S-curve T4 Time
The S-curve can smooth the vibration of machine at the period of motor’s speed change. To
set the s-curve time longer can get more effect of smoothing, but it causes timing extends for
actual acc. time and deceleration time.

Example: Explain how the S-curve affects the Acc. and Dec. timing.

If setting Pr.053 (Acc. Time) =1.00 (Sec/Krpm), and Pr.055 (S-curve T1 Time) = 1.00sec, Pr.056
(S-curve T2 Time) = 1.00sec.
Ta (totally acc. time) = (0.5 x S-curve T1 Time) + (Acc. Time) + (0.5 x S-curveT2 Time) = 2sec.
