The rate of change can be obtained for each sampling cycle set for the analog
input data. This function calculates the difference between each set sampling
cycle and value obtained in the previous cycle. The default setting for the
sampling cycle is 100 ms and the sampling cycle setting range depends on
the model, as shown in the following table.

Rate of change
Note If the sampling cycle is set to a small value, the rate of change will be sensitive
to small changes. If the analog data is subject to minute fluctuations, and the
sampling cycle is shorter than the cycle of fluctuation, the fluctuation will be
