B–63380EN/02
114
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 option 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.
