Signal
Signals common to analog and serial spindles
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:
here, N is the value set in parameter No. 5612.
[Output condition] This signal is always output. The signal value changes only when an
Sxxxx command is specified in a program, unless constant surface
speed control is applied.
Maximum spindle speed signals MR0A-MR15A<F014,F015>:For 1st spindle
MR0B to MR15B<F324,F325>:For 2nd spindle
MR0C to MR15C<F330,F331>:For 3rd spindle
MR0D to MR15D<F336,F337>:For 4th spindle
[Classification] Output signal
[Function] Posts a 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.
