Chapter 2: Commands Calling Axis Movements
(1) Intermediate Positioning Point
•
It is not possible to specify the intermediate positioning point in the G29 block. The
axes return to the previous point at a rapid traverse rate along the paths taken in the
return to the reference point. Note that the axes not specified in the G29 block do not
move.
•
If G28 or G30 (see 2.2.4, “Second to Fourth Reference Point Return (G30)”) has been
executed several times before the execution of GJ29, point B to be set for the execu-
tion of B29 is established at the intermediate positioning point set in the last G28 or
G30 operation. The following program written in absolute commands explains how
point B is set for the return operation from the reference point.
