Function
G84 and G74 for mill control types.
G84 and G84.1 for lathe control types.
This parameter determines whether the control allows a dwell at hole
bottom during the execution of either the tapping cycle or left hand tapping
cycle. Dwells are normally programmed in the cycle block with a P-word
and may be in either seconds or spindle revolutions.
YES -- Setting a value of “YES” for this parameter causes the control to
ignore any P-word that is programmed for a dwell in a tapping or left hand
tapping cycle block. No dwell is permitted during the actual tapping
operation; however, dwells may still be programmed using a G04 code if
desired.
NO -- Setting a value of “NO” for this parameter allows the control to
recognize any P-word that is programmed for a dwell in a tapping or left
hand tapping cycle block.

(b) No
Notes
This is a global parameter; the value set here applies to all axes
and processes.
This parameter does not affect normal dwells that are programmed with a
G04. Only dwells that are programmed in a milling or drilling cycle are
affected.
