9. SPINDLE SPEED FUNCTION
438
During spindle synchronization or simplified synchronization control,
the second spindle operates in phase with the first spindle. Multi-spindle
control for the first spindle can be used during synchronization control,
but multi-spindle control for the second spindle is disabled.
Using the spindle selection signal (SWS 1–2), rigid tapping can use either
the first or second spindle as the rigid tap spindle. There are certain
restrictions:
D Set the SWS 1 to 2 signals before directing rigid tapping;
D Do not switch the SWS 1 to 2 signals during rigid tapping; and
D Use the appropriate ENB signal (either ENB or ENB2) for the selected
spindle as the ENB signal for the rigid tapping PMC sequence.
The spindles not used for rigid tapping can be rotated at a speed specified
before rigid tapping starts, or can be stopped.
[Classification] Input signal
[Function] Controls whether S command specified to the NC is output to the spindle
or not in multi-spindle.
SWS1 1 : Outputs a speed command to the first spindle.
0 : Outputs no speed command to the first spindle.
SWS2 1 : Outputs a speed command to the second spindle.
0 : Outputs no speed command to the second spindle.
[Classification] Input signal
[Function] Effective only to multi-spindle, each spindle can be stopped by this signal.
*SSTP1 1 : Does not set 0 min
–1
for output to the first spindle.
0 : Sets 0 min
–1
for output to the first spindle.
*SSTP2 1 : Does not set 0 min
–1
for output to the second spindle.
0 : Sets 0 min
–1
for output to the second spindle.
