[Data type] Bit
SAR The spindle speed arrival signal is:
0 : Not checked
1 : Checked
SAT Check of the spindle speed arrival signal at the start of executing the
thread cutting block
0 : The signal is checked only when SAR, #0 of parameter 3708, is set.
1 : The signal is always checked irrespective of whether SAR is set.
NOTE
When thread cutting blocks are consecutive, the spindle
speed arrival signal is not checked for the second and
subsequent thread cutting blocks.
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.
