Declaring Program Numbers and Axes

If the register name is in parentheses, i.e. (E00), the content of register will be

treated as a position data address.

For example, when the following program is executed, the contents of A1000

(123.45) will be used for the X-axis data and the contents of A1001 (50) will

be used for the M code.

If the register name is not in parentheses, i.e. E00, the command will operate

directly on the content that register. In the following example, the content of

E00 and E01 are added and the result is placed in E02.

Program block

The program number and axes being used must be declared at the beginning

of the program.

The following table shows the program numbers and axes that can be

declared for main programs and subroutines.

Main programs

P000 through P499

P500 through P999

There are two kinds of MC Unit programs, main programs and subroutines.

Main programs are assigned program numbers P000 through P499 and sub-

routines are assigned program numbers P500 through P999.

Every program must begin with a declaration of the program number and the

axes being used. Main programs end with a PROGRAM END command

(G79) and subroutines end with a SUBROUTINE END command (G73). This

declaration is made at the beginning of the program (block number N000); an

error (determined by CX-Motion) will occur if the declaration is made in a later

The MC Unit can contain up to 100 programs.
