Description:
Number of memory elements available for limiting the path velocity and chang-
ing it in the block.
0 : Each block is limited by a maximum path velocity.
> 0 : If required, a profile of the permissible path velocity
; and its modification options is generated and monitored
; in the block.
; This results in a smoother axis velocity progression and
; a shorter travel time.
; MD28530 $MC_MM_PATH_VELO_SEGMENTS defines the average
; number of segments available in the block.
; The necessary setting essentially depends
; on the requirements.
The following values are recommended:
3: for G643 and G644, if only geometry axes are traversed
5: for G643 and G644, if geometry and rotary axes are traversed
5: for COMPCAD
5: for dyn. transformation
A value that is too low this may lead to additional velocity limitations if a
sufficient number of blocks cannot be made available for interpolation.
MD28530 $MC_MM_PATH_VELO_SEGMENTS additionally increases the memory require-
ment of dyn. Look Ahead. Values higher than 5 are only practical in excep-
tional cases.
3 ... 5 :
Recommended setting.
