cutting feed and before 1
st
feed (traverse instruction) block is
distributed and when the feed block is read and its time is set by the
parameter No. 72.
2. After the S code is commanded and before the 1
st
feed block is
distributed, CNC check wait time is the same that of the above.
3. When S code and the feed traverse during the same block are
commanded, CNC detects SAR signal during the feed fixed time.
When SAR signal is 1, the feed starts.
Signal address
9.3 Constant surface speed control
General
With the spindle serial output or analog output function, specifying the surface speed
(m/mduring or feet/min) directly during an S instruction makes it possible to change
the spindle output continuously so as to maintaduring a constant surface speed at a
programmed point. (For the rapid traverse instruction, however, the surface speed for
the end point is output at the beginning of rapid traverse.)
Whether or not constant surface speed control is performed is selected by G code.
G96: execute the constant surface speed control, S is m/mduring or feet/mduring
during G96.
G97: do not execute the constant surface speed control, S is r/mduring during G97.
