Instructions for independent move: positioning.

This function has a specific manual. This manual that you are reading now only offers some information
about this function. Refer to the specific documentation to obtain further information regarding the
requirements and operation of the independent axes.
= MOVE ABS
= MOVE ADD
= MOVE INF
Absolute positioning movement (MOV ABS), incremental (MOVE
ADD) or no-end (MOVE INF).
The programming format for each of them is the following.
MOVE ABS (axis, pos, feed, blend)
MOVE ADD (axis, pos, feed, blend)
MOVE INF (axis, direction, feed, blend)
Parameter Meaning
axis Axis to position.
pos Position to reach.
direction Moving direction. It is programmed with parameters "DIRPOS" (positive
direction) or "DIRNEG" (negative direction).
feed Positioning feedrate
blend Dynamic blend with the next block It is programmed using parameters
"PRESENT", "NULL", "NEXT" or "WAITINPOS.
The programming units are the standard PLC units. The coordinates the feedrates will be
given in ten-thousandths if they are in mm or degrees or in hundred-thousandths if they are
in inches.
Position to reach.
With MOVE ABS it will be defined in absolute coordinates whereas with MOVE ADD it will
be defined in incremental coordinates. For positioning, the zero offset active in the channel
is ignored.
The moving direction is determined by the coordinate or the increment programmed. For
rotary axes, the moving direction is determined by the type of axis. If it is unidirectional, it
positions in the preset direction; otherwise, it positions via the shortest path.
Moving direction.
Moving direction. It is used with MOVE INF to execute an endless (infinite) movement until
the axis limit is reached or until the movement is interrupted.
Dynamic blend with the next block
It sets the feedrate used to reach the position (dynamic blend with the next block). It is
programmed with one of the following parameters.
PRESENT The axis reaches the indicated position at the feedrate indicated by the
block itself.
NEXT The axis reaches the indicated position at the feedrate indicated in the
next block.
NULL The axis reaches the indicated position at zero feedrate.
WAITINPOS The axis reaches the indicated position at zero feedrate and it waits
to be in position before executing the next block.
