General Technical Data

Protection and Features

4.2.1
Electronic motor thermal protection against overload.
l
Temperature monitoring of the heat sink ensures that the drive trips if there is overtemperature.
l
The drive is protected against short circuits between motor terminals U, V, W.
l
When a motor phase is missing, the drive trips and issues a fault.
l
When a mains phase is missing, the drive trips or issues a warning (depending on the load).
l
Monitoring of the DC-link voltage ensures that the drive trips when the DC-link voltage is too low or too high.
l
The drive is protected against ground faults on motor terminals U, V, W.
