Protection and Features
•
Electronic thermal motor protection against overload.
•
Temperature monitoring of the heatsink ensures that the frequency converter trips if the temperature reaches a
predefined level. An overload temperature cannot be reset until the temperature of the heatsink is below the
values stated in the tables on the following pages (Guideline - these temperatures may vary for different power
sizes, frame sizes, enclosure ratings etc.).
•
The frequency converter is protected against short-circuits on motor terminals U, V, W.
•
If a mains phase is missing, the frequency converter trips or issues a warning (depending on the load).
•
Monitoring of the intermediate circuit voltage ensures that the frequency converter trips if the intermediate circuit
voltage is too low or too high.
•
The frequency converter constantly checks for critical levels of internal temperature, load current, high voltage on
the intermediate circuit and low motor speeds. As a response to a critical level, the frequency converter can adjust
the switching frequency and/ or change the switching pattern to ensure the performance of the frequency
converter.
