NOTE
1 Since data values of X (U), Z (W) and R during canned cycle are
modal, if X (U), Z (W), or R is not newly commanded, the previously
specified data is effective. Thus, when the Z axis movement
amount does not vary as in the example below, a canned cycle can
be repeated only by specifying the movement commands for the
X–axis.
However, these data are cleared, if a one–shot G code expect for
G04 (dwell) or a G code in the group 01 except for G90, G92, G94
is commanded.
The cycle in the above figure is executed by the following program.
N030 G90 U–8.0 W–66.0 F0.4 ;
N031 U–16.0 ;
N032 U–24.0 ;
N033 U–32.0 ;
2 The following three applications can be performed.
(1) If an EOB or zero movement commands are specified for the
block following that specified with a canned cycle, the same
canned cycle is repeated.
(2) By specifying a canned cycle in the MDI mode, and pushing the
cycle start button after the block terminates, the same canned
cycle as the previous one will be performed.
(3) If the M, S, T function is commanded during the canned cycle
mode, both the canned cycle and M, S, or T function can be
performed simultaneously. If this is inconvenient, cancel the
canned cycle once as in the program examples below (specify
G00 or G01) and execute the M, S, or T command. After the
execution of M, S, or T terminates, command the canned cycle
again.
