Overcurrent
TeSys avatars with Overcurrent Alarm enabled signal an Overcurrent Alarm if the maximum phase current exceeds the Overcurrent Alarm Level in the motor Run state.
Avatars with Overcurrent Trip enabled signal an Overcurrent Trip if the maximum phase current exceeds the Overcurrent Trip Level in the motor Run state for a time longer than the Overcurrent Trip Delay.
