Specifications
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.
