 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 accel./decel. time is set to 0.
 When Pr.01-12, 01-14, 01-16, 01-18  Pr.01-24 and Pr.01-25,
The Actual Accel. Time = Pr.01-12, 01-14, 01-16, 01-18 + (Pr.01-24 + Pr.01-25)/2
 When Pr.01-13, 01-15, 01-17, 01-19  Pr.01-26 and Pr.01-27,
The Actual Decel. Time = Pr.01-13, 01-15, 01-17, 01-19 + (Pr.01-26 + Pr.01-27)/2

 These parameters are used to set the skip frequency of the AC drive. But the frequency output is
continuous. There is no limit for the setting of these six parameters and can be used as required.
 The skip frequencies are useful when a motor has vibration at a specific frequency bandwidth. By
skipping this frequency, the vibration will be avoided. It offers 3 zones for use.
 These parameters are used to set the skip frequency of the AC drive. But the frequency output is
continuous. The limit of these six parameters is 01-28≥01-29≥01-30≥01-31≥01-32≥01-33. This
function will be invalid when setting to 0.0.
 The setting of frequency command (F) can be set within the range of skip frequencies. In this
moment, the output frequency (H) will be limited by these settings.
 When accelerating/decelerating, the output frequency will still pass the range of skip frequencies.
