Actual position
$A_XFAULTSI
(from SW 6.4.15)
0: In the crosswise data
comparison between NCK
and 611D of any axis, an
actual-value error has
been detected
1: In the crosswise data
comparison between NCK
and 611D of any axis, an
error was detected and
the delay time until
STOP B is initiated in this
axis is running or has
already expired.
[0,3] INT x x
$VA_XFAULTSI[axis]
(from SW 6.4.15)
0: For a crosswise data
comparison of this axis
between NCK and 611D,
an actual value error has
been detected
1: In the crosswise data
comparison between NCK
and 611D of any axis, an
error was detected and
the delay time until
STOP B is initiated in this
axis is running or has
already expired.
