Acceleration and deceleration
S-pattern acceleration/deceleration C (Pr. 29 = 4, Pr. 380 to Pr. 383)
With the S-pattern acceleration/deceleration C switch signal (X20), an acceleration/decelera-
tion curve S-pattern 1 or S-pattern 2 can be selected. For the terminal used for X20 signal input,
set "20" in any of Pr. 178 to Pr. 189 (input terminal function selection) to assign the function.

Tab. 6-41: Selection of acceleration/deceleration curve S-pattern 1 or S-pattern 2
Set % of time taken for forming an S-pattern in Pr. 380 to Pr.383 as acceleration time is 100%.
