8.4 General Technical Data
Protection and features
•
Electronic motor thermal protection against overload.
•
Temperature monitoring of the heat sink ensures that the frequency converter trips if there is overtemperature.
•
The frequency converter is protected against short circuits between motor terminals U, V, W.
•
When a motor phase is missing, the frequency converter trips and issues an alarm.
•
When a mains phase is missing, the frequency converter trips or issues a warning (depending on the load).
•
Monitoring of the DC-link voltage ensures that the frequency converter trips when the DC-link voltage is too low
or too high.
•
The frequency converter is protected against ground faults on motor terminals U, V, W.
