PLC axis
If a container axis whose axis container has been enabled for rotation becomes a PLC axis,
the status change occurs only after completion of the axis container rotation.
Command axis
If a container axis whose axis container has been enabled for rotation traverses as a command
axis, the traversing movement is performed only after completion of the axis container rotation.
Oscillating axis
If a container axis whose axis container has been enabled for rotation becomes an oscillation
axis, the status change occurs only after completion of the axis container rotation.
External work offset
The "external work offset" is based on the machine coordinate system (MCS). Therefore, for
an active "external work offset", one of the container axes rejects the axis container rotation
with alarm 4022.
Axial frames
The axial frame of a channel axis, which is also a container axis, is no longer valid after an
axis container rotation. Since the axis container rotation assigns a new machine axis to the
channel axis, but the axial frame is referred to a machine axis, the rotation also changes the
axial frame. If the two frames do not coincide, a synchronization process (internal REORG) is
performed.
Note
The assignment between a channel axis and a machine axis is altered by the axis container
rotation. The current frames remain unchanged after a rotation. The user is responsible for
ensuring that the correct frames are selected after a rotation by programming basic frame
masks, for example.
Transformation
If a container axis is involved as a spindle in a transformation, the transformation must be
deselected before the enable of the axis container rotation.
Axis couplings
If an axis coupling is active for a container axis, the coupling with COUPOF must be deselected
before the enable of the axis container rotation. After completion of the rotation, the coupling
can be immediately selected again with COUPON. A new define of the coupling is not required.
