Feedback Only Axis Behavior Model

When the Motion Control Axis is not actively controlling axis motion (Control Mode = No Control), the state diagram reduces to the following for a Feedback Only axis or CIP Motion Encoder device type. Shaded regions show mapping of Axis States to corresponding Identity Object states. State transitions ending on shaded boxes can transition to any axis state within the box.
Motion control Axis Object State Model (Feedback Only)
TIP:
*Specific Standby state after a fault reset is determined by applying Fault Reset State Transition Precedence rules.
