Protection and Features:

Electronic thermal overload motor protection against overload.

Temperature monitoring of the heatsink ensures that the drive trips if 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 may vary for different power sizes, enclosures etc.). The drive has an auto derating function to avoid
it's heatsink reaching 95

°C.

The drive is protected against short-circuits on motor terminals U, V, W.

If a mains phase is missing, the drive trips or issues a warning (depending on the load).

Monitoring of the intermediate circuit voltage ensures that the drive trips if the intermediate circuit voltage is too
low or too high.

The drive is protected against earth faults on motor terminals U, V, W.
