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
SETAL(61001)
ENDIF

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
.
