5.9 SEQUENCE NUMBER
At the start of a block in a program, an 8-digit sequence number can
be specified after address N. The sequence numbers of the program
being executed are displayed on the screen at all times. The sequence
number search function can be used to search for a sequence number
in a program.
5.10 ABSOLUTE PROGRAMMING / INCREMENTAL
PROGRAMMING
There are two ways to programming travels of the each axis; the
absolute programming, and the incremental programming. In the
absolute programming, coordinate value of the end position is
programmed. The incremental programming is used to program the
amount of each axis movement.
G90 and G91 are used to command absolute or incremental
programming, respectively.

G91 IP_ ; Incremental programming
T
When G code system A is used on the lathe system, an
absolute/incremental programming is not identified by a G90/G91
command but by an address word.
