MANUAL ABSOLUTE
[Function]
This signal selects whether to update the program coordinate system the amount moved with
manual operation (jog, handle, etc.).
[Operation]
(1) When "Manual absolute (ABS)" signal is OFF:
The amount moved with manual operation is not added to the absolute position register in the
controller. Thus, if manual is used during automatic operation, the axis will move in parallel the
amount moved manually at the end point of the block and the end point of the following blocks.
(The axis will move in parallel regardless of the absolute value/incremental value command in
the machining program.)
Z axis
(2) When "Manual absolute (ABS)" signal is ON:
The amount moved by manual operation is added to the absolute position register in the
controller, and the coordinate system is not changed. Thus, if manual operation is used during
automatic operation by absolute value command, the axis will return to the position commanded
at the end of the inserted block and following blocks. However, if the manual interrupt is an
incremental value command, the axis will move in parallel the amount moved manually. (The
axis will move in parallel regardless of the absolute value/incremental value command at the
end of the inserted block.)
