9. SPINDLE SPEED FUNCTION
502
When up to five digits are specified after address S, code and strobe
signals are sent out and used to control the spindle speed. The code
signals are retained until another S code is issued.
One S code is used for each block. Parameter No. 3031 can be used to
specify the maximum number of digits. If a number greater than the
maximum number is specified, an alarm can be raised.
Refer to section 8.1.
3031 Allowable number of digits for the S code
[Data type] Byte
[Valid data range] 1 to 5
Set the allowable numbers of digits for the S codes.
NOTE
1 When a move command and miscellaneous function are
specified in the same block, the commands are executed in
one of the following two ways:
i) Simultaneous execution of the move command and
miscellaneous function commands.
ii) Executing miscellaneous function commands upon
completion of move command execution.
The selection of either sequence depends on the PMC
processing sequence.
2 For S code output when the spindle serial output/spindle
analog output is used, refer to section 9.3.
