Introduction to Programming
Chapter 10
10-19
Important: If backing up a table using a G10 program (such as the offset
tables or coordinate system tables), keep in mind the G10 program output
is generated in the current format of the control (LZS or TZS). If you
intend to transport this table to a different machine it must also be using the
same format.
Programming without Numeric Values
The system installer can also set an AMP parameter to generate an error or
use a value of zero for characters that are programmed without numeric
values. If this AMP feature is disabled, programming:
GX; rapid move to X zero
M; program stop
would result in the actions described in the comments following the blocks.
If the feature is enabled, the error “NUMERIC MISSING” would have
occurred upon execution of either of those blocks.
Word Descriptions and Ranges
Table 10.B shows, in alphabetical order, the addresses for words that are
recognized by the control, their typical formats, and their general
meanings. Since most of these formats are configured in AMP, refer to the
documentation prepared by the system installer.
Many of the addresses themselves can be altered in AMP. This table
assumes the most common names (such as X and Z for the main axes).
Alterable addresses are indicated by the note “AMP assigned”.
Later sections discuss these words in more detail, including variations in
their meanings when they are associated with certain G--codes. All words
discussed in this manual assume that the format and addresses in the
following table have not been changed by the system installer.
