If it is 1, the corresponding axis is detached.
2) The following parameter enables the control axis detach function to
the corresponding axis.

#6 #5 #4 #3 #2 #1 #0
RMVx 0 : Controlled axis is connected
1 : Controlled axis is detached
Actual spindle speed does not arrive at a speed specified in a program.
Confirm the signal state using the PMCs diagnostic function
(PMCDGN).

#3 #2 #1 #0
SAR : When this signal is 0, spindle speed does not arrive at the specified speed.
This function is valid when parameter No. 3708#0=1.
Normally manual feedrate override function is used for jog feed.
But when DRN (dry run) signal turns on during an auomatic operation,
override values set with these signals become valid to the following speed
set by a parameter.
