3.2 Smoothing the path velocity

Basic logic functions: Continuouspath Mode, Exact Stop, LookAhead (B1)

Function Manual, 11/2006, 6FC5397-0BP10-2BA0

3.2 Smoothing the path velocity

Several blocks with SOFT and BRISK

Smoothing of the path velocity is only effective in continuouspath mode with LookAhead over

several blocks with SOFT and BRISK, but not with G0.

The cycle times of the control must be parameterized such that the preprocessing is

provided with enough blocks to be able to analyze an acceleration process.
