11.1 SPINDLE SPEED FUNCTION (S CODE OUTPUT)
Overview
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.
Signal
Refer to section “Auxiliary Function/Second Auxiliary Function.”

Note
NOTE
1. When a move command and a spindle-speed
function command are specified within the same
block, the commands are executed in either of the
following two ways:
(1) The move command and spindle-speed function
are started at the same time.
(2) After the move command is completed, the
spindle-speed function command is started.
Whether (1) or (2) takes place depends on the
processing on the PMC side.
2. For S code output when spindle serial output or
spindle analog output is used, see Section 9.3,
"SPINDLE SPEED CONTROL".
