4–10 Manual Operations
Although positioning is generally carried out according to the program in the
memory of the PC, the Position Control Unit also allows you to position man-
ually when you need to. You can choose from three manual feeding com-
mands, depending on how far and how fast you wish to change the position.
These three, HIGH-SPEED JOG, LOW-SPEED JOG, and INCH, are ex-
ecuted when their respective command bits turn ON in the IR area. As with
other commands, the Position Control Unit makes use of the DM area data in
carrying them out. You can use HIGH-SPEED JOG or LOW-SPEED JOG for
rapid manual positioning. HIGH-SPEED JOG uses acceleration and deceler-
ation as well as the target speed. You can use INCH for very fine adjust-
ments, feeding one pulse at a time.
4–10–1 DM Area Settings
In addition to the settings described in this section, the following data must
also be set in order to execute HIGH-SPEED JOG. They are the same as
those set for START, so they can be set by following the instructions con-
tained in
Section 4–1. Only the first three of these need be set for
LOW-SPEED JOG.
