a) with the line returning before the time adjusted in P0332
The actuation of the Ride-Through function can be visualized at the outputs DO1/RL1, DO2/RL2, DO3/RL3,
DO4 and/or DO5 (P0275 to P0279), provided that they have been programmed in "24=Ride-Through".

Description:
This parameter sets the necessary time for the output voltage to reach the rated voltage value.
It is used by the Flying Start function as well as by the Ride-Through function (both in V/f mode), together with the
parameter P0332.
