Introduction to Programming

Chapter 10

10-18

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.

Your 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 (control assumes G00 X0;)

M;

program stop (control assumes M00)

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.

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 your system installer.

Many of the addresses 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 your system installer.

Important: The formats in this table indicate the maximum number of

digits left and the maximum number of digits right of the decimal point for

each word. In many cases, they are not valid together since the control

allows a maximum of 8 total digits. Refer to your system installer’s

manual for specific formats.
