Signal
Spindle speed command signal RO0A-RO15A<F010,F011>:For 1st spindle
RO0B-RO15B<F320,F321>:For 2nd spindle
RO0C-RO15C<F326,F327>:For 3rd spindle
RO0D-RO15D<F332,F333>:For 4th spindle
[Classification] Output signal
[Function] Posts a specified spindle speed. When constant surface speed control is
being performed, the spindle speed resulting from constant surface
speed control is posted. This signal consists of 16 binary code output
signals. The spindle speed and signal are related as follows:

Where, N is the value set in parameter No. 5612.
[Output condition] This signal is always output. Unless constant surface speed control is
being applied, the signal value changes only when Sxxxx is specified
by a program.
Maximum spindle speed signal MR0A-MR15A<F014,F015>:For 1st spindle
MR0B-MR15B<F324,F325>:For 2nd spindle
MR0C-MR15C<F330,F331>:For 3rd spindle
MR0D-MR15D<F336,F337>:For 4th spindle
[Classification] Output signal
[Function] Posts the maximum spindle speed specified by G92 Sxxxx. Whether
the spindle speed is clamped to this value only during constant surface
speed control or whether it is always clamped depends on the PMC
specifications. This signal consists of 16 binary code output signals.
The maximum spindle speed and signal are related as follows:

Where, N is the value set in parameter No. 5612.
[Output condition] This signal is always output. The signal value changes only when G92
Sxxxx is specified by a program.
Constant surface speed signal CSS<F001#7> :Logical AND of the values for all spindles
CSSA<F341#1> :for first spindle
CSSB<F342#1> :for second spindle
CSSC<F343#1> :for third spindle
CSSD<F344#1> :for fourth spindle
[Classification] Output signal
[Function] This signal indicates that constant surface speed control is in progress.
[Operation] "1" indicates that constant surface speed control mode (G96) is in
progress, while "0" indicates it is not.
[Remarks] Constant surface speed control can be exercised for one spindle at a
time. CSSA to CSSD are output for each spindle.
CSS is set to "1" when at least one spindle is in constant surface speed
control mode.
