(*1) This signal is effective when parameter 0031#5=0 in the T
series
(*2) This signal is effective when parameter 0031#5=1 in the T
series
This signal is also effective when M series with the
surface speed constant control option.
(*3) This signal is effective when parameter 0019#4=0
(This signal is always effective only for T/TT series.)
(*4) This signal is effective when parameter 0019#4=1
(This signal is ineffective for T/TT series.)
(*5) The rigid tapping of the second spindle is available by the
multi-spindle control function.
When SWS1 is set to 1 (regardless of whether SWS2 is set to
0 or 1), rigid tapping is performed using the 1st spindle.
When SWS1 is set to 0, and SWS2 is set to 1, rigid tapping
is performed using the 2nd spindle.
(*6) This signal is used when the rigid tapping of the second
spindle.
According to the GR21 signal, the individual gear parameters
for gear 1 or 2, also used for the 1st spindle, are selected.
