•
The VLT AFD is protected against short-circuiting on motor terminals U, V, W.
•
The VLT AFD is protected against ground fault on motor terminals U, V, W.
•
Monitoring of the intermediate circuit voltage ensures that the VLT AFD cuts out if the intermediate circuit
voltage gets too high or too low.
•
If a motor phase is missing, the VLT AFD cuts out.
•
If there is a line fault, the VLT AFD is able to carry out a controlled deramping.
•
If a line phase is missing, the VLT AFD will cut out when a load is placed on the motor.
