For Series 15–T, G83 or G83.1 does not cause the tool to dwell. For the
FS15 tape format, the tool dwells at the bottom of the hole only if the
block contains a P address.
In Series 15–T, G84/G84.2 causes the tool to dwell before the spindle
starts rotating in either the normal or reverse direction, according to the
corresponding parameter setting. For the FS15 tape format, when the
block contains a P address, the tool dwells at the bottom of the hole and
at the R position before the spindle starts rotating either in the normal or
reverse direction.
For the FS15 tape format, rigid tapping can be specified by using the
methods listed below:
Format Condition (parameter), comment
G84.2 X_ Z_ R_ ...S**** ;
S**** ;
G84.2 X_ Z_ R_ .... ;
Setting (F10/F11) = 1
M29 S**** ;
G84 X_ Z_ R_ .... ;
* Common to Series 16 format
M29 S**** G84 X_ Z_ R_ .... ;
G84 X_ Z_ R_ .... S**** ;
G84 is made a G code for rigid tapping.

Bit 0 (G84) of parameter No. 5200 = 1
* Common to Series 16 format
Specifying 1 for bit 7 (RDI) of parameter No. 5102 causes the canned
cycle R command diameter or radius programming mode in the FS15 tape
format to match the diameter or radius programming mode for the drilling
axis.
Specifying bit 3 (F16) of parameter No. 5102 disables the FS15 tape
format. This applies only to the canned drilling cycle. However, the
number of repetitions must be specified by using the L address.
CAUTION
Setting bit 3 (F16) of parameter No. 5102 to 1 overrides bits
6 (RAB) and 7 (RDI) of parameter No. 5102; both settings
are assumed to be 0.
It is impossible to use the C–axis (the third axis) as a drilling axis. So,
specifying G18 (ZX plane) generates P/S alarm No. 28 (plane selection
command error).
For the FS15 tape format, it is impossible to specify an M code for
clamping the C–axis.
