Factory Setting: 00
Settings 00 Linear acceleration / deceleration
01 Auto acceleration, linear Deceleration.
02 Linear acceleration, auto Deceleration.
03 Auto acceleration / deceleration
04 Auto acceleration / deceleration (refer to Accel/Decel Time
setting)
If this parameter is set to 03, the AC drive will accel/decel in the fastest and smoothest
means possible by automatically adjusting the time of accel/decel.
If this parameter is set to 04, the real accel/decel time will be equal to or more than
parameter Pr.01-09 ~Pr.01-12 and Pr.01-18 to Pr.01-21.

Deceleration S-Curve Factory Setting: 00
Settings 00 to 07
This parameter is used to ensure a smooth acceleration and deceleration. The S-curve
is enabled when sets at 01-07. Setting 1 offers the quickest S-curve and 07 offers the
longest and smoothest S-curve. The AC drive will not follow Accel/Decel Time in
Pr.01-09 to Pr.01-12. To Disable the S-curve, set Pr.01-16 and Pr.01-17 to 00.
NOTE: 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 (01 to 07).
