CiA402 supported drive states according to the following state machine

flowchart TD
    S([●]) --> NRSO[Not Ready to Switch On]
    NRSO -->|Auto| SOD[Switch On Disabled]
    SOD -->|Shutdown| RTSO[Ready to Switch On]
    RTSO -->|Switch On| SO[Switched On]

    RTSO -->|Disable Voltage| SOD
    QSA -->|Enable Operation| OE
    QSA -->|Disable Voltage| SOD
    FS([●]) -->|Fault| FRA[Fault Reaction Active]
    FRA -->|Auto| F[Fault]
    F -->|Fault Reset| SOD

Some of these transitions are activated automatically like the transition from NotReadyToSwitchOn to SwitchOnDisabled and some others are automatically transitioned differently by different drive manufacturers;

Fields

NotReadyToSwitchOn = 0
SwitchOnDisabled = 1
ReadyToSwitchOn = 2
SwitchedOn = 3
OperationEnabled = 4
