For example, for a multistep operation of 2 speeds (500 and 1,500 rpm), if
acceleration time is set to 5 seconds, the operation can be illustrated as shown
in the figure below.
6.5.7.2 S-curve acceleration/deceleration pattern 1–2 (FUN_36–
39)
Acceleration/deceleration gradient level patterns can be configured to enhance
and smooth the inverter’s acceleration and deceleration curves. While linear
pattern features a linear increase or decrease to the output frequency, at a fixed
rate, an S-curve pattern provides a smoother and more gradual increase or
decrease of output frequency, ideal for lift-type loads or elevator doors, etc.
Acceleration/deceleration patterns can be defined by the parameter settings
listed in the following table. Codes FUN_36–FUN_39 define the curvature.
Codes FUN_36 and FUN_37are for acceleration, while FUN_38, FUN_39 are
for deceleration.
