5.6.15 cod 90 (ABS): Absolute address, cod 91 (INC): Incremental address
c
ABS
The address coordinates (x, y) used after the cod 90 instruction are regarded as absolute
values from the zero point (0, 0).
However, the coordinates of the arc center point (i, j), the radius (r), the travel by cod 71
(SINT) and cod 72 (DINT) are always regarded as incremental values. An address is
regarded as an absolute value when specification is omitted.
d
INC
The address coordinates (x, y) used after the
cod 91 instruction are regarded as incremen-
tal values from the present position.
Correction disabling function during incre-
mental drive
While special auxiliary relays M9163 (for the X
axis) and M9164 (for the Y axis) are ON, the
correction data set in cod73, cod74 and cod75
are ignored during incremental drive (performed
when cod91 is executed), and the machine
operates without correction.
