S12-bit code signals R01O to R12O<Fn036#0 to Fn037#3>,
R01O2 to R12O2<Fn200#0 to Fn201#3>,
R01O3 to R12O3<Fn204#0 to Fn205#3>,
R01O4 to R12O4<Fn270#0 to Fn271#3>,
[Classification] Output signal
[Function] If bit 3 (MRS) of parameter No. 3709 is 1, the spindle speed command
value calculated by the CNC is converted to a code signal from 0 to
4095, and the conversion result is output to a spindle. If MRS is set
to 0, the data of the currently selected spindle (when more than one
spindle is selected, the spindle with the smallest number) is output
only to R01O to R12O for the first spindle.
[Output condition] The relationship between the spindle speed command output value
(the value calculated by the CNC) and the value output to these
signals is plotted in the graph shown below. Note that for either a
serial or analog spindle, the output value on these signals is a value 0
to 4095 as a result of conversion from the spindle speed command
output value calculated by the spindle control function of the CNC;
the output value on these signals is not the actual output value.

Address P signals MSP00 to MSP15<Fn160#0 to Fn161#7>
[Classification] Output signal
[Function] The P value specified last by the S_P_; command is output.
When extended spindle names are used, the value in parameter No.
No.3781 corresponding to the spindle number of the spindle name
specified last is output.
[Output condition] When multi spindle control by using address P is enabled (bit 3 (MPP)
of parameter No. 3703 is 1), the P value specified in the S_P_;
command is output. When no S_P_; command has been specified
even once since power-up, the initial P value set in parameter No.
3775 is output.
When extended spindle names are used, the value in parameter No.
3781 corresponding to the spindle number of the spindle name
specified last is output. When no spindle name has been specified
even once, the value set in parameter No. 3775 is output.
