SPINDLE COMMAND
—
ROTATION SPEED INPUT
[Function]
This signal informs the value of S function (S) data specified in automatic operation (memory or MDI)
or by manual numerical data input. "Spindle command rotation speed" output from the controller is
binary data. The data can be monitored in the "S display" on the command value screen. (For type A,
the "S display" displays the contents of file registers R212 and R213.)
[Operation]
Set "Spindle command rotation speed input" is renewed when:
(1) "S**" is specified in automatic operation (memory or MDI) and "M function finish 1 or 2" signal
(FIN1 or FIN2) or "Gear shift complete" signal (GFIN) is sent back to the controller.
(2) "S**" is specified by manual numerical command input and "M function finish 1 or 2" signal
(FIN1 or FIN2) or "Gear shift complete" signal (GFIN) is sent back to the controller.
(Note 1) Data cannot be cleared by "reset" or "emergency stop".
<Data flow>
S function
command
S function strobe 1 (SF1) turns on
and the following signals rise:
M func. complete 1, 2 (FIN1, FIN2)
Gear shift complete (GFIN)
Reset & rewind (RRW)
or during synchronous tapping
When the system is under constant surface speed control, constant
surface speed data is set for "Spindle command rotation speed input".
(Note 2) "Spindle command rotation speed input" directly denotes spindle speed (r/min) specified
as S function command.
