determine the S-curve shape. The S-curve quality directly impacts the comfortability
of the lift at startup or stop. The S-curve parameters are listed in the table above. Figure 7-5 describes
the relationship between these parameters and S-curve.

Figure 7-6 S-curve adjusting
Figure 7-6 describes the ACC segment S-curve parameter adjustment, in which the S curve changes
sharply when the time decreases but the S curve changes slightly when the time increases. The
adjustment principle of the DEC segment S-curve parameters and stop segment S-curve parameters
are similar to that for the ACC segment S-curve parameters.
indicates the initial frequency during inverter startup. During inverter running, if the set speed
(frequency) is less than the starting frequency of startup, the inverter output frequency is 0. Only
when the set speed (frequency) is greater than or equal to the starting frequency, the inverter starts at
the starting frequency and runs according to the S curve. Setting a proper starting frequency can
reduce startup impact by overcoming the static friction during startup.

are key S-curve parameters, impacting passenger comfortability during ACC,
DEC, and stop.
7.4.4 Adjusting comfortability during startup or stop
Startup comfortability can be adjusted by setting the following function codes:
. If the analog weighing equipment is used, startup
pre-torque compensation must be adjusted. For details, see the descriptions of the function codes.
Stop comfortability can be adjusted by setting the following function codes:
7.4.5 Adjusting lift leveling accuracy
If floors are different in the leveling error, adjust each position of flashboard to keep the same errors
