BufferMode Description of Operation
5
：
mcBlendingHigh
(High velocity)
The buffered instruction is executed after the target position of the current
instruction is reached. The transit velocity is set to the target velocity of the
current instructionor the buffered instruction, whichever is highest.

Example: Brefly explain with two MoveRelative instructons
The max velocity and the displacement of the first and second instruction are respectively
V
1
,
S
1
and
V
2
,
S
2.
Different types of BufferModes set for the second instruction result in various transitting situation shown as
follows.

Buffermode=mcAborting
1.
Present instruction aborted during acceleration.
2.
Present instruction aborted at constant speed.
3.
Present instruction aborted during decelerating.
4.
The instruction transferred and the present
instruction are in opposite direction.
