4. DESCRIPTION OF PARAMETERS
199
SSP The spindle speed read window (No. 138) reads the speed of the spindle:
0 : Specified by the spindle feedback selection signal SLPCA or SLPCB
<G064 bit 2 or 3>.
1 : Of the path if the SPW signal <G195 bit 0> is set to 1.
This parameter is used, for instance, to read the speed of a specific spindle
by the window (No. 138), not depending on the actual control.
SVD When the SIND signal is on, the detection of spindle speed fluctuation is:
0 : Disabled
1 : Enabled
SOC During constant surface speed control (G96 mode), the speed clamp by
the maximum spindle speed clamp command (M series: G92 S_; T series:
G50 S_;) is carried out:
0 : Before spindle speed override.
1 : After spindle speed override.
If this parameter is set to 0, the spindle speed may exceed the maximum
spindle speed (numeric value following S in G92 S_; (M series) or G50
S_; (T series)).
If this parameter is set to 1, the spindle speed is limited to the maximum
spindle speed.
The spindle speed is limited to the upper limit of spindle speed specified
in parameter No. 3772, irrespective of the setting of this parameter.
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).
