The following timing chart shows how the input and signals behave.
utomatic operation
starting signal (STL)
ctive offset change mode
signal (CHGAO)
ctive offset changing
signal (MCHAO)
The offset selected by the active offset
selection signal (AOFS1 or AOFS2) is
changed by manual feed.
command such as Txxxx, or G54
specifies what tool compensation number
or workpiece coordinate system is to be
made valid.
Manual feed
(handle/incremental/jog)
mode
Operation restarts
with the new offset.
Operation is put at pause
(stop) to change the offset.

APL Specifies whether to preset the relative position indicator automatically
when the manual feed-based active offset change mode is selected, as
follows:
0: Do not preset.
1: Preset.
This signal is used to restore the previous value of an offset when it has
been changed in the manual feed-based active offset change mode.
Making axis movement by manual feed in such a way that the relative
position indicator (counter) becomes 0 can restore the previous value of
the offset.
