Option: Function:
This function is used to monitor
consistency in the feedback signal,
that is if the feedback signal is
available.
Select which action the frequency
converter should take if a feedback
fault is detected. The selected
action is to take place when the
feedback signal differs from the
output speed by the value set in
parameter 4-31 Motor Feedback
Speed Error for longer than the
value set in parameter 4-32 Motor
Feedback Loss Timeout.
