Protection and Features:
•
Electronic thermal motor protection against overload.
•
Temperature monitoring of the heatsink ensures that the adjustable frequency drive 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 adjustable frequency drive is protected against short-circuits on motor terminals U, V, W.
•
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 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 adjustable
frequency drive can adjust the switching frequency and/or change the switching pattern in order to ensure the
performance of the adjustable frequency drive.
