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.
