Continuous-path mode
If continuous-path mode is active in the channel and an axis container rotation is performed,
a subsequent programming of a container axis interrupts the continuous-path mode. The
interruption also occurs even when the container axis not a path axis.
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The axial frame of a channel axis, which is also a container axis, is no longer valid after an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.
