2) Switching by frequencies - Automatically switching acc/dec times at certain frequencies
	Title	Function	Adjustment range	Default setting
		Acceleration/deceleration switching frequency 1	~ Hz
		Acceleration/deceleration switching frequency 2	~ Hz
		Acceleration/deceleration switching frequency 3	~ Hz

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.)
