☆
If the absolute value of deviation between PID setting source and feedback source is greater
than of the parameter, the inverter starts only when PID output frequency is greater than the wake-up
frequency to prevent the repetition of the inverter starts.If the inverter is operating, when PID
feedback source is greater than setting source and the output frequency is less than or equal to
(F7.48) sleep frequency, the inverter goes to sleep after (F7.49) delay time and performs free stop.
If the inverter is in the state of sleep and the current run command is valid, the absolute value of
deviation between PID setting source and feedback source is greater than of PID start deviation
(FC.02), when PID setting frequency is greater than or equal to F7.46 wake-up frequency, the
inverter will start after (F7.47) delay time.
If you want to use the function of PID start deviation, PID stop computing status must be set to
active (E2.27 = 1).

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.

The parameter is used to determine the value of swing and the value of sudden jump
frequency.
