Protection and Features
•
Electronic thermal motor protection against overload.
•
Temperature monitoring of the heatsink ensures that the frequency converter trips when the temperature reaches
95 °C ± 5 °C. An overload temperature cannot be reset until the temperature of the heatsink is below 70 °C ± 5 °C
(Guideline - these temperatures vary for different power sizes and enclosures). The frequency converter has an
auto derating function to prevent 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).
•
Monitoring of the intermediate circuit voltage ensures that the frequency converter trips if the intermediate circuit
voltage is too low or high.
•
The frequency converter is protected against ground faults on motor terminals U, V, W.

Mains voltage low/mains drop-out:
During low mains voltage or a mains drop-out, the frequency converter continues until the intermediate circuit voltage drops
below the minimum stop level, which corresponds typically to 15% below the lowest rated supply voltage. Power-up and full
torque cannot be expected at mains voltage lower than 10% below the lowest rated supply voltage.
Supply frequency
The frequency converter power supply is tested in accordance with IEC61000-4-28, 50 Hz +4/-6%.
