Chapter 9 Major Positioning Control
POINT
(1) When the operation pattern is continuous positioning control or continuous
path control, the same address as the last value is specified in absolute
system or the movement amount 0 is specified in incremental system,
positioning control of movement amount 0 is executed.
(2) The BUSY signal turns ON even when position control of movement amount 0
is executed. However, since the ON time is short, the ON status may not be
detected in the PLC program.
(3) The positioning complete signal turns ON even when position control of
movement amount 0 is executed. ON time is determined by "
Pr.40
Positioning
complete signal output time
".
[1] Independent positioning control (Positioning complete)
This control is set when executing only one designated data item of positioning. If
a dwell time is designated, the positioning completes after the designated time
elapses.
This data (operation pattern [00] data) becomes the end of block data when
carrying out block positioning. (The positioning stops after this data is executed.)
