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.
Part program
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
