FLr  [Catch on the fly] setting

Used to enable a smooth restart if the run command is maintained after the following events:
- Loss of line supply or simple power off
- Reset of current drive or automatic restart
- Freewheel stop
The speed given by the drive resumes from the estimated speed of the motor at the time of the restart, then
follows the ramp to the reference speed.
This function requires 2-wire control ( [2/3 wire control] (tCC) = [2 wire] (2C)) with [2 wire type] (tCt) = [Level]
(LEL) or [Fwd priority] (PFO).
v [No] (nO): Function inactive
v [Yes] (YES): Function active
When the function is operational, it activates at each run command, resulting in a slight delay
(1 second max.).
[Catch on the fly] (FLr) is forced to [No] (nO) if brake control [Brake assignment] (bLC) is assigned
