The
Linear acceleration/deceleration curve
when
P.29=0:
The acceleration slope is constructed by combining
P.7
and
P.20
. The deceleration slope is
constructed by combining
P.8
and P.20.
The target frequency increases and decreases linearly as the acceleration and the deceleration slopes
presented in the figure below.
•
S-shape acceleration/deceleration curve 1
when
P.29=1:
The acceleration slope is formed by combining P.7 and
P3
. The deceleration slope is formed by
combining P.8 and P.3.
The acceleration and deceleration curves are in an S-shape.
The equation for the ascending S-shape curve between 0 and Pr3 is:
The equation for the ascending S-shape curve above Pr3 is:
