5.4 MANUAL ABSOLUTE ON/OFF
General
When performing manual operation (such as jog feed and manual
handle feed), the user can choose whether to reflect a moved distance in
the absolute coordinate system.
- When manual absolute turns on
If manual intervention is performed during automatic operation, the
distance moved by manual intervention is reflected in the absolute
coordinate system. This means that no displacement occurs between
the absolute coordinate system and machine coordinate system before
and after manual intervention. The tool path after manual intervention
is determined by bit 3 (ABS) of parameter No. 2409, as shown below.
- When manual absolute turns off
In automatic operation, a distance moved is reflected in an absolute
position indication. If a reset is performed after manual operation, or if
operation is started in automatic operation mode, however, the absolute
position indication represents the position before manual intervention,
and the absolute coordinate system after manual intervention is shifted
from the machine coordinate system by the distance moved by manual
intervention. So, the tool path after manual intervention is as shown
below.
When an absolute command is specified, or when bit
3 (ABS) of parameter No. 2409 is set to 1 and an
incremental command is specified, the path returns to
the programmed path.

When bit 3 (ABS) of parameter No. 2409 is set to 0, and an incremental
command is specified, the shifted path is followed.
