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 temper-
ature 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, Unit 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 in order to
ensure the performance of the drive.
