The inhibit/un-inhibit operation will also stop all motion on all axes associated to
the same motion module including breaking all gearing relationships. This stop
operation follows that of the shutdown fault action; servo action is immediately
disabled as is the drives power structure. Unless some external form of braking
capability is applied the axis will generally coast to a stop.
Axis ID
Usage Access Data Type Default Min Max Semantics of Values
Required - All
Set/
GSV
DINT - - - ID
Unique number assigned to axis on creation by configuration software.
The Axis ID is used by the Absolute Position Recovery feature during a
configuration software download to determine if a given axis is a new axis or
pre-existing axis. If the axis existed prior to the download, the controller saves
critical absolute position data associated with the axis before continuing the
download. Using the Axis ID, the controller is able to match the saved absolute
position data with the pre-existing axis and recover absolute position. Using the
saved data, absolute position will be recomputed to account for any motion that
occurred while the download was in process or while power was off.

GSV
USINT - - - Enumeration:
0 = Base
1 = Alternate 1
2 = Alternate 2
3-255 = Reserved
Determines the update schedule for the associated axis instance.
The default schedule setting of Base results in the axis being updated with every
scan of Motion Task, or the Base Update Period of the Motion Group. Alternate
1 and Alternate 2 schedule selections result in the axis being updated at multiples
of the Base Update Period given by the Alternate 1 and Alternate 2 Update
Multiplier attribute values of the Motion Group, or Alternate 1 Update Period
and Alternate 2 Update Period, respectively.
