To allow a previously granted enable to be canceled, the enable for at least one of the
channels (NCU1 or NCU2) involved on the axis container must still be pending at the time of
the cancellation. This means the cancel must be made before time
④.
Withdrawal is no longer possible as soon as all enable signals are available from all
channels of all NCUs (instant in time
④). In this case, the AXCTSWEC command has no effect.
No feedback is sent to the user.

2.2.4.8 Supplementary conditions
Axis mode
If a container axis in axis mode or as a positioning spindle (POSA, SPOSA) traverses, the
axis container rotates only after reaching the programmed end position.
Spindle
● A container axis active as a spindle continues to rotate during an axis container rotation.
● The control type of a spindle (speed / position control) refers to the associated machine
axis. The set control type "moves" with the machine axis when an axis container rotates.
● For commands that refer to the master spindle of the channel, a machine axis with the
corresponding spindle number must exist in the channel at the time of execution of the
command:
MD35000 $MA_SPIND_ASSIGN_TO_MACHAX[ <axis>] == number of the master spindle
Note
It is the sole responsibility of the user / machine manufacturer to ensure for spindles as
container axes that an appropriate machine axis must still exist in the channel after an
axis container rotation for the master spindle.
Work offsets
Note
It is the sole responsibility of the user / machine manufacturer to ensure that after an axis
container rotation the effective work offsets in the channel are adapted to the changed
machine axis assignments.
