Default:
0.00
Settings
0.00–400.00 Hz
Determines the frequency for the transition from acceleration and deceleration time 1 to acceleration and
deceleration time 4. You can also enable the transition from acceleration or deceleration time 1 to
acceleration and deceleration time 4 with the external terminals (Pr.02-01–Pr.02-08). The external terminal
has priority over Pr.01-23.

Using an S-curve gives the smoothest transition between speed changes. The acceleration and
deceleration curve adjusts the acceleration and deceleration S-curve. When enabled, the motor drive
produces a different acceleration and deceleration curve according to the acceleration and deceleration
time.
The Actual Acceleration Time = selected acceleration Time + (Pr.01-24 + Pr.01-25)
÷
2.
The Actual Deceleration Time = selected deceleration Time + (Pr.01-26 + Pr.01-27 + Pr.01-30 x 2)
÷
2.
Use Pr.01-29 to set the switch frequency between S4 and S5 for smooth stopping.
Set Pr.01-29 to the leveling speed of the elevator.
