The fundamental unit of positioning is the positioning action. A particular po-
sitioning action moves the workpiece along the axis in a direction, at a speed,
and to a position determined by the data which has been set specifically for
the positioning action. The positioning action begins when the start command
is transferred by the PC program (XSRT, YSRT, or ISRT, depending on
whether you want to position along the X axis, the Y axis, or both simulta-
neously). Before beginning execution of positioning actions, it is necessary to
define the origin as a reference point by, for example, executing origin search
(XORG, YORG, or IORG). The origin is simply the point which is designated
as 0 at any given time. Positioning actions are described in detail in
3-4 Set-
ting Positioning Actions
, using commands to start positioning actions is de-
scribed in
6-5 SRT (Start) Commands and Positioning Actions
, and using
commands with the origin is described in
Section 7 Establishing the Origin
.
