(E0.03) Triangle wave rise time = Wobbulate cycle(E0.03) ×
Triangle wave rise time coefficient(E0.04), unit: second(s). Triangle wave drop time = Wobbulate
