Note
Ifthevalue0issetinto
_ZSFR[1], 1 mm or 1 inch is used for the retraction distance as
default.
If it is need to specify 0 mm or 0 inch, set a smaller value than the movable resolution.
Peck tapping cycle
Rapid traverse is performed to R level after positioning along the X and Y axes.
Cutting is performed from point R with depth Q (depth of cut for each cutting feed).
Subsequently a return is carried out to point R. Whether retraction is overridden or
not is specified by a value other than 100% set to GUD7 _ZSFI[2]. Moving the cut-
ting feedrate F is carried out from point R to a position distance d from the end
point of the last cutting. This is where the cutting is restarted.
The spindle is stopped once point Z is reached, and, subsequently, rotated in the
reverse direction for retraction.
Set d (distance to the point where the cutting is started) in GUD7 _ZSFR[1].

Axis switching
The canned cycle must be canceled before the drilling axis c an be changed. An
alarm is issued whenever the drilling axis is changed in rigid mode.
S command
An alarm is issued whenever a speed higher than the maximum speed for the gear
in use is specified.
F command
An alarm is issued, if a value overshooting the upper limit of the cutting feedrate is
specified.
