Acceleration And Jerk - Siemens SINUMERIK 828D Function Manual

Acceleration profile: SOFT
1: Jerk according to $MA_MAX_AX_JERK[..]
2: Jerk according to $AC_PATHJERK
3: Jerk according to $MA_MAX_AX_JERK[..] (approach block end velocity)
4: Velocity limit due to arc
5: Jerk according to $AC_PATHJERK

Acceleration and jerk

Key statement
In the following example a short part program is used to illustrate the velocity and acceleration characteristic for
the X-axis. It also shows the connection between specific velocity and acceleration-related machine data and the
contour sections they influence.
