01-23 Switch Frequency between 1st/4th Accel/decel Factory setting: 0
Control
mode VF VFPG FOCPM
Settings 0.00~400.00Hz
This parameter selects the frequency point for transition from acceleration/deceleration time 1
to acceleration/deceleration time 4.
The transition from acceleration/deceleration time 1 to acceleration/deceleration time 4, may
also be enabled by the external terminals. The external terminal has priority over Pr. 01-23.

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 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
Parameter 01-29 is used to set the switch frequency between S4 and S5 for smooth stop.
