(1) Canned Cycle Output Signal (G80S)
When a canned cycle is started, the canned cycle output signal (G80S) is ouput within 8
msec after the start of the canned cycle. The canned cycle (G80S) is “opened” at the
canned cycle cancel block.
Fig. 7.1 Canned Cycle Output Signal (G80S)
(2) Tapping Cycle Signal (G84S)
When a tapping cycle (G74,G84) is started, the tapping cycle output signal (G84S) is
output within 8 msec after the start of the tapping cycle. The tapping cycle output signal
(G84S) is “closed” at the tapping cycle cancel block.
Fig. 7.2 Tapping Cycle Output Signal (G84S)
(3) Tapping Output Signal (TAP)
This output signal indicates that the CNC is executing tapping during the execution of a
part program in automatic operation.
The tapping output signal is output within 8 msec after the start of cutting from R-point
level to Z-point level. The signal is “opened” at the completion of cutting from Z-point
level to R-point level.
