5-54 Pulse Filter Time Constant #29Range: Function:100ms*[5 -1000 ms]NOTICEThis parameter cannot be adjustedwhile the motor is running.Enter the pulse filter time constant. Thepulse filter dampens oscillations of thefeedback signal, which is an advantage ifthere is a lot of noise in the system. A hightime constant value results in betterdampening, but also increases the timedelay through the filter.5-55 Term. 33 Low FrequencyRange: Function:100 Hz* [0 - 110000Hz]Enter the low frequency correspondingto the low motor shaft speed (that islow reference value) inparameter 5-57 Term. 33 Low Ref./Feedb.Value.5-56 Term. 33 High FrequencyRange: Function:100 Hz* [0 - 110000Hz]Enter the high frequency correspondingto the high motor shaft speed (that ishigh reference value) inparameter 5-58 Term. 33 High Ref./Feedb.Value.5-57 Term. 33 Low Ref./Feedb. ValueRange: Function:0 ReferenceFeed-backUnit*[-999999.999 -999999.999ReferenceFeed-backUnit]Enter the low referencevalue [RPM] for the motorshaft speed. This is alsothe low feedback value,see alsoparameter 5-52 Term. 29Low Ref./Feedb. Value.5-58 Term. 33 High Ref./Feedb. ValueRange: Function:100 Reference-FeedbackUnit*[-999999.999 -999999.999ReferenceFeed-backUnit]Enter the high referencevalue [RPM] for the motorshaft speed.

Thelow-pass filter reduces the influence anddampens oscillations on the feedbacksignal from the control.This is an advantage if there is a lot ofnoise in the system.3.7.6 5-6* Pulse OutputsParameters for configuring the scaling and outputfunctions of pulse outputs. The pulse outputs aredesignated to terminal 27 or 29.
