Example
For two action blocks with end-of-motion criteria for three axes:
Program code Comment
N01 G01 POS[X]=20 POS[Y]=30
IPOENDA[X] ; Last programmed IPOENDA end-of-motion
criterion
N02 IPOBRKA(Y, 50) ; Second action block for the Y axis
IPOENDA
N03 POS[Z]=55 FINEA[Z] ; Second action block for the Z axis
FINEA
N04 $A_OUT[1]=1 ; First action block for output as
digital output
N05 POS[X]=100 ;
N06 IPOBRKA(X, 100) ; Second action block for the X axis
IPOBRKA container
... ; For all programmed end-of-motion
criteria
TARGET: ; Block search target
The first action block contains the digital output:
$A_OUT[1] = 1.
The second action block contains the settings for the end-of-motion criteria:
for the X axis IPOBRKA / $SA_IPOBRAKE_BLOCK_EXCHANGE[AX1]=100
for the Y axis IPOBRKA / $SA_IPOBRAKE_BLOCK_EXCHANGE[AX2]=50
for the Z axis FINEA. The motion end condition IPOENDA last programmed is also stored for
the X axis.
10.7 Control by the PLC
PLC axes
PLC axes are traversed from the PLC and can move asynchronously to all other axes. The
travel motions are executed separate from the path and synchronized actions.

Concurrent positioning axes
Using function block FC18, for SINUMERIK 840D sl concurrent positioning axes can be
started from the PLC.
