2.3 System variables for synchronized actions
Reset behavior
With static synchronized actions (
position offset effective in $AA_OFF results in an immediate new overlaid movement. The
reset behavior with regard to $AA_OFF can therefore be set via the following machine data:
MD36750 $MA_AA_OFF_MODE, bit 1 = <value>
<value>
0
1
JOG mode
Execution of an overlaid movement because of $AA_OFF can also be enabled for JOG
mode:
MD36750 $MA_AA_OFF_MODE, bit 2 = <value>
<value>
0
1
A mode change to JOG mode is only possible when the current position offset has been
traversed. Otherwise the following alarm is displayed:
Alarm "16907 Action ... only possible in stop state"
Supplementary conditions
● Interrupt routines and ASUB

Meaning
The position offset in $AA_OFF is deselected with RESET
In the position offset in $AA_OFF is retained after RESET
Meaning
JOG mode: Overlaid movement because of $AA_OFF disabled
JOG mode: Overlaid movement because of $AA_OFF enabled
When an interrupt routine is activated, modal motion-synchronous actions are retained
and are also effective in the ASUB. If the subprogram return is not made with
modal synchronized actions changed in the asynchronous subprogram continue to be
effective in the main program.
REPOS
In the remainder of the block, the synchronized actions are treated in the same way as in
an interruption block. Modifications to modal synchronized actions in the ASUB are not
effective in the interrupted program. Polynomial coefficients programmed with
not affected by ASUB and
The polynomial coefficients from the calling program are active in the ASUB. The
