Value range
In the crosswise data [0,3]
comparison between NCK
and 611D of any axis, an
actual-value error has
been detected
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.
