6.4 General Technical Data

6.4.1 Protection and Features

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