GTT Selection of a spindle gear selection method
0 : Type M.
1 : Type T.
NOTE
1 Type M:
The gear selection signal is not entered. In response to an
S command, the CNC selects a gear according to the speed
range of each gear specified beforehand in parameters.
Then the CNC reports the selection of a gear by outputting
the gear selection signal. The spindle speed corresponding
to the gear selected by the gear selection signal is output.
Type T:
The gear selection signal is entered. The spindle
speed corresponding to the gear selected by this signal is
output.
2 When the constant surface speed control is selected, type
T is selected, regardless of whether this parameter is
specified.
3 When type T spindle gear switching is selected, the
following parameters have no effect:
No. 3705#2 SGB, No. 3751, No. 3752, No. 3705#3 SGT,
No. 3761, No. 3762, No. 3705#6 SFA, No. 3735, No. 3736
However, parameter No. 3744 is valid.
