Specifying Position Data Addresses (A0000 to A1999)
It is possible to use the contents of a position data address for position data or
an M code by specifying that address in an operand in an axis movement
command or M code. For example, when the following program is executed,
the contents of A1000 (123.45) will be used for the X-axis data and the con-
tents of A1001 (50) will be used for the M code.
Specifying Registers (E00) to (E31)
Position data can be specified indirectly by specifying a register (E00) to (E31)
in an axis movement command or M code. The relationship between the reg-
ister and position data contents is shown below.
Registers and position data are not assigned together to each task; they can
be used independently for different tasks.
The contents of registers are all cleared to zero only when power is turned ON
or when a restart is executed. Initialize register contents at the beginning of
the program by executing an command such as the SUBSTITUTION com-
mand (G63). Registers can contain values from 0 through 1999. An error will
occur if a value greater than 1999 is input in a register. The possible range of
values for position data is –39,999,999 through 39,999,999.
R Circle radius
S Specifies no error when there is no G31 interrupt input.
U (See
note.) U-axis
X X-axis
Y Y-axis
