Chapter 4 Parameters|
4-36 Revision August 2008, 2ELE, V1.02
01.17 Acceleration S-Curve Unit: 0.1/0.01
01.18 Deceleration S-Curve Unit: 0.1/0.01
Factory Setting: 0
Settings 0.0 S-curve disabled
0.1 to 10.0/0.01 to 10.00 S-curve enabled (10.0/10.00 is the smoothest)
This parameter is used to ensure smooth acceleration and deceleration via S-curve.
The S-curve is disabled when set to 0.0 and enabled when set to 0.1 to 10.0/0.01 to 10.00.
Setting 0.1/0.01 gives the quickest and setting 10.0/10.00 the longest and smoothest S-curve.
The AC motor drive will not follow the Accel/Decel Times in Pr.01.09 to Pr.01.12.
The diagram below shows that the original setting of the Accel/Decel Time is only for reference
when the S-curve is enabled. The actual Accel/Decel Time depends on the selected S-curve
(0.1 to 10.0).
The total Accel. Time=Pr.01.09 + Pr.01.17 or Pr.01.11 + Pr.01.17
The total Decel. Time=Pr.01.10 + Pr.01.18 or Pr.01.12 + Pr.01.18
