if control is via the terminals). Configuring an alarm for this detected fault is recommended (assigned to a logic output, for
example) in order to indicate the cause of the stop.
[fallback spd]
(LFF): Change to fallback speed, maintained as long as the detected fault persists and the run command has
not been removed (1)
[Spd m aint.]
(rLS):
The drive maintains the speed being applied w hen the detected fault occurred, as long as the detected
fault is present and the run command has not been removed (1)
[Ram p s top]
(rMP): Stop on ramp
[Fast s top]
(FSt): Fast stop
[DC injection]
(dCI):

The event is triggered by comparison w ith the output frequency and the speed feedback according to the related parameters
configuration
FAnF, LAnF, dANF
and
tAnF.
The event is also triggered as soon as a RUN order is received, if the sign of the output frequency and the speed feedback are
in opposite w ay during
tAnF.
In case of a detected fault, the drive sw itch to a freewheel stop, and if the brake logic control function has been configured, the
brake command w ill be set to 0.
