9. SPINDLE SPEED FUNCTION
1125
CAUTION
1 If the primary spindle stop signal *SSTP for stopping all
selected (SWS1 to SWS4) spindles’ rotation is cleared, the
speed command is restored. A spindle not selected by
SWS1 to SWS4 and rotating at its previous speed, which is
stopped using its respective command *SSTP1 to *SSTP4,
cannot be restored to that speed when the signal is cleared.
2 Type A multi-spindle control differs from Type B in the
relationship between the SWS1 and SIND signals for the
first spindle. In Type B, SIND functions only when SWS1 is
set to “1”. In Type A, SIND functions whether SWS1 is “1”
or “0”; each spindle is selected by either of its respective
SWS1 or SIND signals being set to “1”.
NOTE
1 The spindle orientation signal, spindle speed override
signals, and spindle stop signal *SSTP function only for the
selected spindles (corresponding to which spindle selection
signals (SWS1 to SWS4) are set to 1).
2 The S 12-bit code signals R01O to R12O outputs the state
of a selected spindle. If two or more spindles are selected
at the same time, the states of the first, second, third, and
fourth spindles are output in this order.
3 The multi-spindle function allows four position coder
interfaces to be used. But the number of actual speed
indications on the CNC screen does not change. The speed
based on the feedback information of the selected position
coder is displayed.
4 An SOR command has priority over S commands and
SIND-based rotation control from the PMC, and will cause
all selected spindles to perform orientation rotation.
