Chapter 7 Basic Functions
ADV-03 Acc S Start: You can adjust the slope of the curve when you set the Acc/Dec pattern as S-curve. This is used
to adjust the curvilinear ratio of S-curve when acceleration begins. The curve ratio sets the ratio of the curve
acceleration of the 1/2 frequency on the basis of a half of the target frequency. For example, if ADV-03 Acc S Start is
set at 50% and the target frequency, which equals the maximum frequency(m[Hz]ax Freq), is 60Hz, the frequency
which the curve acceleration accounts for when the S-curve accelerates to 30Hz is 0~15Hz and the 15Hz~30Hz
interval is linear acceleration.
ADV-04 Acc S End: You can adjust the slope of the curve when the operating frequency reaches the target
frequency. This is used to set the ratio accounted for by the curve acceleration of the remaining interval on the basis of
the 1/2 frequency of the target frequency as in case of Acc S Start. If set as in Acc S Start above, it accelerates in a
linear slope until 30~45Hz and then accelerates in a curve slope and operates at a steady speed for the remaining
45~60Hz interval.

ADV-05 Dec S Start ~ ADV-06 Dec S End: Sets the curve deceleration slope ratio during deceleration. The setting
method is as the acceleration ratio described above.
S-Curve
Acc/Dec Time in S-curve:
Acc Time = Set Acc Time + Set Acc Time x (ADV-03)/2 + Set Acc Time x (ADV-04)/2
Dec Time = Set Dec Time + Set Dec Time x (ADV-05)/2 + Set Dec Time x (ADV-06)/2
