Motion buffers

Example of buffered instructions:
BASIC PROGRAM

MOVE(-500)
.......
MOVE(1000)

DATUM(3)

MOVE(200)

BUFFER

MTY PE MOV E(-500)
BUFFER
MOV E -500
BASIC PROGRAM
.......
MOVE(-500)
.......
MOVE(1000)
.......
DATUM(3)

MOVE(200)
.......
DATUM(3)
---------------------------------
NTYPE MOVE(1000)
---------------------------------
MTYPE MOVE(-500)
BUFFER
MOVE -500
2.- A second movement is
loaded while the first one
is not finished.
The new movement waits in the
second buffer.
3.- A third movement can
still be stored in the process buffer.
If the basic program reaches
‘MOVE(200)’ it will wait.
1.- All buffers are empty
and a movement is
loaded. The movement
starts to execute
.
EXAMPLE:
5.- As the sent
movements are finished,
the buffer empties.

6.- If no new movements
are executed, finally, the
buffer will become empty
and the profile generator
becomes inactive.
4.- The first movement has
finished. The buffer moves
by one position .
The next movement starts to
execute.
