Acceleration factor is set by the synchronized action:
WHEN TRUE DO ACC[X]=25 $R1 = $AA_ACC[X]
G4 F1
IF (RO <> $MA_ MAX_AX_ACCEL[X] * 0.25

end-of-motion criterion for single axes
Similar to the block change criterion for path interpolation (G601, G602 and G603) it is also
possible to program the movement end criterion for singleaxis interpolation in a part program
or in synchronized actions for main run axes: command/PLC axes.
Programmable criterion end-of-motion on reaching
FINEA[Axis]
"Exact stop fine"
COARSEA[Axis]
"Exact stop coarse"
IPOENDA[Axis]
"Interpolator stop" (IPO stop)
Axis: Channel axis name (X, Y ....), spindle (S1, ...)
The end-of-motion criterion set will affect how quickly or slowly part program blocks and
technology cycle blocks with singleaxis movements are completed.
The same applies for PLC positioning instructions via FC15/16/18.
The set end-of-motion criterion can be scanned with system variable $AA_MOTEND[Axis].
$AA_MOTEND[Axis] = 1 end-of-motion with "Exact stop fine"
$AA_MOTEND[Axis] = 2 end-of-motion with "Exact stop coarse"
$AA_MOTEND[Axis] = 3 end-of-motion with "IPO stop"
Note
Depending on whether $AA_MOTEND is programmed in a part program or a synchronized
action, the MOTEND value is output for the NC axes or the main-run axes.
The last programmed value is retained following a RESET.
