the spindle speed that is active at the start of the cycle determines the
effective Z feedrate
the direction of spindle rotation for tap-in and tap-out phases will be
automatically generated by the control
spindle speed override has no effect on the solid tapping cycle; you can
use feedrate override to adjust the tapping operation
D cannot exceed the maximum tapping spindle speed set in AMP
you cannot select tools via D-word while in solid tapping mode
gear changes are locked out
cycle stop is acknowledged throughout the cycle, but can be disabled by
G63
you can use active reset to abort the cycle after the cycle stop request
has been acknowledged
to re-tap a hole, a Q-word must have been programmed when the hole
was originally tapped
block retrace is possible during the tap-in portion of the cycle, but not
during the tap-out
