Synchronization with axis position
If the new container axis assigned to the channel after a container rotation does not have the
same absolute machine position as the previous axis, then the container is synchronized
with the new position (internal REORG).
Note
SD41700 $SN_AXCT
_SWWIDTH[<axis container>] is only upd
ated for
a new configuration. If, after incremental rotation of the RTM/MS, the position of a circuit before the initial position
is reached, the container can be rotated normally in the forward direction to reach the initial
position of the container again. The drum or rotary table must however be turned back to the
original position, so that measuring and supply cables are not twisted.
