± MITn=1 shows interlock signal per axis and direction is input.
* For the T series, ± MITn is valid only for manual operation.
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.

1410 Dry run rate
The rate when the following override value is 100%.
g.CNC is waiting for
spindle speed arrival
signal to be input
h.Manual feedrate override
is 0% (dry run)
