Motion Control Axis Behavior Model

The Motion Control Axis Behavior Model is based on elements of the S88 and Pack/ML standard state models. The CIP Axis State attribute indicates the current state of the Motion Control Axis. State transitions can be initiated either directly using the Axis Control request mechanism or by conditions that occur in either the controller or the motion device during operation.
Review the diagram for the behavior model to see how the axis state maps to identity object states.
Fault Reset State Transition Precedence
When an axis is in the Major Faulted state, the axis may transition to one of several different states in response to a Fault Reset event. Which state the axis transitions to is dependent upon other state/status conditions of the axis.
It is possible for more than one state condition to be present at the same time, for example. Shutdown, Start Inhibited, and so forth. Since the axis state model can only represent one state at any given time, the state of the axis is determined according to the following precedence:
  1. Major Faulted
  2. Shutdown
  3. Pre-Charge
  4. Start Inhibited
  5. Stopped
