Description:
Number of memory elements available for limiting the path velocity and changing it in
the block.
0
> 0 : If required, a profile of the permissible path velocity
The following values are recommended:
3:
5:
5:
5:
8:
A value that is too low 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 requirement of
dyn. Look Ahead. Values higher than 8 are only practical in exceptional cases.
3 ... 8 :

Description:
The machine data is used to configure the work memory for extended LookAhead.
The MD scales the value defined internally through MD28060 $MC_MM_IPO_BUFFER_SIZE,
MD28520 $MC_MM_MAX_AXISPOLY_PER_BLOCK, MD28530 $MC_MM_PATH_VELO_SEGMENTS, MD28535
$MC_MM_FEED_PROFILE_SEGMENTS, MD28540 $MC_MM_ARCLENGTH_SEGMENTS).
Its practical size depends on the part program, the block lengths, the axis dynamics,
and an active kinematic transformation.

: Each block is limited by a maximum 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.
