S curve selection
The S-curve feature allows the machine to be smoothly started and stopped, reducing the impact on the load.
Set the S-curve characteristic time at the start of acceleration/deceleration and at the end of acceleration/deceleration as needed.
This function is enabled by F01.30=1[S Curve Selection=Enabled].
The S curve characteristics when running switching (forward/reverse) are as shown in the figure below.

Schematic diagram of S curve
Note:
After setting the S-curve characteristic, the acceleration/deceleration time will increase the acceleration/deceleration time as shown below.
Acceleration time = selected acceleration time + ([F01.31]+[F01.32])/2
Deceleration time = selected deceleration time + ([F01.33]+[F01.34])/2
