TSO During a threading or tapping cycle, the spindle override is:
0 : Disabled (tied to 100%).
1 : Enabled.
NOTE
During rigid tapping, the override is tied to 100%,
irrespective of the setting of this parameter.

[Data type] Bit
SAM The sampling frequency to obtain the average spindle speed
0 : 4 (Normally, set to 0.)
1 : 1
RSC In the constant surface speed control mode, the surface speed of a rapid
traverse block is calculated:
0 : In accordance with the coordinates of the end point.
1 : In accordance with the current value, as in cutting feed.
MSI In multi–spindle control, the SIND signal is valid
0 : Only when the first spindle is valid (SIND signal for the 2nd, 3rd
spindle becomes ineffective)
1 : For each spindle irrespective of whether the spindle is selected (Each
spindle has its own SIND signal).
MRS When the S 12–bit code signals and actual spindle speed signals are
output in multi–spindle control:
0: Signals common to the first and second spindles are used. In this case,
information about a spindle selected by the spindle selection signal
(SWS1–SWS3<G027#0–#2>) and SWS4<G026#3>) is output.
1: Information about each of the first and second spindles is output on
individual signals.

NOTE
1 To use this parameter, the multi–spindle control option and
serial spindle option are required.
2 To use the actual spindle speed signals, the actual spindle
speed output option is required.
SMC The function to check a large S command is:
0 : Not used.
1 : Used.
