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
6 6
predefined level. An overload temperature cannot be reset until the temperature of the heatsink is below the
temperature limit. For details of these limits and level, refer to the VLT
frequency converter has an auto derating function to avoid its heatsink reaching 95 °C.
•
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 and
parameter setting).
•
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 is protected against earth faults on motor terminals U, V, W.
