11.SPINDLE SPEED FUNCTION B-63943EN-1/02
- 1396 -
NOTE
3 Similarly, when multiple signals from RGTSP1 to
RGTSP4 are set to 1 simultaneously, the signals
are checked in the order from RGTSP1 to RGTSP2
to RGTSP3 to RGTSP4, and the spindle
corresponding to the signal that is first found to be
set to 1 is assumed to be specified.
Spindle-by-spindle stop signals *SSTP1<Gn027#3>,*SSTP2<Gn027#4>,*SSTP3<Gn027#5>,
*SSTP4<Gn026#6>
[Classification] Input signal
[Operation] These signals are used to stop each spindle when the multi-spindle
control option is used. In a PMC sequence for rigid tapping, the ENB
and ENB2 signals are used. Accordingly, the logic of the signals used
for a spindle selected to perform rigid tapping must match the logic of
the spindle stop signal *SSTP.
*SSTP1 1 : The output to the first spindle is not forced to 0 min
-1
.
0 : 0 min
-1
is commanded to first spindle.
*SSTP2 1 : The output to the second spindle is not forced to 0 min
-1
.
0 : 0 min
-1
is commanded to second spindle.
*SSTP3 1 : The output to the third spindle is not forced to 0 min
-1
.
0 : 0 min
-1
is commanded to third spindle.
*SSTP4 1 : The output to the fourth spindle is not forced to 0 min
-1
.
0 : 0 min
-1
is commanded to fourth spindle.
Position coder selection signal PC2SLC<Gn028#7>,PC3SLC<Gn026#0>,PC4SLC<Gn026#1>
[Classification] Input signal
[Operation] This signal is used to select the position coder when the multi-spindle
control option is being used. Note, however, that it cannot be used
with a spindle selected to perform rigid tapping.
For rigid tapping, this signal is not used. Instead, a position loop is
constructed by combining the first spindle with the first position coder,
by combining the second spindle with the second position coder, by
combining the third spindle with the third position coder, or by
combining the fourth spindle with the fourth position coder.
However, the display of the actual speed is switched by this signal,
even during rigid tapping.
