Severity
The severity of an event determines the response of the inverter.
The events are logged in different places.
Severity "No response"
The event is completely ignored (does not affect the running process).
Severity "Warning"
The event does not severely affect the process and may be also ignored in consideration of safety aspects.
Severity "Fault"
The motor is brought to a standstill with the quick stop ramp.
–
The inverter will only be disabled after the quick stop is executed (motor at standstill) or after the time-out time set in 0x2826 has been elapsed. 
Timeout for error response
Timeout for error response –
Exception: In case of a serious fault, the inverter is disabled immediately. The motor has no torque (coasts). For details see the table "Event ID overview".
Severity "Trouble"
Just like "Fault", but the error state will be left automatically if the error condition is not active anymore.
–
Exception: In case of a severe trouble, the inverter is disabled immediately. The motor has no torque (coasts). For details see the table "Event ID overview".
–
The restart behaviour after trouble can be configured. Automatic restart after a fault
Automatic restart after a fault 
In the operating mode 0x6060 (P301.00) = "CiA: Velocity mode (vl) [2]", the behaviour in case of "Trouble" is just like in case of "Fault"!
