[Pr.32] JOG operation acceleration time selection
Set which of "acceleration time 0 to 3" to use for the acceleration time during JOG operation.
0: Use value set in "[Pr.9] Acceleration time 0".
1: Use value set in "[Pr.25] Acceleration time 1".
2: Use value set in "[Pr.26] Acceleration time 2".
3: Use value set in "[Pr.27] Acceleration time 3".
[Pr.33] JOG operation deceleration time selection
Set which of "deceleration time 0 to 3" to use for the deceleration time during JOG operation.
0: Use value set in "[Pr.10] Deceleration time 0".
1: Use value set in "[Pr.28] Deceleration time 1".
2: Use value set in "[Pr.29] Deceleration time 2".
3: Use value set in "[Pr.30] Deceleration time 3".
[Pr.34] Acceleration/deceleration process selection
Set whether to use trapezoid acceleration/deceleration or S-curve acceleration/deceleration for the acceleration/deceleration
process.

[Pr.35] S-curve ratio
Set the S-curve ratio (1 to 100%) for carrying out the S-curve acceleration/deceleration process.
The S-curve ratio indicates where to draw the acceleration/deceleration curve using the Sin curve as shown below.
Velocity
Time
The acceleration and deceleration
are linear.
