Quick Guide
Protection and features
•
Electronic thermal motor protection motor protection against overload.
•
Temperature monitoring of the heatsink ensures that the adjustable frequency drive trips in case of overtem-
perature.
•
The adjustable frequency drive is protected against short-circuits between motor terminals U, V, W.
•
If a motor phase is missing, the adjustable frequency drive trips and issues an alarm.
•
If a line phase is missing, the adjustable frequency drive trips or issues a warning (depending on the load).
•
Monitoring of the intermediate circuit voltage ensures that the adjustable frequency drive trips if the intermediate
circuit voltage is too low or too high.
•
The adjustable frequency drive is protected against ground faults on motor terminals U, V, W.
