1 After a reset has been performed, setting the tap return signal (RTNT)
to 1 in the MDI mode causes M05 to be output.
Do not attempt to perform gear shift and orientation during a tap
return.
2 After the spindle has stopped, returning FIN causes M03 (M04) and
the same S command as for when tapping is discontinued to be output.
3 Once the spindle has started, returning FIN triggers tap returning.
4 After tap returning is completed, M05 and S0 are output, and the tap
return completion signal (RTPT) becomes 1.
5 Returning FIN triggers a reset.
NOTE
If bit 6 (SFA) of parameter No. 3705 is 0, SF will not be output
unless a gear shift occurs.
