NUMERIC Modals

This type of modal is referred to as modal type 1 in the postprocessor.  This type of modal is appropriate for most numeric input.  The general format of a NUMERIC modal code is:

NC CODE;M#1=TEXT

Since NUMERIC modals deal with numbers, the meaning of the number can effect the results of the NUMERIC modal.  A number can represent an incremental or absolute motion.  Most machine tools consider a motion of 0 in incremental mode to be a modal condition.  In incremental mode the value is only output when it is non-zero.  This type of value oriented modal will function differently in incremental mode.

The distinction between the two types of modals is important.  If the line "F#3.4;M#1=FEDRAT" is used in the $PP file, then feedrates of 0.0 will not be output in incremental mode!

Typical Example of Numeric Modal:
