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, enclosures
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 in order to ensure the performance of the drive.
