It is used to set whether the parameters are modifiable to avoid mal-function. If it is set to 0,
all parameters are modifiable. If it is set to 1, all parameters can only be viewed.
6.15 Swing Frequency, Fixed Length and Count（Group PE）
The swing frequency function is applied to the textile and chemical fiber fields and the
applications where traversing and winding functions are required.
The swing frequency function indicates that the output frequency of the AC drive swings up
and down with the set frequency as the center. The trace of running frequency at the time
axis is shown in the following figure.
The swing amplitude is set in PE.00 and PE.01. When PE.01 is set to 0, the swing
amplitude is 0 and the swing frequency does not take effect.
