270 Motion Object Attributes
Axis Configuration State
The Axis Configuration State attribute is used for debugging purposes to
indicate where in the axis configuration state-machine this axis presently is.
Even consumed and virtual axes utilize this attribute.
Axis State
The Axis State attribute indicates the operating state of the axis. Possible states
are axis-ready, direct drive control, servo control, axis faulted and axis
shutdown.
Output Cam Execution Targets
The Output Cam Execution Targets attribute is used to specify the number of
Output Cam nodes attached to the axis. This attribute can only be set as part
of an axis create service and dictates how many Output Cam Nodes are
created and associated to that axis. Each Output Cam Execution Target
requires approximately 5.4k bytes of data table memory to store persistent
data. With four Output Cam Execution Targets per axis, an additional 21.6k
bytes of memory is required for each axis.
The ability to configure the number of Output Cam Execution Targets for a
specific axis reduces the memory required per axis for users who do not need
Output Cam functionality, or only need 1 or 2 Output Cam Execution Targets
for a specific axis. Each axis can be configured differently.
Motion Object Status
Attributes
The Motion Status Attributes are comprised of all Motion Axis Object
variables that are “read-only”, i.e. attributes that you can get from the axis
object, but not set. This general category does not include attributes specific to
the software interface, which are covered in the section under Software
Interface Attributes.
