Note) Regardless of the sequence of input of frequencies, acc/dec times are switched from #1 to #2 at the
lowest frequency, from #2 to #3 at the middle frequency and from #3 to #4 at the highest frequency.
(For example, if the frequency set with  is higher than that set with , the acc/dec time #1
is selected in the frequency range below the -set frequency, while the acc/dec time #2 is
selected in the frequency range of the -set frequency to the -set frequency.)
