The sharp of S-curve was decided by P1.08~P1.13, the quality of S-curve can directly
affect the comfortable feeling of elevator’s start and stop. The parameters of S-curve
were comprised of start quadric acceleration (P1.08), start acceleration (P1.09),
speed-down quadric deceleration (P1.10), deceleration (P1.11), stop quadric
deceleration (P1.12), stop deceleration (P1.13), start speed (P1.14) and start holding
time (P1.15). The correspondence relation of the parameters and S-curve is as follow:

Figure 6.4 S - curve setting sketch map description.
The above diagram is the sketch map of setting s-curve of accelerated portion, the
s-curve steepens as the parameter was increased, and the s-curve slackens as the
parameter was decreased. S-curve adjustment principle of deceleration segment and
stop segment is the same with principle of acceleration.
