Relative Positioning without Residual Path Storage
• P-0-4019, Positioning block mode = 2h
In the case of relative positioning blocks without residual path storage, the
target position contained in the positioning block is added to the current
position.
Relative positioning blocks are also executed, if the drive has not been
homed.
By sequencing relative positioning blocks it is possible to position with
incremental dimension. If a relative positioning block without residual path
storage is interrupted, the incremental dimension reference gets lost.
If the positioning block is completed (i.e. the drive reaches target position
and message "end position reached" is active), positioning is possible
without losing the incremental dimension reference.
Note: If infinite positioning in either a forward or backward direction
is achieved by sequencing relative positioning blocks
(transport belt), the position data must be scaled in modulo
format (modulo value = length of transport belt or modulo
value = 2*maximum travel distance).
