HP? Hot and on Phire (fire)? If it gets to that point it's too late
Newer machines have load monitoring and you can program the machine with G-code to stop if the load is over the set limit.
If you don't have load monitoring it may be possible with more info from you but not by using the load meter because there is no current load reference variable in Fanuc macro.
More info means what is the condition where the drill would stop and return to the R level?
