Adjusting The S Curve For Normal Running - INVT Goodrive390L Series User Manual

Goodrive390L Series Lift-Dedicated VFD
or set P00.13=1.
Note: For SMs, swapping the motor cables requires the motor parameter autotuning
(pole angle) again. It is recommended to set P00.13 to change the running direction of
the lift.

6.4.3 Adjusting the S curve for normal running

Before normal running, check that the control logic is correct and wiring is correct. After
these are confirmed to be correct, adjust the S curve. For details, see the descriptions of
P10.38–P10.45.

P10.38–P10.45 determine the shape of S curve. The S-curve quality directly impacts the
comfortability of the lift at startup or stop. The S-cure parameters are listed in the above
table. The following figure describes the relationship between these parameters and
S-curve.
