2.7 Axis container
This call may only be used if the other channels, which have axes in the container are in the
RESET state.
Note
The axis container names allotted through the following machine data can be used for the
AXCTSWE and AXCTSWED commands:
MD12750 $MN_AXCT_NAME_TAB
Implicit wait
There is an implicit wait for the completion of a requested axis container rotation if one of the
following events has occurred:
● Part program language commands which will cause a container axis assigned to this axis
● GET(channel axis name) on a corresponding container axis
● the next AXCTSWE(CTi) for this axis container
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 AXCT_SWWIDTH[Container No.] is updated only for new configurations.
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.
Home channel of an axis container axis
If more than one channel has access authorization ("reference") to the axis via the machine
data, write authorization can be passed to the axis (setpoint input):
MD20070 $MC_AXCONF_MACHAX_USED
This machine data below creates a standard assignment between an axis and a channel:
MD30550 $MA_AXCONF_ASSIGN_MASTER_CHAN

container in this channel to move
Note
Even an IC(0) will result in a wait including synchronization where necessary (block-by-
block change in addressing according to increment even though absolute dimension is
set globally).
