The maximum programmable value accepted by the control is 99,999,999.
The minimum is .000001 inch or .00001mm. The actual range of
programmable values depends on specifications determined by your
system installer.
By using AMP to establish the format of numeric values for words, your
system installer sets the “programming resolution” for axis motion, the
smallest programmable distance of axis motion.

Refer to your system installer’s documentation for the programming
resolutions and ranges in a specific system.
This section describes general features of the words used in programming.
Later chapters in this manual describe how to use these words in detail.
Axis words are made up of an axis name followed by the desired numeric
value for that word.
For axis names, the system installer chooses from:
A B C U V W X Y Z $X $Y $Z $B $C
These are assigned in AMP. This manual assumes primary axes one, two,
and three to be labeled X, Y, and Z respectively. Integrand words for these
axes are assumed by be I, J, and K respectively. Incremental or parallel
axis names for these axes are assumed to be U, V, W, respectively.
