- 1239 -
NOTE
1 M type
The gear selection signal is not input. The CNC
selects a gear based on the speed range of each
gear set by a parameter beforehand according to S
codes, and the selected gear is posted by
outputting the gear selection signal. Moreover,
the spindle speed matching the gear selected by
the output gear selection signal is output.
T type
The gear selection signal is input. The spindle
speed matching 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#1(GST), No.3705#3(SGT), No.3761,
No.3762, No.3705#6(SFA), No.3735, No.3736
On the other hand, parameter No. 3744 becomes
usable.
