In order to do dual spindle rotation speed check, please realize following
method.

CNC displays the actual spindle motor speed data directory from sensor
on diagnosis No.718.
PMC reads this actual spindle motor speed data by using PMC window
function (Reading Diagnosis Data : function code 33).
PMC compares this data with the reference speed, which is registered in
PMC data area.
If the actual spindle motor speed exceeds the reference speed, PMC
executes some action (for examples, emergency stop, message display,
reduce spindle override, so on).
