Adjusting Comfortability During Startup Or Stop; Adjusting Lift Leveling Accuracy - INVT Goodrive390L Series User Manual

The above figure describes the S-curve parameter adjustment during the acceleration
segment, in which the S curve changes sharply when the time parameter decreases while
the S curve changes slightly when the time parameter increases. The S-curve parameter
adjustment principle during the DEC segment and stop segment are similar to that
during the ACC segment.
P01.03 indicates the initial speed during VFD startup. During VFD running, if the set speed
is less than the starting speed of startup, the VFD output speed is 0. Only when the set
speed is greater than or equal to the starting speed, the VFD starts at the starting speed
and runs according to the S curve. Setting a proper starting speed can reduce startup
impact by overcoming the static friction during startup.
P01.03 indicates the duration that the VFD run at the starting speed at startup.
Note: P10.38–P10.45 are the key S-curve parameters, impacting passenger
comfortability during ACC, DEC, and stop.

6.4.4 Adjusting comfortability during startup or stop

Startup comfortability can be adjusted by setting the following function codes: P01.01,
P01.03, P10.38, P10.39, P10.40, P03.00, P03.01, and P96.18. 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: P10.44,
P10.45, P10.53, P03.00, P03.01, and P96.17.

6.4.5 Adjusting lift leveling accuracy

When the leveling error of each floor is different, adjust the position of the leveling board
for each floor to ensure that the leveling error of each floor is the same. When the leveling
error of each floor is the same, adjust the lift creeping speed (set by multiple speeds) and
P10.44, P10.45, and P10.53.
