SRV-63 series AC servo drives Detailed parameter description
-102-
Note:
When the set value of P1.19 is increasing, the sensitivity to the resonance is reducing.

This parameter is used to set the working mode of resonance detection and the resonance
frequency number presumed by self-adaptive notch filter as well as the action after presumption.
If the function is valid (1, 2, 3), the system will automatically collect data to conduct mechanical
resonance frequency analysis and the result is saved in P1.21 and P1.22. Users can set the
frequency of notch filter according to P1.21 and P1.22 to eliminate the mechanical resonance.
Note:
The setting value is invalid after gain adjustment.

This parameter is used to display the resonance frequency. When P1.20 is set to “1”, the system
will detect the frequency of the max. resonance point and display it by function codes.
Note:
1. Only when the speed reaches above 30r/min will the measuring value be correct.
