Note
Increment
The increment of a axis container rotation is set via the setting data:
SD41700 $SN_AXCT_SWWIDTH
Further information
Diagnostics
The current status of a axis container can be read via the following system variables:
System variable
$AC_AXCTSWA[<name>]
$AN_AXCTSWA[<axis container>]
$AN_AXCTSWE[<axis container>]
$AN_AXCTAS[<axis container>]
Axis container rotation with implicit GET / GETD
The following machine data can be use to set that all container axes of the channel are
brought into the channel by means of an implicit
replacement is only possible again after the container rotation.
