Whether retraction is overridden ornot 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 endpoint of the last cutting. This is where the cutting is restarted.The spindle is stopped once point Z is reached, and, subsequently, rotated in thereverse direction for retraction.Set d (distance to the point where the cutting is started) in GUD7 _ZSFR[1].NoteI fthe value 0 is set into _ZSFR[1], 1 mm or 1 inch is used for the retraction distance asdefault.If it is need to specify 0 mm or 0 inch, set a smaller value than the movable resolution.Axis switchingThe canned cycle must be canceled before the drilling axis can be changed. Analarm is issued whenever the drilling axis is changed in rigid mode.S commandAn alarm is issued whenever a speed higher than the maximum speed for the gearin use is specified.F commandAn alarm is issued, if a value overshooting the upper limit of the cutting feedrate isspecified.
