When signal MDTHn is “1”, the axis detach function is in valid.
The control axis detach function becomes valid by the following
signal issued from the PMC or a CNC side parameter. Check as in the
following procedure :
1) The control axis detach signal (DTCHn) is input.

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

#7(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 PMC’s diagnostic function
(PMCDGN).

#4(SAR) : When this signal is 0, spindle speed does not arrive at the specified speed.
This function is valid when PARAM 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.
