3.6.3 4-3* Motor Feedback Monitoring
The parameter group includes monitoring and handling of motor feedback devices as encoders, resolvers etc.
4-30 Motor Feedback Loss Function
Option:
[0] Disabled
Function:
Select an analog input for scaling the settings in par. 4-16

sponding to 0% and 100% are defined in the analog input scaling, e.g. par. group 6-1*. This pa-
rameter is only active when par. 1-00
Loop .
Function:
Select an analog input for scaling the settings in par. 4-19 from 0% to 100% (or vice versa). The
signal levels corresponding to 0% and 100% are defined in the analog input scaling, e.g. par. group
6-1*. This parameter is only active when par. 1-00
Function:
Select which reaction the frequency converter should take if a feedback fault is detected Closed
Loop. The feedback fault is measured between the feedback (unfiltered) and the frequency that is
sent to the motor (16-13) - compensated for slip. The reaction will be activated if the measured
difference is more than specified in par. 4-31
Motor Feedback Loss Timeout
