8.1 Axis Setting Commands
This section describes the axis setting commands.
8.1.1 Absolute Mode (ABS)
(1) Overview
The Absolute Mode (ABS) command causes the coordinate words that control axis movement to be treated as a
target position.
Once ABS mode has been executed, it remains in effect until Incremental Mode (INC) is next executed. ABS
mode is the default mode when the program operation is started.
Fig. 8.1 Movement Mode: Absolute Mode (ABS)
In this manual, the coordinate word that follows the logical axis name for the axis move command is expressed as
“reference position” or “position reference value.”
Program Current Position
The position on the work coordinate system when an axis is started moving by execution of an axis move command. And,
the work coordinate system is the coordinate system used in motion programs.
For information on the work coordinate system, refer to 8.3.1 Current Position Set (POS).

• The movement of a coordinate word designated in ABS mode is entirely different from that of the same coor-
dinate word designated in INC mode. Before starting operations, be sure to check that the ABS or INC com-
mand is specified correctly.
Failure to carry out this check may result in damage to equipment, serious personal injury, or even death.
