Axis container behavior after Power ON

The container always assumes the state defined in the machine data on Power On,
irrespective of its status when the power supply was switched off, i.e. the user must
distinguish between the actual status of the machine and the default setting and compensate
accordingly by specifying appropriate axis container rotations. He can do this, for example,
by means of an ASUB containing AXCTSWED in one channel while the other channels are still
in the RESET state.
2.7.4

Axis container response to mode switchover

A container axis in an axis container which has been enabled for rotation cannot be
traversed in JOG mode. An axis container can only be rotated in JOG mode by means of an
ASUB.
2.7.5

Axis container behavior in relation to ASUBs

An enabling command for axis container rotation cannot be canceled, i.e. if an axis container
rotation has been enabled in an ASUB, the enabling command remains effective even when
the ASUB has ended.
2.7.6

Axis container response to RESET

A reset cancels the enabling command for axis container rotation. The reset channel is then
no longer involved in the axis container rotation. The enabling commands in the other active
channels can effect a rotation. If all channels except one have been reset, the one remaining
active channel can set the rotary position directly with AXCTSWED.
2.7.7

Axis container response to block searches

An axis container rotation (AXCTSWE) cannot be enabled and activated in one block, but the
enabling and activation commands must be programmed in separate action blocks. In other
words, the axis container status changes in response to each separate rotation command as
a function of the status of other channels.
2.7.8

Supplementary conditions for axis container rotations

Note
The user must ensure by means of programming that
• the correct zero offsets are active after a container switch
• and that no transformations are active during the container switch.
