◆ C2: S-Curve Characteristics
Use S-curve characteristics to smooth acceleration and deceleration and to minimize abrupt shock to the load.
Set S-curve characteristic time during acceleration/deceleration at start and acceleration/deceleration at stop.
The following figure explains how S-curves are applied.
