B-64120EN/01 4.DESCRIPTION OF PARAMETERS
- 193 -
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.

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 through second spindles are used.
In this case, information about a spindle selected by the spindle
selection signal (SWS1-SWS2<G027#0-#1>) is output.
1: Information about each of the first through third spindles is
output on individual signals.
