Tip:
* Specific Standby State after a Fault Reset is determined by applying the Fault
Reset State Transition Precedence Rules.
** When an axis is in the Stopped or Major Faulted states with Holding torque (as a
result of a Category 2 Stop), a Start Inhibit condition, Disable Request, or
Shutdown Request is used to execute the configured Stopping Action.
Valid transitions for the Axis State Model are defined in the following table:
