Torque Notch Filter Low Frequency Limit
Usage Access T Data
Type
Default Min Max Semantics of Values
Optional - C Set/SSV
REAL FD 20 2000 Filter Frequency Units
This value sets the lower limit on the Torque Notch Filter Frequency Estimate
value for the Adaptive Tuning function. The frequency of an identified natural
resonance must be higher than this limit to be applied to the Torque Notch Filter
Frequency Estimate.
Torque Notch Filter Tuning Threshold
Usage Access T Data
Type
Default Min Max Semantics of Values
Optional - C Set/SSV T REAL 5 0 100 % Motor Rated
To be identified as a resonance frequency by the Adaptive Tuning function, the
resonance magnitude must exceed the Torque Notch Filter Tuning Threshold.
The magnitude of an identified natural resonance frequency must be higher than
this threshold value to be applied to the Torque Notch Filter Frequency Estimate.
Torque Notch Filter Frequency Estimate
Usage Access T Data
Type
Default Min Max Semantics of Values
Optional - C Get/GSV T REAL - - - Filter Frequency Units
This value represents the resonance frequency with the highest magnitude above
the Torque Notch Filter Tuning Threshold and between the Torque Notch Filter
Low Frequency Limit and the Torque Notch Filter High Frequency Limit as
identified by the Adaptive Tuning function.
The Torque Notch Filter Frequency Estimate value is initialized to zero when the
drive is power cycled or reset.
Torque Notch Filter Magnitude Estimate
Usage Access T Data
Type
Default Min Max Semantics of Values
Optional - C Get/GSV T REAL - - - % Motor Rated
This value represents the maximum magnitude for resonant peaks found above the
Torque Notch Filter Tuning Threshold and between the Torque Notch Filter
Low Frequency Limit and the Torque Notch Filter High Frequency Limit as
identified by the Adaptive Tuning function.
