Chapter 4: AC Drive Parameters
4–20
Decel S-Curve Default Setting: 00
Range: 00 to 07
This parameter is used whenever the motor and load need to be decelerated more
smoothly. The Decel S-Curve may be set from 00 to 07 to select the desired
deceleration S-Curve.
Acceleration Time 2
Default Setting: 10.0
Range: 0.1 to 600 sec
The Second Acceleration Time determines the time for the AC drive to accelerate
from 0 RPM to Maximum Motor RPM (P0.04). Acceleration Time 2 (P1.05) can
be selected using a multi-function input terminal or frequency transition (P1.07).
Deceleration Time 2
Default Setting: 30 sec
Range: 0.1 to 600 sec
The Second Deceleration Time determines the time for the AC drive to decelerate
from Maximum Motor RPM (P0.04) to 0 RPM. Deceleration Time 2 (P1.06) can
be selected using a multi-function input terminal or frequency transition (P1.07).

From the diagram shown below, the original setting accel/decel time will be for
reference when the function of the S-curve is enabled. The actual accel/decel time will
be determined based on the S-curve selected (1 to 7).
