Functions Common to All the Control Modes
t0 – Line loss;
t1 – Line loss detection;
t2 – Undervoltage actuation (F021 without Ride-Through);
t3 – Line return;
t4 – Line return detection;
t5 – Undervoltage actuation (F021 with Ride-Through).
If the line voltage produces an U
may occur, the values of P0321, P0322 and P0323 must be readjusted.
Note!
When one of the functions, Ride-Through or Flying Start, is activated, the parameter P0357 (Line
Phase Loss Time) is ignored, regardless of the adjusted time.
Note!
Cautions with the application:
It is mandatory the use of a line reactor to limit the inrush current when the line returns;
Use oversized Ultra-Rapid fuses or normal fuses for the same reason.
Note!
The Ride-Through function activation occurs when the power supply voltage is lower than the value
(P0321/1.35).
