S-curve for Deceleration Arrival Time 2

Control
VF VFPG
mode
Settings
It is used to give the smoothest transition between speed changes. The accel./decel. curve
can adjust the S-curve of the accel./decel. When it is enabled, the drive will have different
accel./decel. curve by the accel./decel. time.
The S-curve function is disabled when Pr.00-13 is set to 0.
The Actual Accel. Time = selected accel. Time + (Pr.01-24 + Pr.01-25)/2
The Actual Decel. Time = selected decel. Time + (Pr.01-26 + Pr.01-27)/2

These parameters are used to set the skip frequency of the AC drive. The skip frequencies are
useful when a motor has vibration at a specific frequency bandwidth. By skipping this
frequency, the vibration will be avoided.
